Dutchsinse: West Coast Earthquake Unrest

Dutchsinse

11/02/2015 — West Coast Earthquake Unrest — M4.2 strikes Arizona after M4.3 strikes California by Michael Janitch A noteworthy (and rather rare) M4.2 earthquake has struck Central Western Arizona. The West coast is showing signs of unrest -- within the past few hours we have seen TWO separate M4.0+ earthquakes strike along the Western edge of the North American Craton. The new flurry of West coast seismic unrest is obvious at this point. California was hit by a M4.3 earthquake just a few hour prior , and now Arizona has been hit by a similar M4.2 event -- happening over just a few hours time from one another. This activity along the West coast was forecast to occur in the Earthquake Forecast issued on October 31st - November 1 . We were expecting to see movement strike North California, and also in the Southwest United States - particularly along the edge of the craton.

This newest event measured 3.0 magnitude, and occurred near Needles, CA. This is certain proof that things are "on the move" along the West coast right now, have a plan and be prepared - just in case!
