Historically, four types of volcanic events have taken place in Yellowstone (you may click on each one to learn more):
- 1. Caldera Forming Eruptions — 2.1 and 1.3 million years ago
- 2. Lava Flows — about 30 between 640,000 and 70,000 years ago
- 3. Earthquakes — 1000 to 3000 yearly; last notable quake was in 1959
- 4. Hydrothermal (Steam) Explosions — small explosions in the 20th century; a
How likely is it that Yellowstone will erupt?
How likely is it that Yellowstone will erupt? ANSWER: Although it is possible, scientists are not convinced that there will ever be another catastrophic eruption at Yellowstone. Given Yellowstone’s past history, the yearly probability of another caldera-forming eruption can be approximated as 1 in 730,000 or 0.00014%.
Can We Survive a Yellowstone eruption?
Not if you live anywhere in North America. An eruption of a supervolcano in Yellowstone National Park would leave no place to escape to, as it would deposit ash as far afield as Los Angeles, New York and Miami, a study has revealed.
How big was the most recent eruption at Yellowstone?
This eruption deposited 1,000 cubic kilometers of rock and spread ashy material across the western United States, southern Canada, and northern Mexico.
How many eruptions has Yellowstone experienced?
How many times has Yellowstone erupted? In terms of large explosions, Yellowstone has experienced three at 2.08, 1.3, and 0.631 million years ago. This comes out to an average of about 725,000 years between eruptions.
What would a Yellowstone eruption be like?
The enormous amount of volcanic material in the atmosphere would subsequently rain down toxic ash; across the entire US, but principally in the Northwest. The ash would also kill plants, animals, crush buildings with its weight, block freeways, and ruin the country's farmland for a generation.
Is Yellowstone explosive or non explosive?
The most recent eruption formed the Yellowstone caldera. Since then, the park has seen roughly 80 mostly non-explosive eruptions.
What would happen if Yellowstone erupted simulation?
The simulation uses a lot of assumed numbers, and according to Mike Poland, the volcanologist in charge of Yellowstone, if Yellowstone erupted, we would see much more earth lifted up and larger earthquakes. Additionally, the hundreds of earthquakes that are recorded across the part would also turn into thousands.
How likely is it that Yellowstone will erupt?
ANSWER: Although it is possible, scientists are not convinced that there will ever be another catastrophic eruption at Yellowstone. Given Yellowstone's past history, the yearly probability of another caldera-forming eruption can be approximated as 1 in 730,000 or 0.00014%.
Will the Yellowstone volcano erupt?
Unlikely to Erupt In fact, officials at the Yellowstone Volcano Observatory say the most likely activities that might take place in the future are hydrothermal explosions (eruptions of steam and hot water, rather than molten rock) or lava flows.
When did Yellowstone last erupt?
70,000 years agoThe most recent volcanic eruption at Yellowstone, a lava flow on the Pitchstone Plateau, occurred 70,000 years ago.
What would happen if Old Faithful blew?
If the supervolcano underneath Yellowstone National Park ever had another massive eruption, it could spew ash for thousands of miles across the United States, damaging buildings, smothering crops, and shutting down power plants. It'd be a huge disaster.
When was the last time Yellowstone erupted?
The most recent volcanic activity at Yellowstone consisted of rhyolitic lava flows that erupted approximately 70,000 years ago.
How many years has Yellowstone erupt?
In terms of large explosions, Yellowstone has experienced three at 2.08, 1.3, and 0.631 million years ago. This comes out to an average of about 725,000 years between eruptions. That being the case, there is still about 100,000 years to go, but this is based on the average of just two numbers, which is meaningless.
How much volcanic activity has there been at Yellowstone since the most recent giant eruption?
Since the most recent giant ( caldera-forming ) eruption 631,000 years ago, approximately 80 relatively nonexplosive eruptions have occurred. Of these eruptions, at least 27 were rhyolite lava flows in the caldera, 13 were rhyolite lava flows outside the caldera, and 40 were basalt vents outside the caldera. The most recent volcanic eruption at...
