Swarm of Earthquakes Hits Near Long Valley Volcano, California – M4.4 Near Toms Place Felt Across Western Sierra Nevada and Central Valley


A M4.4 earthquake followed by 9 other tremors rattled parts of central and eastern California Saturday morning.

The quakes are all situated 8 miles away from the Long Valley Volcano.

The strongest quake of the series hit around 10:30 a.m. about 8 miles west-northwest of Toms Place in Mono County.

Strong to moderate shaking was felt near the epicenter, while weak to light shaking was reported across the western Sierra Nevada and Central Valley by over 600 people on the USGS homepage.

All quakes hit between 10km and 8km depth and are situated about 6.8 miles from the Long Valley Volcano:

The California Governor’s Office of Emergency Services reported no initial reports of injuries or damage.

Toms Place is situated near the thermally active Long Valley Caldera and Mammoth Mountain volcanic system. And some California geologists are wondering if it is waking up:

As shown in my 2018 article, the Long Valley supervolcano in California has a huge reservoir of semi-molten magma measuring an amazing 240 cubic miles.

And that quantity of magma could support an eruption equivalent to the massive one which occurred 767,000 years ago, which released 140 cubic miles of material into the atmosphere.

Just for comparison, the 1980 Mount St Helens eruption resulted in the release of 0.29 cubic miles.

  1. yes TRN every one thinks FEMA of any nations . No one will be there to help you accept yourself. See China is not using bullets since expensive and they kill them alive by putting them in Holocaust like NAZI Germany? Still FEMA has not paid the people of New Orleans yet? What do you except them give you ZYVOX to Kill the Corona virus. In Canada we have many Chinese in Vancouver Canada BC and we all afraid now. When a Chinese passes by me of course i am in high gears. Many not yet in Canada?

  2. I told people of Northwest of Canada till San Diego needs to prepare. But still people doing same thing smoke and Vodka? Buy foods and Masks
    and prepare your relatives. What happens when you are driving and Martial Law starts. Do you know how to get to loved ones?

    • Those are the ones who always believe that it’s the government’s responsibility to take care of them, we know what that leads to.
