A geologist has said that if the Yellowstone supervolcano erupts, it would destroy most of the United States, all but wiping the country off of the map. Dr. Jerzy Zaba is importantly not predicting that the volcano is going to erupt soon, but simply stating that it does have the power to destroy humanity and life as we know it.
According to Tech WP, Dr. Zaba says that Yellowstone, if it erupted in a similar manner as it did 640,000 years ago, it would destroy much of the United States. Dr. Zaba, who is a geologist at the University of Silesia in Katowice, Poland, said the mass explosion is completely unavoidable although it’s impossible to say when that explosion will occur. In addition to the annihilation of the United States, the geologist also says about 5 billion other people will starve to death in the volcanoes aftermath: a volcanic winter.
It is forecasted that if there was an explosion similar to the one from 640,000. for years, it would destroy most of the United States. Discarded materials would cover everything with a meter layer within a radius of 500 km. And due to the emission of a huge amount of dust, gases or sulfur oxide to the atmosphere, there would be a temporary cooling of the climate. Sulfur oxide would create a thin veil of sulfuric acid around the planet reflecting sunlight. [This] would persist for many years. It is estimated that due to climate change about five billion people would starve to death. The scenario of such an explosion can be seen in the documentary film “Superwulkan – disaster scenario”. This is, of course, a catastrophic film, but a lot of scientific truth in it. –Dr. Jerzy Zaba, via Tech WP
An eruption at Yellowstone would cause the Earth’s temperature to plummet as the sulfuric acid would reflect the sunlight, making growing food difficult across the globe.
As more talk is made by geologists that suggest that the supervolcanoes are “waking up” around the world, the fears will simultaneously spike. That doesn’t mean an eruption will happen anytime soon, only that Earth will experience another supervolcano eruption in the future.
Recently, there was even talk that the Laacher See volcano 650 kilometers from the Polish border has “come to life“. When that volcano last erupted nearly 13 thousand years ago, the population living in its vicinity died out. Europe also then suffered from several colder years of “volcanic winter”.
Experts still say there is no reason to fear a supervolcano eruption just yet, but understanding the devastation that we will all face sooner or later is important in the advancement of science and human survival.
