Most recently, a devastating Mw 7.3 (Ms7.5) earthquake in 1959 killed 28 people and caused $11 million in damage (1959 dollars). Geographic Names Information System (GNIS), Mapping, Remote Sensing, and Geospatial Data, 60 years since the 1959 M7.3 Hebgen Lake earthquake: its history and effects on the Yellowstone region. Yellowstone’s Earthquake Threat Y ellowstone has experienced the largest historical earthquake in the Intermountain West in the 1959 M W 7.3 Hebgen Lake earthquake.

Geologists conclude that large earthquakeslike the Hebgen Lake event are unlikely within the Yellowstone Caldera itself, because subsurface temperatures there are high, weakening the bedrock and making it less able to rupture. It's when earthquakes reach magnitudes between 2.5 and 5.4 that activity is usually felt, with minor resulting damage. At 11:37 p.m. a 7.3 magnitude earthquake devastated Hebgen Lake, Montana, located in Yellowstone’s northwestern region—in comparison, the 2010 earthquake in Haiti registered at a 7.0 magnitude.

The recent cluster of quakes didn't pass 3.0 magnitude. While none of them were particularly large (the largest being around 2.9 on the Richter scale), it does represent a slightly larger than average number of earthquakes in the Yellowstone caldera, which is famous for its tempestuous seismic activity. Although rising magma and hot-ground-water movement cause some earthquakes, many occur as the result of Basin and Range extension of the western U.S. It was initiated by a M4.1 earthquake which was followed by more than 800 aftershocks. Earthquake damage from the 1959 Hebgen Lake event in the Yellowstone Plateau.

These earthquakes are caused by tectonic extension of the region and are not related to Yellowstone, nor will they have a significant impact on the Yellowstone system. The 2008–2009 swarm began on December 27, 2008, in northern Yellowstone Lake and lasted for around 11 days until January 7, 2009, migrating north over time at about 1 km per day. googletag.cmd.push(function() { googletag.display('div-gpt-ad-1449240174198-2'); }); Although the area is one of the most seismically active regions in the U.S., the cluster of quakes "is on the large side in terms of number and magnitude, but nowhere near the largest," Michael Poland, scientist-in-charge at the Yellowstone Volcano Observatory, told McClatchy News in an email.

On August 17, 1959, the Hebgen Lake Earthquake, measuring 7.5 on the Richter scale, triggered a massive landslide that moved at 100 miles per hour. Earthquakes cannot be predicted yet, but modern surveillance conducted with seismographs (instruments that measure earthquake locations and magnitudes) and Global Positioning System (GPS) instruments that measure slow ground movements help scientists understand the state of stress in the Earth's crust that could trigger earthquakes as well as magma movement. Centered near Hebgen Lake, just west of the park, it had a magnitude of 7.5. According to preliminary data, the quake … To the south of Boise and Yellowstone, Salt Lake City has also seen a large number of earthquakes in the last few weeks. In 1871, Ferdinand V.
