Hebgen lake is the location of the largest earthquake to strike the Intermountain West in recorded history, with a M7.5 showing up in 1959.

The swarm is being caused by pressure coming from the West coast.  No doubt the pressure is building off the coast, now pushing the craton edge to the East, causing a swarm at Yellowstone as a result of the pressure.
