This spectacular video of an erupting undersea volcano recently came through the geoscience grapevine, and thought I would share it here. Enjoy!
According to the anonymous voice accompanying the video, the volcano is Kavachi (9.02° S 157.95° E), near the Solomon Islands. The eruptive history of Kavachi has been recorded since 1939 and numerous periods of volcanism have been documented in that time. Although the date of this video is uncertain, the most recent known eruption occurred in early April 2007 following a magnitude 8.1 earthquake. Kavachi has emerged above the ocean surface to form an island on nine occasions, only to subside again due to erosion.
