5/29/2015 — West coast seismic unrest at Dormant Volcanoes — California Volcano Peak

Things are on the move , seismically speaking.

An earthquake has struck Central Eastern California between Volcano Peak, and Volcano Butte, as well as near Mount Shasta volcano (directly at Trinity Lake Dam).

The screenshots below show the location of the earthquake epicenter in comparison to the nearby volcanic peaks.  Clearly these volcanoes have a long eruptive history.

Over the past week, we have seen an unprecedented number of dormant volcanoes show earthquake activity along the West coast of the United States.

Multiple noteworthy earthquakes have struck multiple dormant volcanoes in California, Nevada, Oregon, and Washington state.

We even saw a volcanic earthquake event reaching into the 5.0M+ range near Las Vegas Nevada (at a dormant Butte volcano), and another series of events in South California / Baja Mexico near a dormant volcanic butte as well.

Keep in mind, the United States (West coast in particular) is not immune from sudden unexpected eruptions.  As we just saw today in Japan, a large unexpected volcanic blast struck  just South of the Japanese mainland.

The Japanese are known for monitoring their volcanoes in a vigilant way, thus if a large unexpected eruption can happen to them, it can happen to the United States as well.

Currently we are in a state of major international unrest, where we are seeing multiple large unexpected volcanic eruptions, and multiple large earthquakes across vast regions, which means we need to be on watch for further large seismic developments in the Pacific.

With this much activity showing, including multiple large eruptions in the West Pacific, and multiple dormant volcanoes showing activity on the East Pacific (California, Mexico, Oregon, Nevada, Washington State) —– this means keep watch for more near term LARGER movement to follow in these regions.


Information on this earthquake from the USGS:

Magnitude/uncertainty 2.6 ml± 0.2

In addition to the above movement, a noteworthy 5.1 magnitude earthquake has struck Northern California near Mount Shasta volcano, directly at Trinity Lake Dam.

The Northern California earthquake directly followed an even larger 6.8M which struck just minutes before off the coast of Alaska.

The Alaska earthquake was just a few hours after a large unexpected volcanic blast from a volcano in South Japan. The Japan blast, the Alaska earthquake, and this California earthquake all occurred within less than 12 hours time.

A review of the surrounding area shows the earthquake in California is very close to Mount Shasta, and also the Lassen Volcanic center (seen with multiple dark lava flows to the East).

This activity is a sign of the greater unrest happening in the Pacific due to the “global unrest event” currently taking place across the planet.



USGS is NOT reporting this event for some reason:
