Yellowstone Quake Swarm Update 8

Things seem to be quieter this evening, perhaps following a pattern that has been ongoing since the swarm began - very active periods followed by calm periods.  We'll see if things get busy again by morning.  In the meantime, there was finally an update from Dr. Smith, reported by

"By Friday, January 2nd, Smith said over 500 tremors had been recorded around the north end of Yellowstone Lake. The biggest quake was a magnitude 3.9 - not big enough to cause damage. “This is a big deal”, said Smith, who has been studying the volcanic and geothermal activity at Yellowstone for over 30 years. There have been clusters, or “swarms” of quakes at Yellowstone before, but not this many for this long says Smith. “What’s important about them is that this is not normal, not usual to have these longer swarms so we pay particular scientific attention to them in terms of how they might relate to faults or to geysers or other hydrothermal features,” said Smith.
