Comprehensive Tsunami Modeling
RMS modeling follows the entire tsunami life cycle from ocean floor deformation and tsunami generation through wave propagation to coastal inundation.
The RMS numerical wave propagation and coastal inundation model provides a comprehensive hydrodynamic solution that captures the true character of tsunami events.
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.
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.
The extensive damage statistics from the 2011 Great East Japan (Tōhoku) Earthquake Tsunami inform the RMS modeling of building performance during tsunami.
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.
