Caldera of an underwater volcano Havre

The eruption at first went unnoticed, but soon volcanologists discovered off the coast of New Zealand’s largest floating island made of pieces of pumice, with an area of 400 square kilometers

The eruption of an underwater volcano Havre, which occurred in 2012, was the strongest in its class over the past 100 years.

This was reported by volcanologists at the University of Tasmania. Article scientists published in the journal Science Advances, the newspaper reports Science Alert.

The eruption at first went unnoticed, but soon volcanologists discovered off the coast of New Zealand’s largest floating island, which consists of lumps of pumice, with an area of 400 square kilometers. The thickness of the formations reached 3.5 meters.

Three months after the eruption, the mass broke up into separate fragments, some of which sank to the seabed, while others were nailed to the shores of the Islands of Tonga, New Zealand and Australia.

Scientists have determined the speed and power of volcanic activity, studied with the help of Autonomous underwater vehicle place of eruption. At a depth of 1220 meters was discovered 4.5 km Caldera is a large depression formed by collapse of the upper part of the volcano inside. At the bottom of the Caldera was up to 14 openings through which ejected lava, ashes and pumice.

In the entire history of observations of the eruption of the Havre became the strongest among underwater volcanoes. At the same time, researchers estimate, it was half as powerful than the explosion of the ground of the volcano St. Helens in 1980, the strength of which is estimated at five points out of eight on a scale of volcanic activity VEI.

As reported Корреспондент.netpreviously, scientists discovered at the bottom of the Pacific giant megavolcano Tamu, which in size is comparable to Britain or c with the Mars mount Olympus is the biggest volcano in the Solar system.

The diameter of megavolcano Tamu is about 625 km, and the height is 4 km away. It has not erupted for 140 million years.
