Cascadia Superquake: Are Locals Ready For It? (Hint: No)
A recent story in the New Yorker, which draws from the latest geological science, says that within 50 years there's a good chance a massive earthquake and subsequent tsunami will destroy a sizable portion of the Pacific Northwest and potentially kill 13,000 people in the process.
And according to, "The Really Big One," the odds of this Cascadia quake within five decades are one in three for a large quake and one in ten for a more massive one.
So KPLU asked people on the streets of Seattle if they’re concerned about an earthquake and what, if anything, they’ve done to prepare for it. Click on the audio link (above) to hear their comments.
From Kathryn Schultz's July 20, 2015 New Yorker article which created the stir:
Under pressure from Juan de Fuca, the stuck edge of North America is bulging upward and compressing eastward, at the rate of, respectively, three to four millimetres and thirty to forty millimetres a year. It can do so for quite some time, because, as continent stuff goes, it is young, made of rock that is still relatively elastic. (Rocks, like us, get stiffer as they age.) But it cannot do so indefinitely. There is a backstop—the craton, that ancient unbudgeable mass at the center of the continent—and, sooner or later, North America will rebound like a spring. If, on that occasion, only the southern part of the Cascadia subduction zone gives way—your first two fingers, say—the magnitude of the resulting quake will be somewhere between 8.0 and 8.6. That’s the big one. If the entire zone gives way at once, an event that seismologists call a full-margin rupture, the magnitude will be somewhere between 8.7 and 9.2. That’s the very big one.
