Yellowstone Supervolcano’s Unusual Activity Might Be a Sign of Eruption

Yellowstone supervolcano encountered a large amount of 222 earthquakes last month, including three massive swarm events. Could this seismic activity hint at a future eruption? Geologists decided to take a closer look at Yellowstone volcano, stationing around the Yellowstone National Park, in the US.

The unusual activity might indicate a lot of theories, but the fact that the the volcano might wake up from its deep sleep scares everyone. The last massive eruption occurred almost 640,000 years ago. Many fears already that it’s only a matter of time until another destructive eruption.

Last month, researchers from the USGS (US Geological Survey) recorded a massive amount of 222 earthquakes in the Yellowstone area. Four eruptions of the Steamboat Geyser on February 1, 12,21, and 28 followed the tremors.

USGS stated: “The largest event was a minor earthquake of magnitude 2.4 located 2.5 miles northeast of Lake, in Yellowstone National Park, on February 10 at 6.14 am MST.” All those small tremors might signal for a Yellowstone eruption.

During such a period of seismic activity, the USGS also recorded three earthquake masses on three different periods. The most powerful, however, erupted between February 17 and February 24 and comprised 68 earthquakes. They all ranged in magnitude from -0,4 to 2,1, and the massive was encountered on February 20.

A second mass erupted on February 11 and the following day, as well, and 38 tremors were recorded. The swarm hit almost 15 miles south-southeast of Old Faithful in the Yellowstone National Park area. The earthquakes all struck magnitudes between 0,6 and 2,3.

Only 12 small tremors were recorded between February 3 and February 4. However, according to USGS, the mass only struck some magnitudes of -0,1 and 1,2 only north-northwest of West Yellowstone in Montana.

“Earthquake sequences like these are common and account for roughly 50 % of the total seismicity in the Yellowstone region. Yellowstone earthquake activity remains at background levels,” explained USGS.
