An area near Yellowstone National Park has been struck by nearly a dozen earthquakes on Friday, according to the US Geological Survey.
West Yellowstone in Montana reported around eleven earthquakes on Friday, with the strongest one measuring a magnitude of 3.1. The area has been hit by an additional 34 quakes in the past month, according to Idaho Statesman.
he other quakes ranged between 1.6 to 3.1 magnitudes and were about three miles (4.8 km) deep.
A swarm of earthquakes is not unusual for the area. Yellowstone is one of the most seismically active places in the US, experiencing around 700 to 3,000 earthquakes every year, according to the national park’s website.
The earthquakes tend to occur in clusters. The largest occurred in 1985 when more than 3,000 earthquakes were recorded in three months on the northwest side of the park.
The park is also well-known for its supervolcano. The US only has two supervolcanos: one at Yellowstone and another at Long Valley in California.
The Yellowstone one is measure about 34 by 45 miles (54 by 72 kilometres), and is as little as three miles (4.8 kilometres) below the surface.
