The Cost of Shaking in Oklahoma: Earthquakes Caused by Wastewater Disposal

It was back in 2009 that the inhabitants of northern Oklahoma first noticed the vibrations. Initially only once or twice a year, but then every month, and even every week. It was disconcerting rather than damaging until November 2011, when a magnitude 5.6 earthquake broke beneath the city of Prague, Okla., causing widespread damage to chimneys and brick veneer walls, but fortunately no casualties.

The U.S. Geological Service had been tracking this extraordinary outburst of seismicity. Before 2008, across the central and eastern U.S., there were an average of 21 earthquakes of magnitude three or higher each year. Between 2009-2013 that annual average increased to 99 earthquakes in Oklahoma alone, rising to 659 in 2014 and more than 800 in 2015.

During the same period the oil industry in Oklahoma embarked on a dramatic expansion of fracking and conventional oil extraction. Both activities were generating a lot of waste water. The cheapest way of disposing the brine was to inject it deep down boreholes into the 500 million year old Arbuckle Sedimentary Formation. The volume being pumped there increased from 20 million barrels in 1997 to 400 million barrels in 2013. Today there are some 3,500 disposal wells in Oklahoma State, down which more than a million barrels of saline water is pumped every day.

It became clear that the chatter of Oklahoma earthquakes was linked with these injection wells. The way that raising deep fluid pressures can generate earthquakes has been well-understood for decades: the fluid ‘lubricates’ faults that are already poised to fail.

But induced seismicity is an issue for energy companies worldwide, not just in the South Central states of the U.S.. And it presents a challenge for insurers, as earthquakes don’t neatly label themselves ‘induced’ and ‘natural.’ So their losses will also be picked up by property insurers writing earthquake extensions to standard coverages, as well as potentially by the insurers covering the liabilities of the deep disposal operators.

Investigating the Risk

Working with Praedicat, which specializes in understanding liability risks, RMS set out to develop a solution by focusing first on Oklahoma, framing two important questions regarding the potential consequences for the operators of the deep disposal wells:

  • What is the annual risk cost of all the earthquakes with the potential to be induced by a specific injection well?
  • In the aftermath of a destructive earthquake how could the damage costs be allocated back to the nearby well operators most equitably?

In Oklahoma detailed records have been kept on all fluid injection activities: well locations, depths, rates of injection. There is also data on the timing and location of every earthquake in the state. By linking these two datasets the RMS team was able to explore what connects fluid disposal with seismicity. We found, for example, that both the depth of a well and the volume of fluid disposed increased the tendency to generate seismic activity.

Earthquakes in the central U.S. are not only shallow and/or human-induced. The notorious New Madrid, Mo. earthquakes of 1811-1812 demonstrated the enormous capacity for ‘natural’ seismicity in the central U.S., which can, albeit infrequently, cause earthquakes with magnitudes in excess of M7. However, there remains the question of the maximum magnitude of an induced earthquake in Oklahoma. Based on worldwide experience the upper limit is generally assumed to be magnitude M6 to 6.5.

Who Pays – and How Much?

From our studies of the induced seismicity in the region, RMS can now calculate the expected total economic loss from potential earthquakes using the RMS North America Earthquake Model. To do so we run a series of shocks, at quarter magnitude intervals, located at the site of each injection well. Having assessed the impact at a range of different locations, we’ve found dramatic differences in the risk costs for a disposal well in a rural area in contrast to a well near the principal cities of central Oklahoma. Reversing this procedure we have also identified a rational and equitable process which could help allocate the costs of a damaging earthquake back to all the nearby well operators. In this, distance will be a critical factor.

Modeling Advances for Manmade Earthquakes

For carriers writing US earthquake impacts for homeowners and businesses there is also a concern about the potential liabilities from this phenomenon. Hence, the updated RMS North America Earthquake Model, to be released in spring 2017, will now include a tool for calculating property risk from induced seismicity in affected states: not just Oklahoma but also Kansas, Ohio, Arkansas, Texas, Colorado, New Mexico, and Alabama. The scientific understanding of induced seismicity and its consequences are rapidly evolving, and RMS scientists are closely following these developments.

