There have most likely been millions of active volcanoes throughout the earth’s history. Over the last 10,000 years, around 1500 volcanoes on land have been known to have been active, whereas the number of undersea volcanoes is unknown. There are approximately 20 volcanoes erupting at any given time. A volcano that has erupted at least once in the last 10,000 years is known as an active volcano. It’s possible that an active volcano is erupting or is dormant.
