At approximately 6:00 p.m. MST on Tuesday, January 28, 2025, Yellowstone National Park experienced a magnitude 3.9 earthquake near the Norris Geyser Basin.
This tremor, the most significant in the park since March 2023, was felt by at least 33 individuals within a 30-mile radius. Folks reported sensations ranging from weak to very light shaking.
It happens
Yellowstone is no stranger to seismic activity, with thousands of minor quakes occurring annually. However, a magnitude 3.9 event stands out.
Yellowstone National Park is situated atop a vast volcanic system, leading to frequent minor earthquakes. Larger quakes, such as the 7.3 magnitude Hebgen Lake earthquake in 1959, are rare but have historically caused significant changes in the park’s geothermal features.
Norris Geyser Basin location
The recent earthquake’s proximity to the Norris Geyser Basin, Yellowstone’s oldest and hottest geothermal area, is noteworthy. This area is known for its dynamic geothermal activity, and seismic events can influence geyser eruptions and hot spring behaviors.
Despite the quake’s strength, there have been no immediate reports of significant changes to the basin’s geothermal features.
Closely monitored
It’s important to understand that while such earthquakes can be startling, they are a natural aspect of Yellowstone’s geology. The U.S. Geological Survey monitors these events closely. The current data indicates that this earthquake is typical for the region and not indicative of increased volcanic unrest.
No cause for alarm
Park officials advised that visitors and residents should remain informed but not alarmed, as these events are a natural part of the park’s dynamic geological environment.

Great report Gail! Wish I’d been in the area to experience the ground shakers!
Thank you for the news, Gail, and passing along the assurance that the park is no less safe now than before the earthquake. Have a great weekend and safe travels!
