Yellowstone Earthquake: Volcanic Eruption NOT Expected After Strongest Tremor in 29 Years

Yellowstone National Park was shaken by its largest earthquake in 29 years Sunday, but scientists say there is no concern that the quake will lead to an eruption of the Yellowstone Caldera, a supervolcano located in the park.

The magnitude-4.8 earthquake struck inside the park boundaries at 6:34 a.m. MDT Sunday. The epicenter was near the middle of the par, near the Norris Geyser Basin, according to Peter Cervelli of the U.S. Geological Survey.

The quake, the largest since another 4.8 tremor in 1985, was preceded by two foreshocks measuring 2.8 and 3.0 at 12:23 a.m. and 4:36 a.m. Sunday, respectively. The main shock was then followed by at least four aftershocks ranging in magnitude from 2.5 to 3.3 later Sunday morning.

There were no immediate reports of damage. There are few visitors in the park this time of year.

Cervelli said the earthquake is interesting scientifically because of the length of time since a quake of equal intensity. He added that data gathered from earthquakes give scientists great insight into volcanoes and tectonics.

However, Cervelli said there are no hazardous implications, and that the Yellowstone Caldera is not about to erupt.
