World map of active volcanoes and plate boundaries Kīlauea's lava entering the sea Lava flows at Holuhraun, Iceland, September 2014. An active volcano is a volcano that has erupted during the Holocene (the current geologic epoch that began approximately 11,700 years ago), is currently erupting, or has the potential to erupt in the future.

On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example, a mid-ocean ridge , such as the Mid-Atlantic Ridge , has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has ...

Mount Erebus is the southernmost active volcano on Earth, and one of only two in Antarctica. Its summit is 12448 feet. The volcano was discovered and named by Sir. James Clark Ross in January of 1841.
Elsewhere, the active volcano of Kilauea in Hawaii had been erupting almost constantly from its eastern rift zone since 1983. Then in April 2018, its 35-year-long eruption ended.
This beautiful and active volcano on the Big Island of Hawaii has been in eruption since millions of years ago, and began spewing lava flows on Nov. 27, 2022. for the first time since 1984.
As of January 2024, Halemaʻumaʻu is not erupting and the lava lake is no longer active. Nyiragongo's lava lake has usually been the largest and most voluminous in recent history, reaching 700 meters wide in 1982, [ 15 ] although Masaya is believed to have hosted an even larger lava lake at the time of the Spanish conquest , being 1,000 meters ...
A volcanic belt is a large volcanically active region. Other terms are used for smaller areas of activity, such as volcanic fields or volcanic systems. Volcanic belts are found above zones of unusually high temperature (700 to 1,400 °C (1,292 to 2,552 °F)) where magma is created by partial melting of solid material in the Earth's crust and ...
