Scary Quakes off N. California coast

23 03 2018

Strange Sounds M4.6 and M4.7 earthquakes hit near Eureka, California – Series of 24 tremors hit The Geysers, Ca

A magnitude 4.6 earthquake hit off the coast of Northern California Thursday morning at 9:24 a.m. about eight miles west of Humboldt Hill and roughly 11 miles away from Eureka. It was followed by a M4.7 earthquake Thursday evening at 8:09 p.m. about 29 miles southwest of Eureka. A tsunami was not expected as a result of the quakes. Meanwhile, a series of tremors is currently swarming The Geysers [next to San Andreas fault], again in California.” . . . (more + maps)

Earlier we posted a story showing why the Cascadia Subduction Zone is scary.

Another Big Quake Off Oregon’s FRAGILE Coast + Columbia Rumbles

9 08 2012

A 4.5 quake hit offshore from Eugene, Oregon right on that big plate.

At    44° 34.452,   129° 35.682

MAP of it.   It’s right next to an undersea volcano(!).

And yesterday The Watchers reported this:

New study shows Cascadia Subduction Zone earthquake risk to be much higher than previously thought

America’s Pacific Northwest has a 37% chance of being hit by a magnitude 8 or larger earthquake in the next 50 years, a new study shows. That’s more than double previous estimates of a 10-15% risk. Great Subduction Zone earthquakes are the largest earthquakes in the world, and can exceed magnitude 9.0. Earthquake size is proportional to fault area, and the Cascadia Subduction Zone is a very long sloping fault that stretches from mid-Vancouver Island to Northern California. . .  (more + graphics)

UH-OH. N.W. (US) Nuke Plants Sit on Much More Active Fault Than First Thought.

31 05 2011

Important new USGS report does not bode well for US nuke industry:

“. . . . A new paper by Sherrod and Richard Blakely accepted for publication May 2 highlights compelling new evidence that the Yakima Fold and Thrust belt may be much more seismically active than long thought. If true, these findings could reshape assumptions used in assessments of nuclear safety, just as regulators try to reassess the controversial energy source in the wake of the March 11 Tohoku earthquake in Japan.  . . . “
