[Geysers] Earthquakes near OF

[Graham Meech]

Looking at the University of Utah site I see there have been 28 small
earthquakes about 8 miles from Old Faithful between 2323 on 2/21 and 1500 on
2/22 ranging from magnitude 0.2 to 2.0.

The ones stronger than magnitude 1 also show up well on the OF seismogram
(although it goes rather wild later on the 22nd):

I wonder if there are any geyser changes?  Are these earthquakes too small
to cause any changes even though they are close by?

 

Maybe the OF webcam stopping and restarting is related to this too.  I am
glad to see that OF is still active.
