Well - since we're speculating.... It appears that a lot of those locations are geothermal - Mammoth hasn't really stopped shaking since that qukae in Alaska. That Viola swarm is right in there by Redding and Lassen. The Geysers are very busy as well.

Now it looks as if all those fluids down there don't want to stay quiet.

There are a few outside the geothermal areas - San Juan Bautista is creeping along. Actvity outside geothermal areas appears to be 'normal'.

Has anyone been looking at other areas of the Cascades to see if any of this activity is going on in that region?
