Largest Underwater Eruption Ever Recorded Gives Birth to Massive New Volcano
SciAlert ^ | 30 SEPTEMBER 2021 | MICHELLE STARR

Posted on 09/30/2021 7:21:14 AM PDT by BenLurkin

A huge seismic event that started in May of 2018 and was felt across the entire globe has officially given birth to a new underwater volcano.

Off the eastern coast of the island of Mayotte, a gigantic new feature rises 820 meters (2,690 feet) from the seafloor, a prominence that hadn't been there prior to an earthquake that rocked the island in May 2018.

French governmental institutions sent a research team to check it out; there, sure enough, was an undersea mountain that hadn't been there before.

Led by geophysicist Nathalie Feuillet of the University of Paris in France, the scientists have now described their findings in a new paper.

The team began monitoring the region in February of 2019. They used a multibeam sonar to map an 8,600-square-kilometer area of seafloor. They also placed a network of seismometers on the seafloor, up to 3.5 kilometers deep, and combined this with seismic data from Mayotte.

Between 25 February and 6 May 2019, this network detected 17,000 seismic events, from a depth of around 20 to 50 kilometers below the ocean floor – a highly unusual finding, since most earthquakes are much shallower. An additional 84 events were also highly unusual, detected at very low frequencies.

Armed with this data, the researchers were able to reconstruct how the formation of the new volcano may have occurred. It started, according to their findings, with a magma reservoir deep in the asthenosphere, the molten mantle layer located directly below Earth's lithosphere.

Interesting. The volcano is growing rapidly. Keep it up and it may break the surface of the ocean.

Have the Biden Democrats blamed “climate change” for this yet?

They should say NW of Madagascar, that gives a better general location.
