Over the past 24 hours there have been a series of earthquakes which developed directly at (or very close to) multiple dormant volcanoes in California, and Nevada.

Northern California has now seen seismic activity very close toMount Lassen volcano, with a M3.0 earthquake striking next to a chain of smaller nearby volcanic buttes.
The screenshots below show the volcanoes nearby this current earthquake epicenter.  Places with names like “Black Butte” and “Tuscan Buttes” within just a few miles where the earthquake struck.

Further South in California, just across the border in Baja Mexico (Gulf of California), another series of dormant buttes showed seismic activity in the same few hours time.

Just like the volcanoes in Northern California, these smaller buttes are part of a greater volcanic complex.  In this case, in Mexico, we see the giant dome of a very old “super-volcano” located in Baja Mexico.

As with other large volcanic complexes, in Baja Mexico there are smaller nearby cones, and buttes which show signs of recent eruption in the past several hundred years.

As the aforementioned earthquakes were striking the dormant volcanoes in California, we saw a new swarm of earthquakes develop at dormant volcanic buttes located near Las Vegas, Nevada.
This Las Vegas movement began earlier this week with a noteworthy swarm of earthquakes, the largest of which was a 5.4 magnitude (4.8M revised) event North of Lake Mead which struck directly at an ancient volcanic butte.
As you can see in the screenshots below, the presence of small volcanic buttes near the recent Las Vegas Nevada earthquake epicenter indicates this seismic unrest is related to greater movement in the region, and is a sign of something to watch as a gauge for larger earthquake unrest to possibly come in the near term.
