Yellowstone National Park showed unprecedented seismic activity in July 2021, the largest since July 2017, when more than 1,100 earthquakes were recorded at the site. Fortunately, this does not mean an eruption of a volcano.
Under Yellowstone National Park is a dormant volcano that last erupted about 70,000 years ago. Frequent earthquakes in the area are caused by the mutual distance of fault lines and the movement of magma, water and gas below the surface.
The largest seismic activity occurred in 2017, when at least 1,100 earthquakes were recorded. The United States Geological Survey (USGS) said more than a thousand earthquakes were recorded here in June this year as well.
Fortunately, these earthquakes detected by the University of Utah seismographic station were not strong. It was perceptible, but did no damage. Only three reached magnitude 3.
A total of 1,008 earthquakes were recorded in seven swarms. The most tremors were recorded on July 16, 2021. The number climbed to 764, including one with a magnitude of 3.6 magnitude, the strongest that day.
According to experts, these events do not indicate an impending eruption. “Although this seismic activity is above average and unparalleled, it does not reflect magmatic activity. If the cause of the earthquake was magmatic activity, we would expect other indicators, such as heat and gas emissions. No such differences were found, “says the USGS report.
