A supervolcano is a volcano that has had an eruption with a volcanic explosivity index (VEI) of 8, [1] the largest recorded value on the index. This means the volume of deposits for such an eruption is greater than 1,000 cubic kilometers (240 cubic miles).
The scale of La Garita volcanism was the second greatest of the Cenozoic Era.The resulting Fish Canyon Tuff has a volume of approximately 1,200 cubic miles (5,000 km 3), giving it a volcanic explosivity index rating of 8. [6]
Forecasting supervolcano eruptions is an inexact science, and the researchers end their paper by calling for continued monitoring of the area, not an evacuation. Scientists Could Soon Predict ...
Two long-dormant “supervolcanoes” on two separate continents appear to be stirring to life. Well, maybe. In recent months, more than a thousand minor earthquakes have rattled the area around ...
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.
The central volcano of Bárðarbunga, the Veidivötn and Trollagigar fissures form one volcanic system, which extend about 100 km SW to near Torfajökull volcano and 50 km NE to near Askja volcano, respectively. The subglacial Loki-Fögrufjöll volcanic system located SW of Bárðarbunga volcano is also part of the Bárðarbunga volcanic system ...
The most recent two high-precision argon–argon datings dated the eruption to 73,880 ± 320 [6] and 73,700 ± 300 years ago. [7] Five distinct magma bodies were activated within a few centuries before the eruption. [8] [9] The eruption commenced with small and limited air-fall and was directly followed by the main phase of ignimbrite flows. [10]
Articles about people, places, or other entities notable for their association with a volcano or volcanoes, including volcano gods and victims. For example, Pompeii, Harry Randall Truman, and Pele. Articles about sheet intrusions (e.g. dikes, dike swarms, sills) where they are connected with large igneous provinces or other volcanic activity.