As for Oklahoma, the situation is becoming critical as the seismic activity shows no signs of stopping: a swarm of induced earthquakes has erupted beneath the largest U.S. inland oil storage depot at Cushing and in September 2016 there was a moment magnitude 5.8 earthquake located eight miles from the town of Pawnee – which caused serious damage to buildings. Were a magnitude 6+ earthquake to hit near Edmond (outside Oklahoma City) our modeling shows it could cause billions of dollars of damage.

The risk of seismicity triggered by the energy industry is a global challenge, with implications far beyond Oklahoma. For example Europe’s largest gas field, in the Netherlands, is currently the site of damaging seismicity. And in my next blog, I’ll be looking at the consequences.

Indonesia’s Protection Gap – How the Sumatra Earthquake Shows that Coverage Must Spread

On December 7, 2016, a shallow magnitude 6.5 earthquake struck northern Sumatra in Indonesia, severely damaging or destroying more than ten thousand homes and many businesses, as well as causing over a hundred deaths. The disaster struck a poorer area away from the major cities, where the standards of building design, construction methods, and material quality are not sufficient to withstand such an earthquake.

USGS Shake map for Mw 6.5 Earthquake

We have up-to-date research on local building design and construction practices in Indonesia, which we have incorporated into the latest version of the RMS® Indonesia Earthquake Model. This research was done last year when members of the RMS vulnerability team, including me, visited southeast Asia as part of the process to update the model. We held workshops with local earthquake engineering experts who practice there, and attended an earthquake engineering conference, as well as visiting commercial and industrial buildings, including those under construction, to see first-hand how they were designed and built.

International Conference – Jogja Earthquake in Reflection (May, 2016)

This on-the-ground research provided insights into Indonesia’s rules and practices around construction, seismic design, code enforcement, as well as information on the relative quantities of different types of buildings in the country. We discovered significant differences between mainstream construction and those buildings covered by earthquake insurance, namely:

  • Past earthquakes have demonstrated that single family dwellings and/or low rise buildings are the most vulnerable building types compared to those built for commercial and industrial use, because of a lack of engineering design, poor construction, and lower material quality.
  • Buildings outside of major cities are mostly low rises and they may not be designed for earthquake risk.
  • Major cities such as Jakarta, Bandung, and Surabaya enforce a strict structural design review process for the construction of mid- and high-rise buildings.
  • Insurance penetration rates are higher for commercial and industrial buildings in and near major cities, with much lower penetration for residential properties in rural areas.

It’s perhaps not surprising that if poorer communities have less insurance protection, that they also cannot afford to invest in the higher quality construction that is designed to better withstand earthquakes. This is one of the primary reasons for the ‘protection gap’. As these countries become more developed, there’s the potential for that gap to start closing. In fact, Indonesia is one of the fastest growing economies in southeast Asia, with the property insurance and (re)insurance market expanding rapidly.

But as the earthquake disaster demonstrated, there are still many poorer regions with low insurance penetration which are also prone to repeated natural disasters. Sadly, there is still a long way to go before people in those places benefit from the resilience in their built environment which other, richer parts of the world may take for granted.

Understanding Risk Accumulations in Taiwan’s Science Parks

“The 6.4 magnitude Tainan earthquake in February 2016 resulted in a sizeable insured loss from the high-tech industrial risks and reminded the insurance industry of the potential threat from the risk accumulated in science parks.” (A.M. Best Special Report, Sept 2016)

Reading the sentence above you might be forgiven for wondering why science parks would give insurers and reinsurers any particular cause for concern. But consider this statistic: although Taiwan’s three major science and industrial parks occupy only 0.1% of the island’s total land mass, they represent 16% of Taiwan’s overall manufacturing – they are hugely significant, both economically and with regards to the insured exposure in Taiwan.

