“Yellowstone earthquake activity remains at background levels.”
The USGS also recorded three eruptions of the Steamboat Geyser in Norris Geyser Basin during this period.
The geyser erupted on March 6, March 15 and March 25, for a total of nine eruptions so far this year.
The USGS has also assured the recent earthquake in Idaho is not a sign of any volcanic stirring in Yellowstone.
The agency said: “It’s been an eventful month for seismic activity in the western USA, with a M5.7 earthquake near Salt Lake City, Utah, on March 18, and a M6.5 in central Idaho on March 31.
