The latest from Yellowstone’s supervolcano: a ‘intensifying’ seismic swarm has extended beneath the lake.
YELLOWSTONE LAKE has been shaken by a large “intensifying” earthquake swarm, but USGS experts say there’s nothing to worry about.
The Yellowstone supervolcano has been rocked by a 3.1-magnitude earthquake. In less than 24 hours, more than 140 earthquakes were recorded beneath Lake Yellowstone. The USGS warned that earthquake swarms were “frequent” and that the public should not be concerned.
Some individuals, however, believe that earthquakes in Yellowstone are an indication that the supervolcano beneath the park is about to erupt.
“Earthquake sequences like these are typical and account for nearly half of the total seismicity in the Yellowstone region,” the USGS tweeted.
“This swarm is identical to one that happened in the same area around the same time in December 2020.”
There were 40 earthquakes larger than magnitude-2 and two incidents in the magnitude-3 range in this swarm.
Seismic activity in this volcanic area has increased in recent weeks.
June was an extremely active month for earthquakes, according to USGS geologists.
During the month, Yellowstone recorded 445 earthquakes, more than double the monthly normal of 100 to 200 earthquakes.
Officials underlined, however, that the recent activity is not alarming.
“While above average for a month, this is by no means unprecedented,” the USGS noted.
Officials believe it will be thousands of years before Yellowstone erupts.
The Yellowstone Volcano Observatory’s alert level is green, which is normal.
“Some swarms are generated by slow fault slip that triggers earthquakes on a few sticky places of the fault,” the USGS noted of the latest activity.
“Magma-filled fissures push their way through the crust, causing more swarms to form.”
MrMBB333, a YouTube channel dedicated to Yellowstone earthquakes, expressed concern that the “intensity of these swarms in the center of Yellowstone supervolcano lake is intensifying over time.”
“A 3.1-magnitude earthquake is not a particularly large earthquake in terms of size, but its position is significant,” he noted.
