YVO mentions in their post that this swarm is in area currently in the midst of an uplifting episod….which has some similarity to past events in 1996 and 2003.

A snippet from the USGS report:
“Today’s event is the largest earthquake at Yellowstone since February 22, 1980, and occurred near the center of a region of recent ground uplift described in a YVO Information Statement on February 18, 2014. The Yellowstone Volcano Observatory has been tracking this uplift episode for about 7 months”. [link to volcanoes.usgs.gov]

“As discussed in the March 3, 2014 YVO Monthly Update, seismicity in the general region of the uplift has been elevated for several months. A previous period of uplift in this area occurred between 1996 and 2003, and it was also accompanied by elevated seismicity”.

While all this data is interesting, the general consensus is no big deal other than “normal” fluctuations in both uplift and related seismicity.
