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.

Scientists monitoring an active volcano will often measure the tilt of the slope and track changes in the rate of swelling. An increased rate of swelling, especially if accompanied by an increase in sulfur dioxide emissions and harmonic tremors is a high probability sign of an impending event.
Volcanology advances have required more than just structured observation, and the science relies upon the understanding and integration of knowledge in many fields including geology, tectonics, physics, chemistry and mathematics, with many advances only being able to occur after the advance had occurred in another field of science.
Volcanoes vary greatly in their level of activity, with individual volcanic systems having an eruption recurrence ranging from several times a year to once in tens of thousands of years. [76] Volcanoes are informally described as erupting, active, dormant, or extinct, but the definitions of these terms are not entirely uniform among ...
In the continental U.S., the most recent cataclysmic eruption of a volcano was Mount St. Helens on May 18, 1980. “Vancouver, Vancouver, this is it!” radioed U.S. Geological Survey scientist ...
Volcanism, vulcanism, volcanicity, or volcanic activity is the phenomenon where solids, liquids, gases, and their mixtures erupt to the surface of a solid-surface astronomical body such as a planet or a moon. [1]
The findings mean that the future of volcanic activity at Yellowstone is in the northeastern part of the park, and there’s no chance it’s going to blow anytime soon.
The video shows August footage from Mount Dukono, an active volcano in Indonesia, not Yellowstone National Park. No evidence supports the post’s claim of a Yellowstone volcanic eruption in ...
