When supereruptions do occur more than once in a volcanic system, they are not evenly spaced in time. Although another catastrophic eruption at Yellowstone is possible, scientists are not convinced that one will ever happen. If Yellowstone does erupt again, it need not be a large eruption. The most recent volcanic eruption at Yellowstone was a lava flow that occurred 70, years ago.

Learn more: Yellowstone Volcano Observatory. 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.

This report summarizes the activities and When erupting, all volcanoes pose a degree of risk to people and infrastructure, however, the risks are not equivalent from one volcano to another because of differences in eruptive style and geographic location. Assessing the relative threats posed by U. Rimmed by a crescent of older mountainous terrain, Yellowstone National Park has at its core the Quaternary Yellowstone Plateau, an undulating landscape At least volcanoes in 12 States and 2 territories have erupted in the past 12, years and have the potential to erupt again.

Consequences of eruptions from U. Many aspects of our daily life are vulnerable to volcano hazards, 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.

Within the next few decades, light-to-moderate earthquakes and steam explosions are certain to occur.

Volcanic eruptions are less likely, but are ultimately Although no eruptions of lava or volcanic ash have occurred for many thousands of years, future eruptions are likely. In the next few hundred years, Skip to main content. Search Search. Natural Hazards. Apply Filter. 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 What is a supervolcano?

What is a supereruption? The term "supervolcano" implies a volcanic center that has had an eruption of magnitude 8 on the Volcano Explosivity Index VEI , meaning that at one point in time it erupted more than 1, cubic kilometers cubic miles of material.

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.

When was the last time Yellowstone erupted? Many aspects of our daily life are vulnerable to volcano hazards, Although no eruptions of lava or volcanic ash have occurred for many thousands of years, future eruptions are likely.

In the next few hundred years, This region of Yellowstone National Park has been the active focus of one of the Earth's largest magmatic systems for more than 2 million years.

The resulting volcanism has been characterized by the eruption of voluminous rhyolites and subordinate basalts but virtually no lavas of intermediate composition. The magmatic system at depth remains Helens was waking up.

Within a week, several eruptions blasted clouds of ash into the atmosphere, and soon after, a new lava dome emerged in the crater. The cataclysmic eruption of Mt. Pinatubo in the Philippines on June 15, was the second largest eruption of the 20th century. Ash buries cars and buildings after the eruption of Rabaul, Papua New Guinea.

Credit: USGS. Kenneth Pierce studied the geology and geomorphology of the greater Yellowstone area for nearly his entire career with the U. Geological Survey. From to present, Dr. Pierce has mapped glacial deposits, pioneered Quaternary dating techniques, conducted research on the Yellowstone Hot Spot, studied the geothermal areas, explored the geology of archaeological sites.

More than 80, and possibly several hundred, people were killed by the eruption soon after the footprints were made. This is just a portion of the eruption cloud, which extended for more than miles to the northwest at the time this image was collected. In this image, the distance from the erupting vent to the upper left corner of the image. A caldera is a large, usually circular volcanic depression formed when magma is withdrawn or erupted from a shallow underground magma reservoir.

It is often difficult to visualize how calderas form. This simple experiment using flour, a balloon, tubing, and a bicycle pump, provides a helpful visualization for caldera formation. Professor Michael Ort Northern Arizona University and graduate student Joel Unema examine deposits from the eruption of Okmok volcano in Alaska as part of their research to reconstruct the complex history of the eruption.

The term "supervolcano" implies a volcanic center that has had an eruption of magnitude 8 on the Volcano Explosivity Index VEI , meaning that at one point in time it erupted more than 1, cubic kilometers cubic miles of material. When was the last time Yellowstone erupted? The most recent volcanic activity at Yellowstone consisted of rhyolitic lava flows that erupted approximately 70, years ago.

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. How far would ash travel if Yellowstone had a large explosive eruption?

Knowledge about past eruptions of Yellowstone combined with mathematical models of volcanic ash dispersion help scientists determine where and how much ashfall will occur in possible future eruptions. During the three caldera-forming eruptions that occurred between 2. Connections Featured in Screenwipe: Episode 1. User reviews 42 Review. Top review. It is very well explained, anyone could understand it, and even if they do use holographic projectors and things that haven't been invented yet, it does help people understand more easily.

This documentary is aimed at anyone. It is based on scientific evidence so even if it hasn't happened yet, it is based on past happenings in the Yellowstone area and very sound predictions on volcanic activity based on years of research so therefore it isn't science fiction as the guy before said.

For anyone who is interested in the earth and things like volcanoes this is a very worthwhile documentary to watch. Details Edit. Release date April 10, United States. BBC United Kingdom.
