The notable swarm of earthquakes that started December 26, 2008, beneath Yellowstone Lake in Yellowstone National Park has stopped for now and may have ceased entirely.

This sequence of more than 500 seismic events was most intense on December 27, 2008. The sequence included sixteen events of magnitude 3 to 3.9 and approximately 70 of magnitude 2 to 3 (as of Sunday afternoon, Jan. 4, 2009). Visitors and National Park Service employees in the Yellowstone Lake area reported feeling the largest of these earthquakes.

No damage was reported within Yellowstone National Park. The swarm was in an area of historic earthquake activity and was close to areas of hydrothermal activity on the lake floor. Similar large earthquake swarms have occurred in the past at Yellowstone, without triggering steam explosions or volcanic activity.
