At that time the vent of the volcano was below sea level, but frequent eruptions ejected molten lava up to 70 m (230 ft) above sea level, and sulfurous steam plumes up to 500 m (1,600 ft). The team mapped a roughly conical feature rising from 1,100 m (3,600 ft) water depth, with the volcano having a basal diameter of about 8 km (5.0 mi).

The tsunami was triggered by a landslide rather than a volcanic eruption. Estimates of the dead start at 539 while another 700 were reported missing.
Submarine volcanoes are underwater vents or fissures in the Earth's surface from which magma can erupt. Many submarine volcanoes are located near areas of tectonic plate formation, known as mid-ocean ridges. The volcanoes at mid-ocean ridges alone are estimated to account for 75% of the magma output on Earth. [1]

A known parasite is the tapeworm Lithobothrium gracile, which infests the shark's spiral valve intestine. The carcass of a 3.7-m-long (12.1 ft) female found off Fuerteventura in the Canary Islands contained a number of snubnosed eels (Simenchelys parasitica) inside her heart, body cavity, and back muscles. Whether the eels contributed to the ...
