YELLOWSTONE volcano’s ground is slowly creeping upward around its most active geyser basin, USGS officials have revealed after seismographs have confirmed more than 120 earthquakes across Yellowstone Park.

officials are paying attention to an ongoing shift in the supervolcano’s landscape, which began as early as 2015. Yellowstone’s Norris Geyser Basin, Yellowstone’s hottest geyser basin, witnessed ground levels rise by almost an inch last year. Officials from the United States Geological Survey (USGS) confirmed in the latest Yellowstone activity update, the basin rose by 0.78 inches (2cm) in 2018. GPS data collected throughout the Yellowstone volcanic caldera suggests this part of the national park has been rising for at least three years now.

In the same Yellowstone update, the USGS revealed a total of 121 earthquakes were recorded in the Yellowstone area in December 2018 alone.

The earthquakes struck in rapid swarms and singular tremors throughout the park.

At least 50 percent of all recorded seismic activity in Yellowstone was attributed to earthquake swarms.

The strongest Yellowstone earthquake of magnitude 3.1 was detected in late December last year.
