[Geysers] Small Local Earthquakes

[Michael Goldberg]

It looks like there was a flurry of small earthquakes (largest was 2.9) 
overnight, about 5 km north of the Fountain Group and at various 
depths.

I recall that Gordon Bower had an approximate formula for predicting 
whether an earthquake might produce discernable effects on geyser 
activity.  I hope he'll re-post it here.  My first guess is that maybe 
some features in the Kaleidoscope Group would be affected (although 
things change so rapidly there anyway, how would you tell?) but the Upper
Basin would be to far away to expect any response.
