(Meredith) -- Since June 12, seismologists have been recording more than 2,000 earthquakes in the western region of Yellowstone National Park, according to a new report published by Newsweek. The latest data puts this ongoing event as the biggest swarm recorded to-date.

According to the USGS, scientists say the swarm does not signal an impending eruption from Yellowstone's supervolcano, but the event is "fascinating" and needs to be studied further. 

In a monthly update from Yellowstone, the USGS said 115 earthquakes had been reported in September. Of these, more than 70 were part of the ongoing swarm just six miles north of West Yellowstone. The biggest event in the swarm was registered as a magnitude 2.3.

“Including the events from the prior three monthly reports beginning on June 12, total swarm seismicity includes one earthquake of magnitude 4.4, 12 in the magnitude 3 range, and 185 earthquakes in the magnitude 2 range,” the statement said.

According to Newsweek, earthquake swarms account for about half of the seismic activity at Yellowstone. These earthquake swarms happen when many mini-quakes occur in close succession of one another. The report goes on to say that scientists believe the swarm may be coming to an end.

One seismologist told Newsweek much analysis will be done to understand what causes earthquake swarms and what they may mean for the park's supervolcano.
