The danger named ‘Sharkcanoe’ hovering under the sea can explode anytime, NASA warns!

Kavachi Volcano in the Solomon Islands is one of the most active submarine volcanoes in the Pacific Ocean. NASA is also looking serious about this. According to the Smithsonian’s Global Volcanology Program, the volcano entered the eruptive phase in October 2021, after which satellite data showed that the waters around Kawachi had changed color for several days between April and May 2022.

NASA’s Earth Observatory has released one of its blog shared a photo taken by Operational Land Imager-2 (OLI-2) on Lansat 9 on May 14, 2022, showing discolored water emanating from a submarine volcano. This muddy water is seen spreading for several kilometers.

one made in 2008 Study But shedding light, the blog states that such plumes of superheated, acidic water typically contain particulate matter, fragments of volcanic rock, and sulfur. A 2015 scientific expedition to the volcano found that this submerged crater is home to two species of sharks, one of which is the hammerhead shark. In addition, at that time researchers also found that there were microbial growing in sulfur.

The survival of the shark in such circumstances certainly brought many new questions for the researchers regarding the ecology of active submarine volcanoes. About these questions and their research, researchers in 2016 published Wrote in an oceanographic article titled Exploring the “Sharkcano”.

Prior to this recent activity, Kawachi had seen major eruptions in 2007 and 2014. The Earth Observatory’s blog notes that the volcano erupts continuously, and residents of nearby inhabited islands often report visible steam and ash.

Since its first recorded eruption in 1939, Kawachi has created ephemeral islands on several occasions, but ocean waves eroded these islands up to a kilometer long. The summit of the volcano is currently estimated to be 20 meters (65 ft) below sea level and its base is located at a depth of 1.2 kilometers (0.75 mi) at sea level.

The blog says that Kawachi formed in a tectonically active area. The volcano produces lava, ranging from basaltic rich in magnesium and iron to andesitic rich in silica. It is known to be a fretomagmatic eruption in which the interaction of magma and water causes large eruptions, ejecting steam, ash, fragments of volcanic rock.
