The U.S. Geological Survey (USGS) shared its monthly report on earthquake activity Monday. It says seismologists reported more than 1,000 minor quakes around the Yellowstone National Park last month.
It is the most quakes reported at the national park since June 2017.
Most of the tremors were a part of seven different swarms. A swarm is a series of small quakes that happen back to back for a short period.
The Agency says the largest swarm saw more than 764 earthquakes hit beneath Yellowstone lake.
