The Yellowstone region was hit by around 1,000 more earthquakes in 2021 compared to the previous year, according to a new report.
This week, the United States Geological Survey's (USGS) Yellowstone Volcano Observatory (YVO) released its 2021 annual report, which documents volcanic and hydrothermal activity in the region over the past year.
The report identified 2,773 earthquakes in the region in 2021. While this is much higher than than the 1,722 quakes that were recorded in 2020, it is not significantly outside the historical average of about 1,500-2,500 earthquakes per year in and around Yellowstone National Park.
Earthquakes have been monitored in the Yellowstone region since the 1970s, with a network of seismographs in the region—maintained by the University of Utah—monitoring activity.
The Yellowstone region is one of the most seismically active areas in the United States. Since 1973, there have been more than 50,000 earthquakes in the region, although the vast majority are too small to be felt by humans.