When will the next large earthquake occur in Yellowstone?
Earthquakes cannot be predicted yet, but modern surveillance conducted with seismographs (instruments that measure earthquake locations and magnitudes) and Global Positioning System (GPS) instruments that measure slow ground movements help scientists understand the state of stress in the Earth's crust. Those stresses could trigger earthquakes as...
Why are there so many earthquakes at Yellowstone?
Almost all earthquakes at Yellowstone are brittle-failure events caused when rocks break due to crustal stresses. Though we've been looking at Yellowstone for years, no one has yet identified "long-period (LP) events" commonly attributed to magma movement. If LP events are observed, that will NOT mean Yellowstone is getting ready to erupt. LP...
When was the last time Yellowstone erupted?
The most recent volcanic activity at Yellowstone consisted of rhyolitic lava flows that erupted approximately 70,000 years ago. The largest of these flows formed the Pitchstone Plateau in southwestern Yellowstone National Park.

How big is the magma chamber under Yellowstone?
The shallower one is composed of rhyolite (a high-silica rock type) and stretches from 5 km to about 17 km (3 to 10 mi) beneath the surface and is about 90 km (55 mi) long and about 40 km (25 mi) wide. The chamber is mostly solid, with only about 5-15% melt. The deeper reservoir is composed of basalt...
How much ash does Yellowstone Supereruption produce?
Yellowstone is one of a few dozen volcanoes on earth capable of "supereruptions" that expel more than 1,000 cubic km of ash and debris. The plumes from such eruptions can rise 30 to 50 km into the atmosphere, three to five times as high as most jets fly.
How many types of volcanic events have occurred in Yellowstone?
Historically, four types of volcanic events have taken place in Yellowstone (you may click on each one to learn more):
Is there a future eruption of yellowstone?
Although no eruptions of lava or volcanic a sh have occurred for many thousands of years, future eruptions are likely.
Is Yellowstone National Park dangerous?
According to the USGS, none of these events are common in Yellowstone. Although visitors to Yellowstone National Park in the immediate future may never experience such events, some hazardous events are certain to occur in the future.
Is there an earthquake in Yellowstone National Park?
It is true that earthquakes are a daily occurrence in the Yellowstone region, yet most are under 3.0 magnitude, and very few are actually felt. However, there is little to worry about in terms of actual danger at this time. According to the United State Geological Survey, “Yellowstone has produced several giant volcanic eruptions in ...
What falls are on the Yellowstone rim?
Gibbon Falls, Lewis Falls, Lake Butte, and Flat Mountain Arm of Yellowstone Lake are part of the rim. The YVO is watching closely for that activity.
Why are Yellowstone's geysers and hot springs so important?
Lowenstern explains that Yellowstone’s geysers and hot springs are a direct consequence of the volcanic system. These features exist because of the high heat discharge from the molten rock that fuels the volcanic eruptions. Heat is conducted from the molten rock—found four to five miles beneath the surface of the park—upward to ...
Who is the scientist in charge of the Yellowstone Volcano?
The Yellowstone “supervolcano” is a topic surrounded by much curiosity and—sometimes—speculation. For the real facts, we went straight to an expert, Jake Lowenstern of the U.S. Geological Survey (USGS). Lowenstern is Scientist-in-Charge of the Yellowstone Volcano Observatory (YVO), which monitors the Yellowstone caldera.
How long ago was the last eruption of Yellowstone?
Considering that the last large volcanic eruption at Yellowstone took place over 2 million years ago, we assume it safe to bet you wouldn’t recall the ramifications from that event. Let us fill you in. Believe it or not, researches found ashes from the explosion throughout tens of thousands of kilometers, tracing as far as Canada and even ...
Is Yellowstone a super eruption?
The potential for mass disruption and catastrophic effects has had people honing in on Yellowstone for years. The magnitude of a super eruption threat is high, while the possibility is very low. The super eruptions are massive compared to even the largest explosions that we have ever seen, and have the ability to bury entire states.
