Hydrothermal explosions are very small; they occur in Yellowstone National Park every few years and form a crater a few meters across. Every few thousand years, a hydrothermal explosion will form a crater as How far in advance could scientists forecast an eruption of the Yellowstone volcano? The science of forecasting a volcanic eruption has significantly advanced over the past 25 years. Most scientists think that the buildup preceding a catastrophic eruption would be detectable for weeks and perhaps months to years.
Precursors to volcanic eruptions include strong earthquake swarms and rapid ground deformation and typically take place Can we use the heat from Yellowstone for energy? Geothermal energy heat energy from the Earth's interior , is used to generate electricity in a variety of places throughout the world.
Although Yellowstone National Park and its surroundings are a significant geothermal resource, the Park itself is off limits to development. Geothermal developments often cause a decrease in the flow of nearby hot 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 How can we tell when a volcano will erupt? Most volcanoes provide warnings before an eruption. Magmatic eruptions involve the rise of magma toward the surface, which normally generates detectable earthquakes.
It can also deform the ground surface and cause anomalous heat flow or changes in the temperature and chemistry of the groundwater and spring waters. Steam-blast eruptions, however, What is the difference between "magma" and "lava"? Scientists use the term magma for molten rock that is underground and lava for molten rock that breaks through the Earth's surface.
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 Filter Total Items: 4.
Pat; Lowenstern, Jacob B. View Citation. Morgan, L. Not likely. The most likely activity would be lava flows, such as those that occurred after the last major eruption. A lava flow would ooze slowly over months and years, allowing plenty of time for park managers to evaluate the situation and protect people.
No scientific evidence indicates such a lava flow will occur soon. YVO scientists monitor Yellowstone volcano with a real time and near real-time monitoring network of 26 seismic stations, 16 GPS receivers, and 11 stream gauging stations. Scientists also collect information is on temperature, chemistry, and gas concentrations at selected hydrothermal features and chloride concentrations in major rivers.
A monthly activity summary, real-time monitoring of seismicity and water flow, and near real-time monitoring of ground deformation, can be found at the Yellowstone Volcanic Observatory website. Scientists from the Yellowstone Volcano Observatory watch an array of monitors in place throughout the region. These monitors would detect sudden or strong earthquake activity, ground shifts, and volcanic gasses that would indicate increasing activity.
No such evidence exists at this time. In addition, Yellowstone Volcano Observatory scientists collaborate with scientists from all over the world to study the hazards of the Yellowstone volcano.

Yellowstone's hydrothermal systems are the visible expression of the immense Yellowstone volcano.
Yellowstone preserves earth's most extraordinary collection of hot springs, geysers, mudpots, fumaroles, and travertine terraces. A mountain range near Heart Lake located entirely within Yellowstone and named for their red volcanic rock. A volcano, geysers and other thermal features, earthquakes, and glaciers shape Yellowstone's landscape.

The steep, columnar basalt cliffs on the opposite side of the river from the Tower Fall overlook are remnants of an ancient lava flow, providing a window into the past volcanic forces that shaped much of the Yellowstone landscape. Yellowstone's Restless Giant The Yellowstone supervolcano is one of our planet's restless giants.
Duration: 5 minutes, 55 seconds. The location of Yellowstone's three calderas and two resurgent domes. Volume comparison of global volcanic eruptions. Siegel, Recent Activity Remarkable ground deformation has been documented along the central axis of the caldera between Old Faithful and White Lake in Pelican Valley in historic time. Molten rock, or magma, rises in convection cells like water boiling in a pot.
A hot spot may arise from a heated plume originating from the mantle-core boundary left side of illustration , or one originating from higher up in the mantle right side of illustration. The magma reservoirs of the Yellowstone hot spot originate at a much shallower depth than the mantle plume. Frequently Asked Questions Is Yellowstone a volcano? Within the past two million years, some volcanic eruptions have occurred in the Yellowstone area—three of them super eruptions.
What is the caldera shown on the park map? The Yellowstone caldera was created by a massive volcanic eruption approximately , years ago. Later lava flows filled in much of the caldera, now it is 30 x 45 miles. When did the Yellowstone volcano last erupt?
The mantle plume that currently exists beneath Yellowstone generated hot basalt magmas at depth, which ascended into the lower crust where they melted continental crust to produce the rhyolitic magmas. These rhyolite melts then ponded beneath the Yellowstone region, in a shallow magma chamber that generating doming and the development of ring fractures on the Yellowstone surface.
Explosive volcanism above this elevated and fractured dome began about , years ago, and collapse of the structure soon followed. Yellowstone Caldera -- The ascent of hotspot-generated basaltic magmas results in melting of the continental crust to produce rhyolitic magmas.
