5/31/2015 — Earthquake strikes Utah Dormant Volcano — 3.2M event at Markagunt Volcanic Plateau

A rare magnitude 3.2 earthquake has struck South Central Utah near the dormant Markagunt volcanic plateau.

The last eruption of this volcano was nearly 1,000 years ago. (1050AD – in the early middle ages / late dark age)

May 31, 2015 – Magnitude 3.2 earthquake strikes the Markagunt volcanic plateau in South Utah. The plateau is made up of multiple lava flows which extend from a cluster of long dormant volcanic cinder cones. The obvious volcanoes stand out easily, the more weathered flows to the North (near the earthquake epicenter) are much more eroded, and hard to differentiate from the surrounding mountains.



This earthquake in Utah (at a dormant volcano) immediately followed a 4.1 magnitude earthquake which struck at Salton Sea Volcano in Southern California near San Diego, CA.


The Salton Sea volcanic buttes are “active” as opposed to the long dormant Markagunt volcanoes.

For there to be two different earthquakes at two different volcanoes in the Southwest United states within about 2 hours time, this lets us know greater pressure is building on the West coast of the United States.

The greater craton pressure is putting stress on the magma chambers of a few (so far) Southwestern United States dormant volcanoes, also pressure showing up via a series of earthquakes at the fracking operation weak points in the midwest (Illinois + Kansas).

Keep watch for more activity, and at this point.. you better start looking up the coordinates of each earthquake above 3.0M on the West coast to see what resides at the location.

You can use the USGS coordinates from : http://earthquake.usgs.gov

Then use a full version of Google earth to look up the earthquake , download a copy of google earth here:  http://earth.google.com
