Tsunami
Quantify the potential economic and insured loss impact of highly destructive, albeit rare, tsunami events.
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.
Spotlight
Recent Large Tsunami Events Were Key for Model Validation
RMS tested and validated the methodology used to model the entire tsunami life cycle against available ground-truth observation data for several recent historical events, starting with published earthquake slip distributions and comparing wave inundation observations and damage statistics.

RMS Japan Earthquake and Tsunami HD Model
The RMS® Japan Earthquake and Tsunami HD Model incorporates key research advances from the 2017 Japan Seismic Hazard Maps and lessons learned from the 2011 Great East Japan (Tōhoku) Earthquake Tsunami and 2016 Kumamoto Earthquake. Leveraging detailed damage statistics and claims data from recent events, the model assesses building performance due to ground shaking, tsunami inundation, fire following earthquake, liquefaction, and landslides. Together with interruption losses, it provides a comprehensive solution for managing and differentiating earthquake risk in Japan.

The core idea behind catastrophe modeling is that the architecture of risk quantification is the same whatever the peril.
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…
