Once a major tourist attraction, Naple’s Phlegraean Fields are now a major scare. Recent news that a new supervolcano lies hidden somewhere near Pompeii have scared millions in Italy, but the threat affects Earth at a greater scale. An eruption poses a danger of global proportions, comparable to major meteorite impacts. There are 3 million people living in Naples and the surrounding territory – and they stand no chance if the volcano erupts.
In 79 A.D. Mount Vesuvius buried the ancient Roman city of Pompeii under a thick layer of volcanic ash. As a more recent example, when Mount St. Helens erupted in 1980, it ejected 0.3 cubic miles of debris and generated 1,600 times the explosive force of the Hiroshima bomb. These disaster pale in comparison with what can happen next.
The newly discovered Pompeii supervolcano is not the only one in the world. Other supervolcanoes are active in Yellowstone Caldera, Valles Caldera and Long Valley Calder in the USA; near Lake Toba in Indonesia; in New Zeeland and in Japan.
