Yesterday, an unusually strong earthquake swarm beneath the Pacific Northwest's most potentially dangerous volcano; Mount Rainier. This earthquake swarm is still ongoing, so far involving hundreds of events, causing people to wonder what exactly is causing these events and if there are any signs of volcanic unrest. Today's video will discuss the ongoing swarm at Mount Rainier via the opinion and analysis of a geologist.
