Small eruptions (such as in 2009 and 2014/15) occur mainly at the edge of the caldera, but very big ones come from the caldera itself. These big eruptions are so large the top of the erupting ...

New research into volcanic eruptions could help predict their hazards, including tsunamis and surfing hot rock avalanches. Explosive research Volcanic eruptions large enough to create a caldera, or ...

The Yellowstone Caldera is a 30x45 mile (50x70 km) depression which was formed by a cataclysmic eruption some 640,000 years ago.

The eruption is flowing into a remote area of Hawaii Volcanoes National Park. Flows have been confined to the Halemaʻumaʻu crater and the southwest side of Kaluapele, Kīlauea's summit caldera.