For example, the Hsinchu Science Park (HSP), known for semiconductor production, employs more than 150,000 people and contributes over $32 billion in revenues – approximately 6% of national GDP. By one estimate HSP represents over $319 billion in total insured values. In addition, some of the latest high tech areas within HSP, such as advanced “clean rooms,” present additional challenges due to their vulnerability to ground shaking or power interruption. The importance of this risk was observed in February’s Tainan earthquake where some significant losses to high-tech industrial risks were caused by damage to the equipment and the related business interruption due to power outage.

Improving data quality for advanced and detailed modeling is an important way to manage these risks, concludes the A.M. Best report quoted above. This is so as to accurately assess the potential loss impact on insurers’ books. RMS has already been analysing earthquake risk in Taiwan for 12 years – long before this year’s Mw 6.4 event – and in that time our view of seismic risk in Taiwan has not changed, since our model benefits from spectral response-based hazard and damage functions, that even include local liquefaction and landslide susceptibilities.

The 1999 Chi-Chi Earthquake (known in Taiwan as the 921 Earthquake) was the key event in building the RMS® Taiwan Earthquake Model in terms of the quake’s seismicity, ground motion, soil secondary effects and building response. Since then there have been no significant events to justify a re-calibration of the components of the model. In fact, the damages observed in this year’s event were broadly in line with RMS’ expectations and validated the robustness of the current model.

But although A.M. Best views the Taiwan insurance industry as prudently managed with relatively high catastrophe management capability, there are still lessons to be learnt from the 2016 event, and RMS has solutions which offer additional insight into understanding the risk posed by these business parks in Taiwan.

Concentration of Exposure into Science Parks

The RMS® Asia Industrial Clusters Catalogs were released in 2014 to identify hotspots of exposure, and profile their risk. The locations and geographic extent of the science parks within Taiwan are detailed to help understand risk accumulations for industrial lines and develop more robust risk management strategies.

High Fragility of the Semiconductor Industry

For coding of Industrial Plants, the RMS® Industrial Facilities Model (IFM) captures the unique nature of different industrial risks, as a high percentage of property value is often associated with machinery and equipment (M&E) and stock. This advanced vulnerability model supports the earthquake model to define the damageability of a comprehensive set of industrial facilities more accurately, and calculate the financial risk to these specific types of facilities, including building, contents, and business interruption (BI) loss estimates. The IFM differentiates the risks for different types of business within the science parks, and highlights the higher fragility of semiconductor plants compared to other industrial units, as shown below.

taiwanblog2

Lessons Learnt?

The huge damage from the 1999 Chi Chi earthquake has not halted the rapid development of Taiwan’s science parks in this seismically active area – indeed the island’s third biggest science park has since been built there. But this year’s comparatively small Mw 6.4 event further highlighted the substantial exposures concentrated within this sector, reminding the industry of the potential for significant losses without sound accumulation management practices, informed by the best modeling insights.

Earthquake Hazard: What Has New Zealand’s Kaikoura Earthquake Taught Us So Far?

The northeastern end of the South Island is a tectonically complex region with the plate motion primarily accommodated through a series of crustal faults. On November 14, as the Kaikoura earthquake shaking began, multiple faults ruptured at the same time culminating in a Mw 7.8 event (as reported by GNS Science).

The last two weeks have been busy for earthquake modelers. The paradox of our trade is that while we exist to help avoid the damage this natural phenomenon causes, the only way we can fully understand this hazard is to see it in action so that we can refine our understanding and check that our science provides the best view of risk. Since November 14 we have been looking at what Kaikoura tells us about our latest, high-definition New Zealand Earthquake model, which was designed to handle such complex events.

Multiple-Segment Ruptures

With the Kaikoura earthquake’s epicenter at the southern end of the faults identified, the rupture process moved from south to north along this series of interlinked faults (see graphic below). Multi-fault rupture is not unique to this event as the same process occurred during the 2010 Mw 7.2 Darfield Earthquake. Such ruptures are important to consider in risk modeling as they produce events of larger magnitude, and therefore affect a larger area, than individual faults would on their own.

