The Caldera inside Yellowstone National Park is called a supervolcano because of its ability to cause huge destruction in the event of an eruption. If this happens, humanity will face an unprecedented catastrophe, said scientist Bryan Walsh.

The main signs of the volcano’s awakening will be increasing earthquakes in the region, which will indicate the rise of magma, he explained. “Then magma will break through the earth in a Titanic eruption, throwing toxic gases into the air. This will continue for several days, and Yellowstone will sink into the lava within a 40-mile (64 km) radius,” Walsh added.

At the same time, the destruction around the volcano will only be the beginning. Under a layer of ash up to one and a half meters thick will be several states. All crops and pastures will be destroyed, and power lines will be destroyed. According to Walsh, the consequences may be more global if the eruption occurs in the summer. Then toxic substances in the atmosphere will block sunlight and lower global temperatures for years to come.

“The amount of precipitation will decrease sharply. This may be enough to trigger the extinction of tropical forests. Agriculture will be destroyed,” he added.

However, the US Geological Survey (USGS) says there is nothing to fear. Now, the probability of an eruption is estimated at 1 in 730000. Also, the activity of the volcano is in decline.

Earlier it was reported that a group of scientists found a way to find out exactly where the next major lava release in Yellowstone may occur. In their work, they investigated the paths that magma can take and tried to establish the points to break out to the surface.
