A study reported in “The Oregonian” July 27, 2018 by Douglas Perry stating, “The big one is coming.”
The magnitude along the Cascadian Ridge of 700 miles will be between 8.7 and 9.2 Richter. It will a spawn a tsunami that will devastate the area. The article states the area is at least Portland northward to Seattle. That is a picture for major cities, currently there is seismic activity along the northern and southern boundary of the fault. Basically, prudent public policy has to extend along the entire fault.
A couple of things:
PNSN (Pacific Northwest Seismic Network) organized and managed by the University of Washington and the University of Oregon has significant graphs and information. This is not average public information, but, Americans can understand more than they are given credit. The university people have a long history recording the plate and seismic activity. Their website is pnsn.org.
The thing that has to be addressed is the need for better monitoring of seismic activity and tsunami.
In an article by Reuters written by Sharon Bernstein entitled “U.S. Pacific Northwest under prepared for tsunami, says expert”. Ms. Bernstein reports after the January 2018 Alaskan quake of 7.9 quake which caused tsunami alarms along west coast; large areas of the northwest USA is at risk without alarms. They need to be installed and the public educated as soon as possible.
There can be no excuses and no public authority should utter one word about cost. These are American lives. Experts in the region have already assessed the region and know where tsunamis can cause death and damage. Evacuation routes are absent in some places and there is building going on in areas where it should never occur.
In Hawai’i fissure eight is still very active and shows no signs of stopping with more than 700 homes lost.
