This image captured May 14, 2022, by NASA's Landsat 9, shows a plume of discolored water being emitted from the 'Sharkcano,' an underwater volcano that lies about 15 miles south of Vangunu Island.
A “fascinating” eruption is approaching as a sleeping giant underwater volcano stirs with seismic activity near America’s west coast.. The seismic activity of Axial Seamount, a submerged ...
The good news is that because the top of the volcano is still 4,500 feet below ... It last erupted in 2015 but has a history of more than 50 different eruptions over the last 800 years ...
The presence of water can greatly alter the characteristics of a volcanic eruption and the explosions of underwater volcanoes in comparison to those on land. For instance, water causes magma to cool and solidify much more quickly than in a terrestrial eruption, often turning it into volcanic glass. The shapes and textures of lava formed by ...
Kilauea began erupting around 2:30 a.m. Monday morning local time at the base of the Halemaumau Crater within the summit caldera after elevated seismic activity was detected overnight.
The first record of the volcano was in 1939, [6] although it must have erupted many times before that date. On 23–24 July 1939 an eruption broke the sea surface, sending a cloud of steam and debris 275 m (902 ft) into the air and generating a series of tsunamis around two metres (6.6 ft) high when they reached the coastlines of northern Grenada and the southern Grenadines.
The 1998 eruption of Axial Seamount was preceded by several large earthquake swarms, common indicators of volcanic activity. The swarms correlated to magma movements in the volcano; bottom pressure recorders deployed on the volcano between 1987 and 1992 recorded five instances of deflation in the summit surface (caused by lava movement ...
A volcano on an uninhabited island in the Galapagos has begun erupting, lighting up the nighttime sky as lava tumbled down its sides toward the sea. The La Cumbre volcano on Fernandina island ...
