What would it take for the world’s largest volcano to erupt?
Sharjah24 – Reuters: New data has revealed more about what could trigger eruptions on the world’s largest volcano.
In a study published in Nature Scientific Reports, researchers at the Rosenstiel School of Marine and Atmospheric Science at the University of Miami modeled movements inside the Mauna Loa volcano in Hawaii, which according to the website of the US Geological Survey, has a summit of 17 kilometers, or 56,000 feet, above its submarine base.
The researchers found that although there was recent movement along a fault under the eastern flank, relatively little movement was detected under the western flank. They concluded that an earthquake under the western flank is due.
Along with this, the researchers found that between 2014 and 2020, 0.11 cubic kilometers of new magma made its way into a dike-like body of magma beneath the south of the volcano’s summit.
Given this influx of magma, an earthquake of magnitude 6 or greater could cause an eruption, according to lead study author Bhuvan Varugu. The last time Mauna Loa erupted in 1984, lava was found within 10 kilometers, or 6 miles, of the outskirts of the city of Hilo, according to the Encyclopedia Britannica, although it took weeks. .
