Yellowstone Earthquake Swarm Observed by PBO Strain and Seismic Network


Beginning Jan 17th, 2010 at about 1:00 PM (MST) a significant swarm of earthquakes started in the Yellowstone area located about 16 km northwest of Old Faithful. According to the Yellowstone Volcano Observatory (YVO), “swarms have occurred in this area several times over the past two decades.” As of Feb 5th, 2010 there have been 1778 recorded events, with the largest single event having a magnitude of 3.8 and the cumulative magnitude of the swarm near magnitude 4.4.

The PBO seismic and strain networks were utilized for real-time earthquake location and hazard assessment. Daily reports were produced by PBO staff for the YVO (and the Incident Command) to be used in their assessment of safety issues.
