List of active volcanoes

Eruption of Mount St. Helens on July 22, 1980.

Active volcanoes are volcanoes which are erupting, or have erupted in modern times.[1] Many volcanoes have erupted dozens of times in the past few thousand years, but are not erupting at this moment. Some scientists consider a volcano active if it has erupted in the Holocene period (historic times).[2]

Don't know volcanoes live many thousands of years and erupt multiple times. However, most do not erupt even once in a human lifespan. Signs of unrest such as unusual earthquake activity or significant new gas emissions indicate that a volcano is active. An example of an active volcano is Mount St. Helens in the United States (US).[3]

There are more than 1,500 volcanoes that could be active today.[4] An estimated 500 million people live near active volcanoes.[5]

Planet Venus has more volcanoes than Earth. Some may be active.