In keeping with the latest scientific thinking, the New Zealand Earthquake HD Model provides an expanded suite of events that represent complex ruptures along multiple faults. For now, these are included only for areas of high slip fault segments in regions with exposure concentrations, but their addition increases the robustness of the tail of the Exceedance Probability curve, meaning clients get a better view of the risk of the most damaging, but lower probability events.

Landsliding and Liquefaction

While most property damage has been caused directly by shaking, infrastructure has been heavily impacted by landsliding and, to a lesser extent, liquefaction. Landslides and slumps have occurred across the region, most notably over Highway 1, an arterial route. The infrastructure impacts of the Kaikoura earthquake are a likely dress rehearsal for the expected event on the Alpine Fault. This major fault runs 600 km along the western coast of the South Island and is expected to produce an Mw 8+ event with a probability of 30% in the next 50 years, according to GNS Science.

As many as 80 – 100,000 landslides have been reported in the upper South Island, with some creating temporary dams over rivers and in some cases temporary lakes (see below). These dams can fail catastrophically, sending a sudden increase of water flow down the river.

Liquefaction occurred in discrete areas across the region impacted by the Kaikoura earthquake. The Port of Wellington experienced both lateral and vertical deformation likely due to liquefaction processes in reclaimed land. There have been reports of liquefaction near the upper South Island towns (Blenheim, Seddon, Ward), but liquefaction will not be a driver of loss in the Kaikoura event to the extent it was in the Christchurch earthquake sequence.

RMS’ New Zealand Earthquake HD Model includes a new liquefaction component that was derived using the immense amount of new borehole data collected after the Canterbury Earthquake Sequence in 2010-2011. This new methodology considers additional parameters, such as depth to the groundwater table and soil-strength characteristics, that lead to better estimates of lateral and vertical displacement. The HD model is the first probabilistic model with a landslide susceptibility component for New Zealand.

Tsunami

The Kaikoura Earthquake generated tsunami waves that were observed in Kaikoura at 2.5m, Christchurch at 1m, and Wellington at 0.5m. The tsunami waves arrived in Kaikoura significantly earlier than in Christchurch and Wellington indicating that the tsunami was generated near Kaikoura. The waves were likely generated by offshore faulting, but also may be associated with submarine landsliding. Fortunately, the scale of the tsunami waves did not produce significant damage. RMS’ latest New Zealand Earthquake HD Model captures tsunami risk due to local ocean bottom deformation caused by fault rupture, and is the first model in the New Zealand market to do this, that is built from a fully hydrodynamic model.

Next Generation Earthquake Modeling at RMS

Thankfully the Kaikoura earthquake seems to have produced damage that is lower than we might have seen had it hit a more heavily populated area of New Zealand with greater exposures – for detail on damage please see my other blog on this event.

But what Kaikoura has told us is that our latest HD model offers an advanced view of risk. Released only in September 2016, it was designed to handle such a complex event as the Kaikoura earthquake, featuring multiple-segment ruptures, a new liquefaction model at very high resolution, and the first landslide susceptibility model for New Zealand.

New Zealand’s Kaikoura Earthquake: What Have We Learned So Far About Damage?

The Kaikoura Earthquake of November 14 occurred in a relatively low population region of New Zealand, situated between Christchurch and Wellington. The largest town close to the epicentral region is Blenheim, with a population near 30,000.

Early damage reports indicate there has been structural damage in the northern part of the South Island as well as to numerous buildings in Wellington. While most of this has been caused directly by shaking, infrastructure and ports across the affected region have been heavily impacted by landsliding and, to a lesser extent, liquefaction. Landslides and slumps have occurred across the northeastern area of the South Island, most notably over Highway 1, severing land routes to Kaikoura – a popular tourist destination.

The picture of damage is still unfolding as access to badly affected areas improves. At RMS we have been comparing what we have learned from this earthquake to the view of risk provided by our new, high-definition New Zealand Earthquake model, which is designed to improve damage assessment and loss quantification at location-level resolution.

