Crater Lake (Mt. Mazama) had a small micro swarm of earthquakes this week lasting about 8 hours. These were very weak quakes, < 0.1 in magnitude, and nothing to be concerned about. It's considered normal background activity for volcanic regions.
However in 7 years of watching the webicorders for volcanoes, this is the first event like this I have noted at Crater Lake, so posting about it.
Also attaching the webicorder images for a permanent record here.
