One of five seismometers around Mt. Shasta this morning, measuring 24 hours of bumps and thumps, produced this seismogram.

  2. The entire Pacific "Ring of Fire" has been acting up lately. I read recently where there were almost 700 earthquakes of 4.0 magnitude or better in a very short period of time.

  6. Looking at the bright side, if Shasta does blow CW will have a great view of it.

    1. I'll report here until the very end. Mrs. CW will be long gone southward by then.

    4. I'm about sixty air miles away. I'll probably be fine. Probably.

  7. Why does the USGS website show absolutely nothing for the Shasta area? And I have it set to show ALL magnitudes. Some 0.1 showing elsewhere.

    2. USGS reported a 5.9 quake near Dayton, Nevada a couple of weeks ago and almost immediately said "Ooops. False alarm. Sorry about that."

    3. Well, their earthquake map shows NOTHING. And currently that link is timing out.

  8. I was at Cal Tech in the seismograph room. Just then a 3.4 Richter for the area was recorded.
    The Director said, Oh, that's just a dump truck rumbling by. The university was having site work for a new building.

  9. I would check for avalanches coinciding with seismograph recordings.
