While mega-tsunamis on the scale of Japan’s 2011 Tohoku disaster are rare, they can and will occur again. Rapid development of global coastlines necessitates understanding of this peril. - Dr. Renee Lee, tsunami expert and Senior Manager of Model Product Management |

Understanding Tsunami Risk: Assessing Local and Ocean-wide Impacts from Mega-Quakes
The 2004 Indian Ocean and 2011 Tohoku, Japan, tsunami events are among the most catastrophic events in recent history, causing widespread devastation and billions in losses.
The RMS Global Tsunami Scenario Catalog is the first global tsunami modeling solution available for this high-resolution peril, offering new insights into tsunami risk associated with magnitude 8.9 to 9.6 earthquakes.
Our scenarios include local and ocean-wide impacts to identify where mega-earthquakes have the potential to occur. Global coverage enables you to assess potential impacts from far-field events on local markets. Coastal inundations are modeled at high resolution using the latest available bathymetry and topography data sets appropriate for each region.
Robust Modeling Approach
Well-validated methodology, based on a full numerical model of the tsunami life cycle, takes into account local ground subsidence and variable land friction. The extent of each scenario helps you understand the correlations in your global exposures at risk.
Estimate Tsunami Impacts
Each footprint provides the maximum inundation depth and extent for impacted multi-country coastlines so you can more accurately estimate the potential physical damage to local building stock.
Historical and Potential M9 Scenarios
RMS scenarios are based on events generated on subduction zones that have produced tsunamis in the past or where large tsunamis could be generated, and comprises 29 scenarios identified for their potential to impact global coastlines.
