Back-To-Back Earthquakes Shake California’s Volcanic Field; Is the ‘Big One’ Next?

Two back to back M4.8 earthquakes have struck the dormant volcanic fields near Big Pine, California.  (One event now downgraded to M4.3)

The earthquakes struck very close to Crater Mountain Volcano.

Obviously, two back to back M4.8 earthquakes at a dormant volcano is something that should even raise the eyebrows of a Geologist with a stone face.

This amount of activity, occurring at multiple California dormant volcanoes, is worthy to pay attention to, and (in the past) has been a sign of building pressure in the region — a sign of a coming larger earthquake in a nearby area along the coast.

Crater Mountain has almost ZERO information readily available online, rather we see articles turning up which speak of new findings regarding the age of the eruptions in the Big Pine Volcanic Field(s).

The best I can tell from the date ranges available, these volcanoes have not erupted in well over 15,000+ years..

One day ago, Mammoth Mountain / Long Valley Volcanic caldera was struck by multiple earthquakes.

Here is the full post on the dormant volcanic location in Central-Eastern California being struck yesterday (Feb. 15):

Normally, we see the dormant volcanic locations along the California / Nevada border show activity BEFORE we see movement occur off the West coast out to Sea.

Normally, the inland volcanic earthquakes are 1 magnitude LESS than the coming event off the coast.

The pressure coming from off the West coast is pushing the locations to the East, causing larger releases at the dormant volcanoes along the CA / NV border region.