No Damage to Full Damage

The earthquake shook a relatively low population area of the South Island and, while it was felt keenly in Christchurch, there have been no reports of significant damage in the city. The earthquake ruptured approximately 150 km along the coast, propagating north towards Wellington. The capital experienced ground shaking intensities at the threshold for damage, producing façade and internal, non-structural damage in the central business district. Although the shaking intensities were close to those experienced during the Cook Strait sequence in 2013, which mostly affected short and mid-rise structures, the longer duration and frequency content of the larger magnitude Kaikoura event has caused more damage to taller structures which have longer natural periods.

From: Wellington City Council

Within Wellington, cordons are currently in place around a few buildings in the CBD (see above) as engineers carry out more detailed inspections. Some are being demolished or are set to be, including a nine-story structure on Molesworth Street and three city council buildings. It should be noted that most of the damage has been to buildings on reclaimed land close to the harbor where ground motions were likely amplified by the underlying sediments.

Isolated incidences of total damage in an area of otherwise minor damage demonstrate why RMS is moving to the new HD financial modeling framework. The RMS RiskLink approach applies a low mean damage ratio across the area, whereas RMS HD damage functions allow for zero or total loss – as well as a distribution in between which is sampled for each event for each location. The HD financial modeling framework is able to capture a more realistic pattern of gross losses.

Business Interruption

The Kaikoura Earthquake will produce business interruption losses from a variety of causes such as direct property or content damages, relocation costs, or loss of access to essential services (i.e. power and water utilities, information technology) that cripple operations in otherwise structurally sound buildings. How quickly businesses are able to recover depends on how quickly these utilities are restored. Extensive landslide damage to roads means access to Kaikoura itself will be restricted for months. The New Zealand government has announced financial assistance packages for small business to help them through the critical period immediately after the earthquake. Similar assistance was provided to businesses in Christchurch after the Canterbury Earthquake Sequence in 2010-2011.

That earthquake sequence and others around the world have provided valuable insights on business interruption, allowing our New Zealand Earthquake HD model to better capture these impacts. For example, during the Canterbury events, lifelines were found to be repaired much more quickly in urban areas than in rural areas, and areas susceptible to liquefaction were associated with longer down times due to greater damage to underground services. The new business interruption model provides a more accurate assessment of these risks by accounting for the influence of both property and contents damage as well as lifeline downtime.

It remains to be seen how significant any supply chain or contingent business interruption losses will be. Landslide damage to the main road and rail route from Christchurch to the inter-island ferry terminal at Picton has disrupted supply routes across the South Island. Alternative, longer routes with less capacity are available.

Next Generation Earthquake Modeling at RMS

RMS designed the update to its New Zealand Earthquake High Definition (HD) model, released in September 2016, to enhance location-level damage assessment and improve the gross loss quantification with a more realistic HD financial methodology. The model update was validated with billions of dollars of claims data from the 2010-11 Canterbury Earthquake Sequence.

Scientific and industry lessons learned following damaging earthquakes such as last month’s in Kaikoura and the earlier event in Christchurch increase the sophistication and realism of our understanding of earthquake risk, allowing communities and businesses to shift and adapt – so becoming more resilient to future catastrophic events.

Prudential Regulation Authority on the Challenges Facing Cyber Insurers

Most firms lack clear strategies and appetites for managing cyber risk, with a shortage of cyber domain knowledge noted as a key area of concern. So said the Prudential Regulation Authority, the arm of the Bank of England which oversees the insurance industry, in a letter to CEOs last week.

This letter followed a lengthy consultation with a range of stakeholders, including RMS, and identified several key areas where insurance firms could and should improve their cyber risk management practices. It focussed on the two distinct types of cyber risk: affirmative and silent.

Affirmative cover is explicit cyber coverage, either offered as a stand-alone policy or as an endorsement to more traditional lines of business. Silent risk is where cover is provided “inadvertently” through a policy that was typically never designed for it. But this isn’t the only source of silent risk: it can also leak into policies where existing exclusions are not completely exhaustive. A good example being policies with NMA 2914 applied, which excludes cyber losses except for cases where physical damage is caused in any cyber-attack (eg. by fire or explosion).

