There’s something oddly beautiful about this. I’ve been on earthquake watch at Yellowstone during the past week. They had a big swarm of quakes in the 2.5+ range over the past ten days or so–enough to get many seismologist’s attention. They’ve centered under Yellowstone Lake, and have slackened off a bit now. I wonder if any animals noticed the shaking. Some of the quakes were felt by park officials and winter visitors.
