US: Fast walking could spare thousands from North West tsunami, study says

A new analysis published Monday shows more than 100,000 people are at risk from a tsunami on the US Northwest coast — but the outlook isn’t uniformly grim, reports the Seattle Times.

According to the article, in many communities, residents should be able to make it to high ground in time simply by walking at a brisk pace, when tsunami surges hit, as is expected in some parts of the coast within 15 to 30 minutes of an earthquake on the Cascadia Subduction Zone. The analysis takes the most comprehensive look yet at the threat along the 700-mile-long coast of Washington, Oregon and Northern California.
