With 1,620 small earthquakes between January 17, 2010, and February 1, 2010, this swarm was the second-largest ever recorded in the Yellowstone Caldera. The largest of these shocks was a magnitude 3.8 that occurred on January 21, 2010.
44°26′N 110°40′W / 44.43°N 110.67°W / 44.43; -110.67. The Yellowstone hotspot is a volcanic hotspot in the United States responsible for large scale volcanism in Idaho, Montana, Nevada, Oregon, and Wyoming, formed as the North American tectonic plate moved over it. It formed the eastern Snake River Plain through a succession ...
A series of shallow earthquakes associated with the volcanic activity in Yellowstone struck this area in 1978. Soil temperatures increased to nearly 200 °F (93 °C). The slope between Sizzling Basin and Mud Geyser, once covered with green grass and trees, became a barren landscape of fallen trees known as "the cooking hillside".
Yellowstone National Park is known for its supervolcano and active geysers, but lidar technology is helping scientists better understand the threat of earthquakes for surrounding communities like ...

It measures seismic activity, deformations in the Earth's surface and low-frequency acoustic energy that could signal an eruption. ... Yellowstone encompasses the caldera of a huge, slumbering ...
Paraná and Etendeka traps, Brazil, Namibia and Angola form 128 to 138 million years ago. 132 million years ago, a possible supervolcanic eruption occurred, ejecting 8,600 cubic kilometers (2,063 cu mi). [90] Formation of the Karoo-Ferrar flood basalts begins 183 million years ago.
The 1959 Hebgen Lake earthquake (also known as the 1959 Yellowstone earthquake) [4] occurred in the western United States on August 17 at 11:37 pm (MST) in southwestern Montana. [4][5] The earthquake measured 7.2 on the moment magnitude scale, [1] caused a huge landslide, resulted in over 28 fatalities and left $ 11 million (equivalent to $115 ...
