The US Yellowstone National Park, known for its wildlife and active volcano, has been hit by a wave of earthquakes. On Thursday, September 10, the Geological Survey of the country recorded more than 90 tremors in the reserve.

The maximum activity of vibrations of the earth's surface was recorded in the area from the south-west of Lake Yellowstone between the Hart reservoir and the West Finger. This region is one of the most dangerous in terms of seismicity. The earthquake cluster here is striking in the number and strength of the tremors, but it is not the largest. The fluctuations recorded the other day did not exceed 3 points. The maximum magnitude was 2.8, and the minimum was 0.1. Damage to surface and infrastructure typically begins at 2.5 activity. With this indicator, they are insignificant. However, tremors in the park quite often destroy highways, turning them like a spider web.
By the way, the maximum seismic activity in Yellowstone was recorded in 2017. Then, for almost 3 months, about 2,400 earthquakes with a maximum magnitude of 4.4 points occurred in the reserve.
