I believe that there is this "kind" of work going on at Cloverdale,
California with the geothermal drilling causing similar sized quakes and in
similar frequencies. I believe the largest event in our geothermal sequences
reached M4.5? The activity fluctuates over time but it's the usual cluster
on the weekly USGS maps.

Am I the only one concerned by the oil company drilling? Isn't this more
serious than surface coal mine blasting?
