OPB’s What’s my Risk?

On the anniversary of the last Cascadia earthquake and tsunami 315 years ago, OPB has done an excellent series of stories called “Unprepared: Will We Be Ready for the Megaquake?”   As the articles points out, a large Cascadia earthquake and tsunami can occur anytime, and it reviews how prepared we are and compares it to the recent earthquake and tsunami in Japan.  They also have a nice little app called “What’s My Risk“.  You can put in your address to see where critical buildings are located nearby and what their risk of collapse are.   At the bottom of the page,  you can find out if  your local school has been retrofitted.   The information was available online, but the app shows it in an interactive and friendly way, making this information more transparent.  This is an exciting development.

Tsunami Mapping on the Oregon Coast

Posted on June 19th, by raskin in Blog. Comments Off on Tsunami Mapping on the Oregon Coast

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.  This latest generation tsunami inundation mapping started with the Cannon Beach map, shifted down to southern Oregon and is now completed for the coast and mouth of the Columbia River.   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.

The other set of maps in … Read More »