The proliferation of this silent risk across the market is highlighted as one of the key areas of concern by the PRA. It believes this risk is not only material, but it is likely to increase over time and has the potential to cause losses across a wide range of classes, a sentiment we at RMS would certainly echo.

The PRA intervention shines a welcome spotlight and adds to the growing pressure on firms to do more to improve their cyber risk management practices. These challenges facing the market have been an issue for some time, but the how do we help the industry address them?

The PRA suggests firms with cyber exposure should have a clearly defined strategy and risk appetite owned by the board and risk management practices that include quantitative and qualitative elements.

At RMS our cyber modeling has focussed on providing precisely this insight, helping many of the largest cyber writers to quantify both their silent and affirmative cyber risk, thus allowing them to focus on growing cyber premiums.

Shrugging Off a Hurricane: A Three Hundred Year Old Culture of Disaster Resilience

If a global prize was to be awarded to the city or country that achieves the peak of disaster resilience, Bermuda might be a fitting first winner.

This October’s Hurricane Nicole made direct landfall on the island. The eyewall tracked over Bermuda with maximum measured windspeeds close to 120 mph. Nonetheless there were there were no casualties. The damage tally was principally to fallen trees, roadway debris, some smashed boats and many downed utility poles. The airport opened in 24 hours, with the island’s ferries operating the following day.

Bermuda’s performance through Nicole was exemplary. What’s behind that?

Since its foundation in 1609 when 150 colonists and crew were shipwrecked on the island, Bermuda has got used to its situation at the heart of hurricane alley. Comprising 21 square miles of reef and lithified dunes, sitting out in the Atlantic 650 miles west of Cape Hatteras, a hurricane hits the island on average once every six or seven years. Mostly these are glancing blows, but once or twice a century Bermuda sustains direct hits at Category 3 or 4 intensity. Hurricane Fabian in 2003 was the worst of the recent storms, causing $300 million of damage (estimated to be worth $650 million, accounting for today’s higher prices and greater property exposure). The cost of the damage from Hurricane Gonzalo in 2014 was about half this amount.

How did Bermuda’s indigenous building style come to adopt such a high standard of wind resistance? It seems to go back to a run of four hurricanes at the beginning of the 18th Century. First, in September 1712 a hurricane persisted for eight hours destroying the majority of wooden buildings. Then twice in 1713 and again more strongly in 1715 the hurricane winds ruined the newly rebuilt churches. One hurricane can seem like an exception, four becomes a trend. In response, houses were constructed with walls of massive reef limestone blocks, covered by roofs tiled with thick slabs of coral stone: traditional house styles that have been sustained ever since.

The frequency of hurricanes has helped stress test the building stock, and ensure the traditional construction styles have been sustained. More recently there has been a robust and well-policed building code to ensure adequate wind resistance for all new construction on the island.

Yet resilience is more than strong buildings. It also requires hardened infrastructure, and that is where Bermuda has some room for improvement. Still dependent on overhead power lines, 90 percent of the island’s 27,000 houses lost power in Hurricane Nicole – although half of these had been reconnected by the following morning and the remainder through that day. Mobile phone and cable networks were also back in operation over a similar timescale. Experience of recent hurricanes has ensured an adequate stockpile of cable and poles.

Expert Eyes on the Island

It helps that there is an international reinsurance industry on the island, with many specialists in the science of hurricanes and the physics and engineering of building performance on hand to scrutinize the application of improved resilience. Almost every building is insured, giving underwriters oversight of building standards. Most importantly, the very functioning of global reinsurance depends on uninterrupted connection with the rest of the world, as well as ensuring that on-island staff are not distracted by having to attend to their family’s welfare.

Bermuda’s experience during Nicole would merit the platinum standard of resilience adopted by the best businesses: that all functions can be restored within 72 hours of a disaster. The Bermuda Business Development Agency and the Association of Bermuda Insurers and Reinsurers were fulsome in their praise for how the island had withstood the hurricane. The strong and widely-owned culture of preparedness, reflects the experience of recent storms like Gonzalo and Fabian.

