Comprehensive View of Seismic Hazard for the United States

The RMS U.S. Earthquake Model is part of the RMS North America Earthquake Models suite which offer seamless seismic source coverage across the U.S., Canada and Mexico. For the RMS U.S. Earthquake Model, this allows users to assess seismic events outside the U.S. border that have the potential to cause losses to a U.S. portfolio. This provides a more complete view of events impacting exposure within the country along with efficient rollup of multi-national portfolios.

Latest View of Hazard

RMS U.S. earthquake modeling includes the latest data from the U.S. Geological Survey (USGS) 2014 National Seismic Hazard Mapping Project (NSHMP), including data from the third Uniform California Earthquake Rupture Forecast (UCERF3), the 2013 USGS Quaternary Fault and Fold Database for Alaska, and the latest source information for Hawaii.

Analysis of Liquefaction Risk

RMS invested significant resources to understand the major effects of liquefaction from the 2010-2011 Canterbury Earthquake Sequence in New Zealand. Using billions of dollars of claims data from these events in New Zealand, RMS has transferred its knowledge to develop a new probabilistic liquefaction model that covers all of North America, including the United States.

High-Resolution Amplification Model

High-resolution amplification model used in U.S. Earthquake modeling reflects the latest ground motion prediction equations, incorporating new science to better differentiate risk based on local site conditions as well as detailed basin amplification models of key areas.

U.S. Earthquake Model

Comprehensive, high-resolution U.S. earthquake modeling, incorporating the latest science.

Secondary Perils

Full picture of earthquake risk for the U.S. including tsunami, fire following earthquake, and earthquake sprinkler leakage.

Business Interruption

Damage functions calculated as a function of both direct facility damage and disruption to lifelines necessary for continued facility operations, such as water or electricity.

Building Characteristics

Advanced vulnerability modeling draws on claims analysis, analytical studies, expert site surveys, reports from historical earthquakes, and includes the latest research on the seismic performance of very tall buildings (those more than 40 stories).

Induced Seismicity

The U.S. Earthquake Model can include the effects of induced seismicity (or human activity, such as wastewater injection associated with fracking) on the frequency of modeled events.
