Augustine Volcano (Alaska) during its eruptive phase on January 24, 2006. A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.
Mount Tarumae erupting in 1909. The most recent eruption, in 1982, was a phreatic eruption. [4] Previous major eruptions have occurred in 1667, 1739 (plinian eruption of VEI 5 [5]), and 1909.
Young volcanoes are rarely found within cratons, but are characteristic of subduction zones, rift zones, or in ocean basins. Intraplate volcanoes are clustered along hotspot traces. [2] Within regions of volcanic activity, volcanic fields are clusters of volcanoes that share a common magma source. [3]
The volcano lies 80.87 miles west of Anchorage and NE of Chakachamna Lake. The caldera was formed by a late-Pleistocene or early Holocene sector collapse and associated pyroclastic flows that destroyed an ancestral Spurr volcano. The debris avalanche traveled more than 15.5 miles to the SE, and the resulting deposit contains blocks as large as ...
An example is the massive Level Mountain shield volcano in northern British Columbia, Canada, which covers an area of 1,800 km 2 (690 sq mi) and a volume of 860 km 3 (210 cu mi). [ 1 ] Perhaps the most extensive of all the subaerial basaltic plateaus existed during the Paleogene [ 2 ] and possibly extended over 1,800,000 km 2 (690,000 sq mi) of ...
The Yellowstone Plateau Volcanic Field, also known as the Yellowstone Supervolcano or the Yellowstone Volcano, is a complex volcano, volcanic plateau and volcanic field located mostly in the western U.S. state of Wyoming, but it also stretches into Idaho and Montana. [4] [5] It is a popular site for tourists. [6] Map of Yellowstone Volcano ash beds
