I suppose it depends what you define as a 'number' of small earthquakes. You can't really count before the 15th as there was only 1 on the 14th and
2 on the 13th.
This is based on delta=44.735,-111.13,0,5 in the ANSS catalog. The latitude and longitude are a mid point between what is currently seen in Google
earth USGS quakes and at 5 km radius pretty much encompases those and almost out to West Yellowstone.
Does not qualify as a swarm in my humble opinion.
Edit: As a comparison there were in excess of 100 per day in the Dec/Jan swarm.
