A series of earthquakes are currently shaking the Mammoth Lakes region of Eastern California.
Seismic activity began with the M5.2 earthquake, which was felt in parts of the Central Valley and in the San Francisco Bay area.
A series of aftershocks followed, including M4.6 and M4.1. A minor shock was recorded in wide parts of California (from Fresno to Sacramento) and Eastern Nevada.
No injuries or damage were reported.
Both the long Valley caldera and Mammoth Mountain have experienced episodes of increased unrest over the past few decades (earthquakes, soil elevation, and / or volcanic gas emissions).
The most recent activity in the area was about 300 years ago in Lake Mono.
Earthquake expert Lucy Jones said: “The current cluster of earthquakes east of Lake Mono is an area in which there have sometimes been very energetic sequences with a few larger events, so we won’t be surprised by new events today.
“In 1915 and 1954 there were M ~ 7 events north of here. Fortunately, most of the faults are far from cities. ”
Are these signs of an approaching geological disaster in California?
