So something changed deep beneath Mount Shasta today


The normal pattern of the seismograph on the north west corner of the mountain, nearest Shastina, switched from heartbeat like thumps to this.


Little rumbles, then quiet, and finally a long, sustained screech that petered out at the bottom of the graph.

Odd.  Seems like sustained movement of something underground.


Again, the seismograph to the east echoed this, but more faintly, with some bumps along the way.

I think I'll keep an eye on this.  Interesting change.

The seismograph is located about halfway from the summit to the top of the picture.

  3. From Wikipedia: "During the last 10,000 years, Mount Shasta has erupted an average of every 800 years, but in the past 4,500 years the volcano has erupted an average of every 600 years. The last significant eruption on Mount Shasta may have occurred about two centuries ago."

    So another eruption maybe isn't likely- but I'd have my bugout bag packed just in case!

  4. Maybe all this seismic activity means California will soon become an island...too bad it's not confined to the lower half.
