Poland added that the effects would also be felt beyond the United States' borders. When will the next large earthquake occur in Yellowstone? Tracking changes in Yellowstone's restless volcanic system. 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. Yellowstones steaming attractions bring in millions of visitors who enjoy the spectacular sights. What is a supereruption? The take-home message is that the magma chamber is mostly solid. Yellowstone is the largest volcanic system in North America, second-most in the world, and its most active supervolcano hotspot has moved toward the Northeast over time. This comes out to an average of about 725,000 years between eruptions. Yellowstone is a plateau high in the Rocky Mountains, and is snowbound for over six months per year. "Initial findings were that the magma chamber beneath Yellowstone was only 5-15% molten. Ever since the 4.8 earthquake that struck the park on March 30 the largest . The "huge mountain" in this instance is believed to be Yellowstone. The most likely explosive event to occur at Yellowstone is actually a hydrothermal explosion (a rock hurling geyser eruption) or a lava flow. The supervolcano, or caldera, sitting under Yellowstone National Park is nearing a cataclysmic eruption, and the government has been silently evacuating local towns in preparation. Yellowstone's supervolcano last erupted 70,000 years ago. Why the Yellowstone Supervolcano Could Be Huge Smithsonian Channel 4.03M subscribers Subscribe 35K 5.3M views 7 years ago One of the world's largest supervolcanoes erupted 2.1 million years ago.

The largest earthquake of the month in this sequence, a magnitude 2.4 event, occurred on February 14 at 3:03 AM MST. The resulting volcanism has been characterized by the eruption of voluminous rhyolites and subordinate basalts but virtually no lavas of intermediate composition. The chamber is mostly solid, with only about 5-15% melt. Volcanic debris from these eruptions has been discovered as far south as Louisiana and as far west as California. Just because Yellowstone has produced three very large eruptions over the last 2.2 million years doesn't mean that you should expect such an eruption.

Chart and map of ancient eruptions of Yellowstone supervolcano. Though we've been looking at Yellowstone for years, no one has yet identified "long-period (LP) events" commonly attributed to magma movement. Yellowstone hasn't erupted for 70,000 years, so it's going to take some impressive earthquakes and ground uplift to get things started. Winds would also carry ash to Europe and the rest of the world, where it could trigger extreme weather changes. Almost all earthquakes at Yellowstone are brittle-failure events caused when rocks break due to crustal stresses. "They erupt when there is enough eruptible magma beneath the surface, and pressure to cause that magma to ascend. Keep in mind that this evacuation order would go far beyond a 50-mile radius due to the amount of ash and debris that follows lava or magma substances. In the next few hundred years, hazards will most probably be limited to ongoing geys, 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. 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. Related: The 11 biggest volcanic eruptions in history Research published in the journal Science (opens in new tab) in December 2022 found that the Yellowstone caldera holds more liquid molten rock than previously estimated. They claim that because the last eruption of the supervolcano was 70,000 years ago (opens in new tab), it's bound to blow soon. Yellowstone is a supervolcano, meaning that, when it erupts, it releases significantly more energy than other volcanoes.

Those parts of the surrounding states of Montana, Idaho, and Wyoming that are closest to Yellowstone would be affected by pyroclastic flows, while other places in the United States would be impacted byfalling ash (the amount of ash would decrease with distance from the eruption site). An official website of the United States government. "Neither condition is in place at Yellowstone right now," he added. According to the U.S. Department of the Interior (opens in new tab), "the surrounding states of Montana, Idaho, and Wyoming that are closest to Yellowstone would be affected by pyroclastic flows, while other places in the United States would be impacted by falling ash." "Sometimes it erupts quietly with lava flow, but once or twice every million years, it erupts very violently, forming large calderas," which are very large craters measuring tens of kilometers in diameter. Most of the national park and vicinity are sparsely populated, but significant numbers of people as well as park resources could nevertheless be at risk from these hazards. A new study has found that before a catastrophic eruption takes place, the ground will likely begin to swell up.
