If Yellowstone's supervolcano were to erupt, it could cause devastating local destruction from pyroclastic flows and ash fall, and lead to global climate cooling with temperatures dropping up to 12 degrees for several years, potentially causing widespread famine. However, scientists believe such an eruption is unlikely in the near future, as the volcano is dormant and the magma chambers are cooling.
Thousands of people have evacuated regions surrounding the Mayon Volcano in the Philippines as the mountain continues to spew lava and show increasing signs of unrest. The volcano's activity has led officials to raise the alert level to Alert Level 3, and numerous earthquakes have been reported. Scientists have noted a sharp increase in rockfall events and pyroclastic flows from the volcano's lava dome. A nearly 4-mile radius around the volcano has been declared a Permanent Danger Zone, forcing thousands of people to flee their homes.
The Fuego Volcano, located less than 30 miles from Guatemala City, has erupted, sending ash, gas, and rocks down the mountainside. Several small villages have been evacuated as a preventative measure due to the threat of pyroclastic flows. The volcano has been erupting since 2002, but this recent event is the most significant in several years. Guatemala is home to more than 30 volcanoes, with three considered active - Pacaya, Fuego, and Santa Maria.
