Hi Canie. That area does indeed have quakes in the M=3.0+ range. They don’t have them everyday, but they do get them. This most recent quake is about 12 miles north of the December 2000 swarm. In 1984 there was a swarm at Stout's Meadow, which is located to the north of the most recent quake.

You’re right about volcanics in the area. You can’t walk anywhere without walking on lava. It is all over the place. The crust in this area is judged to be thin so anytime there are quake swarms in the area the first thought that comes to mind is that it is related to a volcano. The 2000 swarm was judged to be tectonic, but the fault that caused the quakes has never really been identified. There are 3 unnamed faults in the area so the quakes could have been associated with any one of them. Take Care…Don in creepy town
