MAMMOTH, Wyo. – Yellowstone National Park's oldest and hottest geothermal area, a favorite spot for park visitors, was shaken by a moderate earthquake Tuesday evening. The U.S. Geological Survey ...
Things are getting hotter than a Dutton family feud. Yellowstone National Park, known for erupting geysers like Old Faithful, is home to one of earth’s largest volcanic systems, with the ...
Yellowstone is one of the planet's largest volcanic systems, a place where a plume of the Earth's molten core rises up through the solid rock of crust, heating and melting it to form reservoirs of ...
According to the USGS, "ShakeMaps provide near-real-time maps of ground motion and shaking intensity following significant earthquakes. These maps are used by federal, state, and local organizations, both public and private, for post-earthquake response and recovery, public and scientific information, as well as for preparedness exercises and ...
The Cascadia subduction zone is capable of producing megathrust earthquakes on the order of MW 9.0. Due to the relative plate motions, the triple junction has been migrating northwards for the past 25–30 million years, and assuming rigid plates, the geometry requires that a void, called slab window , develop southeast of the MTJ.

This brisk and robust seismic activity is common in volcanic areas, such as Long Valley Caldera near Mammoth Lakes, and Yellowstone Caldera at Yellowstone. The Coso Volcanic Field shows examples of volcanic activity, probably last active 30,000 to 40,000 years ago, but ash emission and small cone building episodes may be Holocene (>10,000 years ...
Similar blasts have happened in Biscuit Basin in 2009, 1991 and after the magnitude 7.2 Hebgen Lake earthquake 40 miles (64 kilometers) away in 1959. Yellowstone is centered on a huge, dormant ...
Further research shows that very distant earthquakes reach and have effects upon the activities at Yellowstone, such as the 1992 7.3 magnitude Landers earthquake in California's Mojave Desert that triggered a swarm of quakes from more than 800 miles (1,300 km) away, and the 2002 7.9 magnitude Denali fault earthquake 2,000 miles (3,200 km) away ...
