U.S. seismic hazard zones awaken: Long Valley super-volcano earthquake swarm notice

August 24, 2011MAMMOTH LAKES, Calif. – Long Valley Caldera – While the East Coast recovers from earthquake jitters, small quakes have been rocking California. A minor jolt struck the San Francisco Bay area Wednesday at 9:57 a.m., just hours after a similar temblor hit the same spot late Tuesday night. The U.S. Geological Survey says both magnitude- 3.6 quakes were centered about six miles southeast of Oakland along the Hayward fault, a major Northern California fault zone. The Sierra Nevada high country was also rattled by an earthquake early Wednesday. The USGS says a magnitude- 4.4 quake hit at 4:59 a.m. about nine miles southeast of Mammoth Lakes. A Mono County sheriff’s dispatcher says authorities have had no reports of damage. A magnitude-5.8 quake jolted much of the eastern United States on Tuesday. –Sac Bee  The map on the left is the blast radius of any potential large-scale eruption at the Long Valley caldera.

    could these swarms be related to the CO quake?

    Hello Alvin,
    I was wondering where to find a link to a website that shows the increase in volcanic activity in 2011 verses previous years. It seems like every day, a new dormant volcano has come back to life.

    I want to thank you for all of your tireless research to find and share the news stories that the national media refuses to air. May God bless you and your family. I know the chance of us meeting here on earth is pretty slim but I hope to make your acquaintance one day soon, up in the air, on our way to meet Jesus in the sky!

    Be blessed!
    Pia

    • I’m going to leave that open and see if someone could suggest a site for you Pia…

      Thank you for the kind words and it would be a pleasure to meet you on any occassion, especially the one you mentioned.

      God bless,
      Alvin

    Here soon when the quakes increase in magnitude and are happening consistently and the volcanoes start erupting then people will take notice to what is happening on a global scale. But just knowing that and acknowledging what is happening is not going to save everyone. Where can you run and hide when the whole planet starts to unravel?? This is why we are spiritual beings. It’s knowing and believing that there is more to life than this physical body we inhabit and this 3D universe we live in. Pray and do not pray that God be on your side. However, pray that you are on God’s side. I wish and pray nothing but the best for the human race but it would appear that someone else has different plans for us all.

    Alvin, what’s the long valley caldera? Never heard of that one.

  6. Bone Idle says:

    The Long Valley area has been seismologically active for years – often 10 or more small events per day. It’s one of the U.S.G.S’s watch points. It has quietened down in the last 10 months. Seems to have woken up again. There was major uplift for years which quietened down. There was flora dieoff due to CO2 leaks in one area.

    The USGS has a likely table for “The BIG One”. I wonder with last weeks events around the US the likely table has been adjusted.

    Pia, this isn’t what you are looking for, nevertheless it is very informative. I am sure I have seen what you are looking for. Just have to find it.

    Pia, I found this link with graphs covering earthquakes, volcanoes, tsunamis and solar with possible estimates to 2016.

    If you google CATDAT volcanoes there is an indepth data base for 2010.

    Long Valley seems to be more ‘active’ than Yellowstone is, and is probably more dangerous, in that regard.
