NEWARK, Calif. - February 03, 2015 RMS, the world's leading catastrophe modeling firm, today announced that it has released its RMS® Global Tsunami Scenario Catalog. The catalog, which is the first of its kind in the industry, provides the most comprehensive global coverage of potential tsunami events on major subduction zones around the world. Insurers and reinsurers who write business along susceptible coastlines can use the Global Tsunami Scenario Catalog to assess their potential tsunami losses in regions of high exposure concentrations to support pricing, underwriting and capital allocation for their tsunami risk.

“The Global Tsunami Scenario Catalog helps companies to deepen their understanding of global tsunami-related inundation risk by highlighting where these extremely catastrophic events can occur and the multiple coastlines that could be impacted,” said Dr Renee Lee, tsunami expert and senior product manager at RMS. “Tsunami events have the potential to be highly catastrophic, and until recently, the industry has struggled to adequately assess this previously non-modeled and complex risk.”

The Global Tsunami Scenario Catalog includes close to 30 high-resolution tsunami inundation footprints generated from magnitude 8.9 to 9.6 mega-thrust earthquakes on subduction zone plate boundaries worldwide. The catalog includes potential tsunami scenarios that are not within the historical record, in addition to scenarios based on significant historical tsunami events. Each footprint provides the maximum inundation depth and extent for the impacted multi-country coastlines so that users can estimate the physical damage to local building stock.

“To minimize the losses and operational impacts caused by large tsunami events, underwriters and risk managers need the ability to understand the risk and then quantify the potential damage to individual locations,” said Lee. “The footprints provide the highest resolution available in combination with a numerically robust method of evaluating tsunami risk that exactly conserves the mass, momentum and energy of the tsunami to provide a more accurate prediction of the tsunami extent and inundation. ”

The RMS tsunami catalog was modeled taking into consideration the entire tsunami lifecycle, from initial wave generation, to deep ocean wave propagation and coastal inundation. The tsunami modeling approach was validated in both near-field and far-field experiments, using the tsunami water heights of five of the six largest magnitude earthquakes since 1900, including the 2011 Tohoku, Japan, 1964 Alaska, 1960 Valdivia, Chile, 2010 Maule, Chile and 2004 Indian Ocean events.

Coastal inundation was modeled on high-resolution integrated bathymetric-topographic digital elevation grids, taking into consideration variable land friction to accurately capture the extent and maximum inundation depth of water on land. “In the near-field, coastal deformation following a tsunamigenic event can significantly influence the inundation profile at the coastline,” said Lee. “This coastal deformation was captured within the model to account for post-event subsidence or upliftment.”
