The Kavachi volcano in the Solomon Islands, one of the most active submarine volcanoes in the Pacific Ocean and one of the most famous for its shark inhabitants, is showing increased plums, according to the American space agency NASA. The underwater volcano has been dubbed the “sharkano” after two species of sharks were discovered in an active hole during a 2015 expedition.
On Twitter, the National Aeronautics and Space Administration (NASA) shared satellite images of volcanic eruptions under the sea. Images show fading water erupting from the Kavachi volcano, about 24 kilometers south of Bhangunu Island, on May 14. Images taken by Operational Land Imager 2 of the Landsat 9 satellite
In 2015, scientists found hammerhead sharks living in the warm, acidic waters of the Kawachi Volcano underwater crater. ‘Sharkano’, as they call it, is exploding again. https://t.co/l4Exv5GZXypic.twitter.com/XS7QBHxqCw

According to NASA’s Earth Observatory, the Kavachi plate was formed by tectonics and began to explode in October last year. The new satellite data suggests several days of activity in April and May 2022. Studies have shown that these plumes of superheated, acidic water usually contain particulate matter, volcanic rock fragments and sulfur.

However, this is not a problem for resident sharks as large marine animals are able to survive in extreme environments by tolerating hot and acidic waters. The U.S. space agency said in 2015 that researchers found a scalloped hammerhead and a silky shark among the many species of fish living in active volcanoes. Experts believe that sharks must have evolved to survive in hot and acidic environments
Returning to the volcano, NASA said that the last major eruptions were observed in Kavachi in 2014 and 2007. But the space agency added that it erupted almost uninterruptedly, and residents of nearby settlements often reported visible vapors and ash.

The first report of its activity was recorded in 1939. Since then, there have been at least 11 significant eruptions that were so powerful that they created a new island. “But the islands, up to a kilometer long, have been eroded and swept away by the action of the waves,” NASA said.
The peak of the volcano is currently estimated to be 65 feet below sea level. Its base is located at a depth of 1.2 km below sea level.
