A major earthquake has triggered an explosive eruption of a volcano with no historical eruptions on record. This could easily progress into a major flank eruption, with the theoretical potential to create a vast lava field along a lengthy magma dike. Today’s video discusses the new eruption of the Krasheninnikov volcano, which much like Mount Fuji in 1707, was triggered to erupt by a megathrust earthquake.Thumbnail Photo Credit: Schaefer, J. R.

Note: While this video’s thumbnail image shows the more explosive 2008 eruption of the Okmok volcano in Alaska, it looks vaguely similar to the ongoing eruption plume.NASA EOSDIS Worldview satellite imagery Copyright © 2012-2025 United States Governmentas represented by the Administrator of theNational Aeronautics and Space Administration.All Rights Reserved.Associated license for NASA EOSDIS Worldview: https://github.com/nasa-gibs/worldvie…We acknowledge the use of imagery provided by services from NASA’s Global Imagery Browse Services (GIBS), part of NASA’s Earth Observing System Data and Information System (EOSDIS).We acknowledge the use of imagery from the NASA Worldview application (https://worldview.earthdata.nasa.gov/), part of the NASA Earth Observing System Data and Information System (EOSDIS).
