Tsunami Inundation Database Portal

As part of a recently completed research project funded by the five US western states (California, Oregon, Washington, Alaska, and Hawaii) and coordinated by the Pacific Earthquake Engineering Research Center, a database of tsunami inundation was developed for the western States of the US.

NEW: Tsunami Design Guidelines for New Bridges have been released!

The PEER research project to develop bridge design guidelines for tsunami loads has recently concluded and released three reports summarizing the project methodology, investigations, and findings. The project was a multi-campus, multi-disciplinary research program that spanned five years, and it was funded through PEER by a Transportation Pooled-Fund that included Alaska, California, Hawaii, Oregon (lead state), Washington, and the Federal Highway Administration. The Cascadia subduction zone poses a direct threat for a major tsunami that could impact the coastlines of these of these five states. The purpose of the project was to develop the necessary probabilistic tsunami wave heights in coastal areas of the western states, followed by design guidelines for new bridges to withstand tsunami loads.

With a recent funding from the California Department of Transportation, NHR3 has developed this new web portal to access such the database, and illustrate the results. This portal can conveniently be used by researchers and practicing professional to access tsunami-inundation design values such as maximum wave height and flow velocity. With this Portal, users are able to extract tsunami properties from the simulation database based on user-specified location.

This effort has been commissioned by the Oregon Department of Transportation with additional funding of the other states through the Pacific Earthquake Engineering Research Center (PEER) and builds on previous work supported by the United States Geological Survey (USGS), PEER, the California Department of Transportation (Caltrans), the California Geological Survey (CGS) and American Society of Civil Engineering (ASCE).

This portal has been developed by Dr. Silvia Mazzoni at the UCLA Natural Hazard Risk and Resiliency Research Center (NHR3), in collaboration with Prof. Pat Lynett of USC and Tom Shantz of Caltrans.

 

The Natural Hazards Risk and Resiliency Research Center (NHR3) hosted a short workshop on the recently developed NHR3 Tsunami Inundation Portal on 27 July 2021. The objective of the workshop was to demonstrate features of the new portal and receive feedback. A recording of this workshop is shown below.
