Volcanic Earthquakes

I woke up this morning to several alerts from my Earthquake app because of nearby seismic activity at Mt Hood... I only get alerts with 2.0+ magnitude shakers so this was significant. Mt Hood is understood to be dormant so it's perplexing that there is a swarm happening. Perhaps it is related to the nearby Mt St Helens swarm? There has also been sightly elevated seismic activity near Mt Rainier over the past couple of months. 

From Wikipedia:

Mount Hood is considered the Oregon volcano most likely to erupt,^[9] though based on its history, an explosive eruption is unlikely. Still, the odds of an eruption in the next 30 years are estimated at between 3 and 7 percent, so the U.S. Geological Survey (USGS) characterizes it as "potentially active", but the mountain is informally considered dormant.

 Magma chambers must be filling up and one of these volcanoes might have a little eruption at some point in the near future!
