Mt St Helens

Reports of a small Earthquake swarm not far from Mt St Helens south of the border are coming in. Whether this develops further is on my list of things to watch. The swarm itself is reported at around approximately 2-5 kilometres depth. This sort of tremor activity is generally thought not to be indicative of eruption, just a little bit of subsurface rearranging of geological furniture.

Iceland is pretty quiet at the moment, seismically speaking. Considering where it sits on the mid Atlantic spreading zone, this is mildly surprising. However, I'm sure another swarm will be along in the next few days.
