No earthquake but interesting article by Forbes....

240 Cubic Miles Of Magma Was Just Discovered Beneath California's Supervolcano

One of the largest supervolcanoes in the world sits underneath California, lying dormant for the past 100,000 years. Now, researchers have gotten a clearer glimpse into what lies below the Long Valley supervolcano, uncovering 240 cubic miles of magma sitting beneath California.

It's important to start off by saying this absolutely doesn't mean there is any imminent danger. Experts at the United States Geological Society (USGS) are actively monitoring the supervolcano, and while there has been an uptick in activity over the past four decades, there are no signs of an eruption.
