I could hear trees splitting and falling. It got terribly quiet, and then the screams began. Earthquakes less than a magnitude 3. It typically takes an earthquake of magnitude 4. Though earthquakes greater than magnitude 6 are uncommon in Yellowstone, some have occurred. The most famous, and most tragic, earthquake in the Yellowstone area happened 57 years ago today.
The 7. On the evening of August 17, , around visitors slept throughout the Madison River canyon near Hebgen Lake, just west of Yellowstone.
Some bedded down in private cabins and resorts, others at Forest Service campgrounds or makeshift campsites along the roadsides. Just before midnight, an earthquake jolted the travelers from their sleep. Every few thousand years, a hydrothermal explosion will form a crater as Can we drill into Yellowstone to stop it from erupting? In some cases, limited scientific drilling for research can help us understand magmatic and hydrothermal hot water systems; however, drilling to mitigate a volcanic threat is a much different subject with unknown consequences, high costs, and severe environmental impacts.
In addition to the enormous expense and technological difficulties in Do earthquakes large enough to collapse buildings and roads accompany volcanic eruptions? Not usually. Earthquakes associated with eruptions rarely exceed magnitude 5, and these moderate earthquakes are not big enough to destroy buildings and roads.
The largest earthquakes at Mount St. Helens in were magnitude 5, large enough to sway trees and damage buildings, but not destroy them. During the huge eruption of Mount Pinatubo in Can an eruption at one volcano trigger an eruption at another volcano? There are a few historic examples of simultaneous eruptions from volcanoes or volcanic vents located within about 10 kilometers 6 miles of each other, but it's difficult to What is the relationship between volcanism and the geysers and hot springs in Yellowstone?
Heat and volcanic gases from slowly cooling magma rise and warm the dense salty water that occupies fractured rocks above the Yellowstone magma chamber. That brine, in turn, transfers its heat to overlying fresh groundwater, which is recharged by rainfall and snowmelt from the surface.
Water boiling at depth below the surface is hotter than the Filter Total Items: 7. Year Published: Yellowstone Volcano Observatory annual report The Yellowstone Volcano Observatory YVO monitors volcanic and hydrothermal activity associated with the Yellowstone magmatic system, conducts research into magmatic processes occurring beneath Yellowstone Caldera, and issues timely warnings and guidance related to potential future geologic hazards.

Dzurisin, Daniel; Wicks, Charles W. Year Published: Protocols for geologic hazards response by the Yellowstone Volcano Observatory The Yellowstone Plateau hosts an active volcanic system, with subterranean magma molten rock , boiling, pressurized waters, and a variety of active faults with significant earthquake hazards. Year Published: Steam explosions, earthquakes, and volcanic eruptions -- what's in Yellowstone's future?
Once a seismic wave reaches the surface of the Earth, it may be felt. Structures are susceptible to earthquake damage because the ground motion is dominantly horizontal. Without periodic disturbance from relatively small earthquakes, the small fractures and conduits that supply hot water to geysers and hot springs might be sealed by mineral deposition. For example, the Hebgen Lake 7. The largest swarm occurred in , with more than 3, earthquakes recorded during three months on the northwest side of the park.
Hundreds of quakes were recorded during swarms in near Lake Village and between Old Faithful area and West Yellowstone. Earthquakes help us to map and to understand the sub-surface geology around and beneath Yellowstone. The energy from earthquakes travels through hard and molten rock at different rates. An extensive geological monitoring system is in place to aid in that interpretation.
On June 16, at pm Mountain Daylight Time, the largest earthquake of occurred. The magnitude 4. The earthquake was reported felt in the towns of Gardiner and West Yellowstone, Montana.
It was the largest quake since the 4. This earthquake was part of an energetic swarm in the same area. A cluster of more than 2, earthquakes was recorded in the area six miles north of West Yellowstone, Montana, and on the west side of the park. In November , the University of Utah, in collaboration with the University of Texas El Paso and Yellowstone National Park, installed nodal seismometers in and around the Upper Geyser Basin in a continuation of a study that started in The temporary deployment, which lasted several days, was intended to record seismic signals from the various thermal features.
From 1, to 2, earthquakes typically occur each year within Yellowstone National Park and its immediate surroundings. Earthquake damage from the Hebgen Lake event in the Yellowstone Plateau.

Although most are too small to be felt, these quakes reflect the active nature of the Yellowstone region, one of the most seismically active areas in the United States. Each year, several earthquakes of magnitude 3 to 4 are felt by people inside and ouside the park.
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.
