What was the largest earthquake in Yellowstone?
What was the largest earthquake in Yellowstone? The largest historic earthquake in the Rocky Mountains was a magnitude 7.3 earthquake at Hebgen Lake northwest of Yellowstone in 1959. It was caused by the extension--or stretching--of the Earth's crust. The earthquake displaced a 40-km-long fault (25 miles) that rose vertically up to 12 meters (40 feet).
What causes the most deaths in Yellowstone?
Drownings have resulted in five known deaths in the park. Looking at all national parks, the survey indicated that falls were by far the most common way to die, accounting for a total of 245 deaths.
How many earthquakes in Yellowstone in 2023?
During August 2023, the University of Utah Seismograph Stations, responsible for the operation and analysis of the Yellowstone Seismic Network, located 136 earthquakes in the Yellowstone National Park region.

How often has Yellowstone exploded?
Three extremely large explosive eruptions have occurred at Yellowstone in the past 2.1 million years with a recurrence interval of about 600,000 to 800,000 years. More frequent eruptions of basalt and rhyolite lava flows have occurred before and after the large caldera-forming events.
Could an earthquake trigger Yellowstone?
Not in any significant way. Large, distant earthquakes can cause changes to geysers and hot springs within Yellowstone because shaking fractures the fragile subsurface hot water plumbing systems. However, significant tectonic stresses are not transmitted very far.
How far would Yellowstone volcano reach?
The lava flows themselves would be contained within a relatively small radius within the park — say, 40 miles or so. In fact, only about one-third of the material would actually make it up into the atmosphere.
