Earthquakes

Answers to questions about monitoring at Yellowstone.

The Yellowstone region is one of the most seismically active areas in the United States. It experiences an average of around 1,500 to 2,500 located earthquakes per year! The majority of these earthquakes are too small to be felt by humans but are detected by a sophisticated network of about 50 seismometers called the Yellowstone Seismic Network (YSN).

The Yellowstone Plateau Volcanic Field forms the high continental divide between the northern and middle Rocky Mountains.

From 1,500 to 2,500 earthquakes typically occur each year within Yellowstone National Park and its immediate surroundings.
