Yellowstone volcano rocked by 1,700 earthquakes as fears of an 'overdue eruption' persist


Ground deformation rates were also well within the norm last year, with the Yellowstone caldera subsiding by about one inch per year – as it has been doing since 2015.

The USGS report reads: “Earthquakes have been monitored in the Yellowstone area since the 1970s.

“The Yellowstone Seismic Network is maintained and operated by the University of Utah Seismograph Stations, which records data from 46 stations in the Yellowstone region.

“On average, about 1,500 to 2,500 earthquakes are located in and around Yellowstone National Park every year (most of which are too small to be felt by humans), making the Yellowstone region one of the most seismically active areas in the United States.”
