Seismologists have known for many decades about the presence of a potential supervolcano in Yellowstone National Park. The Yellowstone Caldera volcano hasn’t erupted in 70,000 years, but concerns it could occur again soon are running high after weeks of small earthquakes hit the region.
One phenomenon scientists keep an eye on is the level of earthquake activity that might signal changes occurring in the magma moving underneath the earth’s crust.
Volcanoes are a natural presence around the globe, with many famous eruptions occurring in the past that dramatically affected nearby surroundings.
On another level, the Hawaiian Islands have volcanoes that erupt from time to time, producing lava that pours down their sides and often goes into the sea. Local residents know it’s just something they have to live with, so it’s not a major concern.
For residents in the area near the Caldera volcano, a sudden increase in earthquake activity can set their nerves on edge. On the next page, learn about a recent spike in earthquake activity and what a Caldera major eruption could mean for Yellowstone, the United States and the world in general.
