An Integrated Engineering-Economic Vulnerability Assessment Tool to

Increase Tsunami Preparedness in Rural Coastal Counties

Yong Chen, Patrick Corcoran, Daniel Cox, and Bruce Weber

We are on the subduction zone and vulnerable to earthquake and tsunamis.

Well within the window of recurrence : 312 years since the last M9.

Probability: in the next 50 years, 10-14% chance of M9 and 37% chance of M8.