Stephen Weinstein, general counsel at RenaissanceRe, commented “It’s remarkable that one day after a major hurricane strike, Bermuda is open for business, helping finance disaster risk worldwide, and poised to welcome back business visitors and vacationers alike.”

In early 2017, RMS will issue an update to Bermuda wind vulnerability in the version 17 software release as part of a broader update to the 33 islands and territories covered by the North Atlantic Hurricane Models. Updates to Bermuda vulnerability will consider past hurricane observations and the latest building code research.

Terrorism Insurance Under a Trump Presidency

It is likely that very few of the 60 million U.S. citizens who voted for Donald Trump would have done so because of his stance on terrorism insurance. Only because terrorism insurance is too arcane an issue to have come up in the presidential debates. However, many of the nation’s wavering voters may have been swayed by his pledge to make America safer from the scourge of terrorism. Under his presidency, border security will surely be tightened – even if no frontier wall is ever built and changes made to entry decisions for Syrian Muslim refugees into the United States.

Reauthorization of TRIA – Talks Start in 2018

On January 12, 2015, the Terrorism Risk Insurance Program Reauthorization Act of 2015 was signed into law by President Obama. This third extension of the original 2002 Terrorism Risk Insurance Act (TRIA) will sunset at the end of 2020, coinciding with the end of the first term of the Trump presidency. In the drafting of the 2015 reauthorization bill, detailed consideration was given by the House Financial Services Committee to alternative wordings that would have reduced the coverage provided by the U.S. government insurance backstop. One such alternative would have focused U.S. government involvement in the terrorism insurance market on covering terrorism losses from extreme attacks using weapons of mass destruction. When the future of terrorism risk insurance is raised once more on Capitol Hill in 2018, the Republican White House and Congress are likely to seek to further extend the private terrorism insurance market. Though I consider this to be contingent on President Trump keeping his pledge to keep America safe until then.

Balancing Civil Liberties in the Face of Reducing Terrorism Risk

In the democracies of the western alliance, the balance of keeping people safe from terrorism and preserving civil liberty is much debated issue. After the July 2005 London Transport bombings, the head of the British security service, MI5, warned that ‘there needs to be a debate on whether some erosion of civil liberties may be necessary to improve the chances of our citizens not being blown apart as they go about their daily lives’. On a national scale across America, a similar debate was prevalent during the 2016 U.S. presidential election. It may seem that in this instance, the champion of civil liberties, minority rights, and political correctness lost to the conservative advocate of oppressive counter-terrorism action and profiling of terrorist suspects.

Regardless of who occupies the White House, however, terrorist plots against the U.S. will persist and terrorists must be stopped before they move to their attack targets. Success in interdicting these plots depends crucially on intelligence gathered from electronic surveillance. It is well-documented that more intrusive surveillance can successfully increase the chances of lone wolf plots being stopped. And President-elect Trump has already affirmed his readiness to authorize more surveillance. He can claim a public mandate for this: for America to be great again, it has to be safe again – even from lone wolf terrorist plots. After the Orlando nightclub attack on June 12, 2016, perpetrated by the radicalized son of an Afghan immigrant, Donald Trump said that ‘we cannot afford to be politically correct anymore’. And in fighting global Islamist extremism vigorously, he may be able to count on President Putin’s support. While the two world leaders differ on geopolitics, their mutual respect as a President may be maintained through abrasive counter-terrorism action.

When Michael Chertoff was appointed Secretary of Homeland Security, President George W. Bush told him not to let 9/11 happen again – and he didn’t. President-elect Trump will expect a similarly impressive clean sheet. On a more personal level he also has a special interest in increased security against terrorist attacks. His own real estate empire includes some notable potential terrorist targets, including high-profile landmark buildings bearing his name. While the New York Stock Exchange has too tight security to be attacked, in contrast, the Trump Building on Wall Street has easy public access. There are numerous opportunities for terrorist target substitution.
