Tsunami inundation maps
DOGAMI has just released an amazing series of tsunami maps for the entire Oregon coast. They include the latest tsunami evacuation maps that show the inundation area of the largest tsunami generated from a distant event (in this case a tsunami generated by a subduction zone earthquake generated in Alaska), and a worst case Cascadia earthquake and tsunami.

These maps build on the previous generation maps and, by incorporating the best current science and modeling, can help prevent the significant loss of life such as experienced in Tohoku. The proviso is that Oregon and the coastal communities must maintain effective tsunami evacuation planning and education.
