Usa Panic: Yellowstone Volcano Erupts with Deadly Force, Eruption Will Bury US State in Volcanic Ash

Описание к видео Usa Panic: Yellowstone Volcano Erupts with Deadly Force, Eruption Will Bury US State in Volcanic Ash

The Yellowstone Caldera, commonly known as the Yellowstone Supervolcano, has been the subject of apocalyptic speculation over its eruption date. Even before the 2012 sci-fi disaster film terrified audiences with its CGI visuals, many believed that an eruption of the Yellowstone Supervolcano was imminent - with the Caldera erupting roughly every 700,000 years. The impacts of such an event have been well documented.

In 2014, an academic paper suggested that an eruption would bury the surrounding US states in volcanic ash and have a devastating impact on the global climate. But it's important to remember that the 700,000-year interval is not a hard and fast rule. In fact, it's entirely possible that Yellowstone will never erupt again and of course, the United States Geological Survey continues to monitor the sleeping giant. But what is the current status of the Yellowstone Supervolcano? Here's everything you need to know.

According to the USGS, the current status and alert level for the Yellowstone Supervolcano is currently ‘normal.’ The website states that a ‘normal’ alert level means that “the volcano is in a normal background, non-eruptive state or, after changing from a higher level, volcanic activity has ceased and the volcano has returned to a non-eruptive background state.”

In October alone, the USGS recorded 42 earthquakes in the Yellowstone National Park area, but this is still considered ‘normal activity’ by the US government agency. In fact, Yellowstone typically experiences over a thousand earthquakes per year. One indicator that scientists use to determine whether a volcano is about to erupt is the rise of magma to the surface.

However, as the USGS study found, Yellowstone’s magma chamber is only 5%-15% liquid, meaning there may not be enough magma beneath the caldera to cause an eruption. Magma is made up of rocks and crystals of varying viscosity. The more liquid magma stored in a volcano, the more likely it is to erupt.

In 2022, researchers found that Yellowstone’s shallower underground chamber — located three to 10 miles below the surface — likely holds 16% to 20% molten magma. That’s more than the 5% to 15% that scientists initially believed was in the chamber, but it still doesn’t mean the volcano is imminent. For a volcano to erupt, scientists believe it needs to have about 35% to 50% molten magma.
