2/23/2017 — Nightly Earthquake Update + Forecast — West Coast / Pacific Northwest M4.8 + M4.2 earthquakes

A new series of moderate sized earthquakes (near M5.0) have struck the Pacific Northwest United States and Vancouver BC Canada.

Washington State was struck by a M4.2 after months without any similar sized earthquake activity.  Just a short time later (less than a few hours) another M4.8 earthquake struck nearby at Vancouver Island British Columbia.

Areas within the Continental United States need to be alerted to the possibility of M4.0 range seismic activity to be returning to the midwest, and California.

This new round of upper M4.0 seismic activity will place pressure to the South by Southeast upon the interior edge of the North American Craton.  This new pressure may result in similar sized activity returning into Northern California, and a swarm topping out near M4.0 at the fracking operations in the midwestern plains (Oklahoma).

Certainly, keep watch over the next several (4-5) days for possible compensation movement in the areas to the East by Southeast from Vancouver / Washington State.   This includes areas such as Yellowstone (into Idaho), and Northern California into Southern California.

_______

The M4.2 in Washington State was preceded by a noteworthy  M3.4 earthquake which struck Southern California off the coast of Santa Barbara — directly next to an offshore oil drilling / pumping platform.

The nearest drilling platform is named “Platform Hondo”. 

The oil drilling / pumping platform is located approximately 2 miles East of the earthquake epicenter.

In case you are not aware, drilling operations (oil, gas, and geothermal) are vulnerable to incoming seismic pressure from other nearby regions.    The pumping operations begin showing movement in the days before larger movement strikes off the West coast.
