Quantifying Rare Events

Earthquakes generate tsunami waves typically through large-scale deformations of the ocean floor and can cause devastating impacts to coastal communities.

Mega-Thrust Events

Subduction zone earthquakes (M8.5+) can create devastating basin-wide tsunami events, which require a keen understanding of exposure accumulations and portfolio stress testing.

Locally High Hazard

RMS tsunami solutions focus on the exposures at highest risk to large mega-thrust events including the Pacific Northwest (U.S. and Canada) as well as coastlines in Japan and New Zealand.

Correlated Losses

RMS models have correlated event sets to consider the impacts of earthquakes and their resulting tsunami together on ground-up and gross losses.

Comprehensive Tsunami Modeling

RMS modeling follows the entire tsunami life cycle from ocean floor deformation and tsunami generation through wave propagation to coastal inundation.

Hydrodynamic Modeling

The RMS numerical wave propagation and coastal inundation model provides a comprehensive hydrodynamic solution that captures the true character of tsunami events.

Coastal Deformation

Tsunami life-cycle modeling captures the coastal elevation changes as large subduction zone earthquakes can raise or lower the coastline dramatically, affecting the impacts of tsunami waves.

High Resolution

Tsunami is a high-resolution peril as coastal inundations and losses are sensitive to small variations in tsunami-wave frequencies, ground elevation, and land use.

Building Performance

The extensive damage statistics from the 2011 Great East Japan (Tōhoku) Earthquake Tsunami inform the RMS modeling of building performance during tsunami.

The Storm Surge and the Tsunami

The core idea behind catastrophe modeling is that the architecture of risk quantification is the same whatever the peril. While a hurricane is not an earthquake, building a hurricane catastrophe model has elements in common with an earthquake catastrophe model. Stochastic event occurrence, the hazard footprint, the damage mechanism, clustering, post-event loss amplification are all shared concepts. While on the university campus, disciplines may retain their…

The Problem of Real and Unreal Tsunamis

Indonesia was beset by disasters in 2018, including two high casualty local tsunamis: in coastal western Sulawesi – impacting the city of Palu, on September 28, and around the Sunda Strait, between Java and Sumatra, on December 22. These events may have appeared unusual, but the great subduction zone tsunamis, like those in the Indian Ocean in 2004 and Japan in 2011, have reset our imagination. Before 2004, forty years had passed without any transoceanic…

How to Maintain Awareness of Tsunami Risk

Today is World Tsunami Awareness Day — designated by the United Nations General Assembly, and according to the United Nations Office for Disaster Risk Reduction (UNISDR), on average, tsunami events have a higher mortality rate than any other hazard. Over the past 20 years (1998-2017) tsunamis have claimed more than 250,000 lives and are also attributable for US$280 billion of the US$661 billion of total recorded economic losses for…
