Within the United States, the only active volcanoes are located in Alaska, Hawaii, and the Pacific Northwest. There are volcanoes in other states, but they are not active and pose no significant threat.
A volcano is a breach in the earth’s surface or crust. Most volcanoes are dormant and are no cause for concern; however active volcanoes pose a threat when an eruption occurs. Volcanoes erupt when pressure deep inside the earth builds up and is suddenly released. Debris which includes hot lava (or magma), dangerous gases, and huge rocks can be hurled into the air sometimes traveling for hundreds of miles.
The most dangerous type of volcano is referred to as a Super Volcano. A Super Volcano usually takes the form of a huge caldera. A caldera is where the land surrounding a volcano collapses following a previous eruption. This is different from traditional volcanoes, where an eruption forms a cone shaped mountain. An eruption of a Super Volcano can result in catastrophic damage to an entire continent. They can eject enough ash into the atmosphere to lower the Earth’s temperature for many years. Yellowstone National Park is the site of a super volcano called the Yellowstone Caldera. While this volcano has the potential to devastate a good portion of the United States one day, it has not erupted in 640,000 years and in most scientists estimates it is not showing signs of a large eruption any time soon.
There is no accurate method for predicting when a volcano may erupt. However, scientists consider a volcano to be active if it is currently erupting, or showing signs of a potential eruption. Signs could be in the form of elevated gas emissions or a change of shape in the surrounding landscape (like what was witnessed at the Mount St Helen’s Eruption in Washington).
There are currently 50 active volcanoes in the United States.
Volcanoes usually show signs of an impending eruption, which provides time for people located in the immediate vicinity to take precautions.
