Ambrym Volcano, Vanuatu - John Seach

A large amount of gas is currently being emitted by Ambrym volcano, Vanuatu, especially from the beginning of October until December. Volcanic gas measurements on 17th December 2009 show that there were 15,000 tonnes of sulphur dioxide emitted. During an expedition to Ambrym volcano by John Seach from 5-14 December 2009, there were large amounts of gases visible in the craters of Marum, Benbow, Niri Mbwelesu, and Mbogon Niri Mbwelesu. A decent into Benbow crater showed lava visiible in one vent, and also in Mbwelesu crater on the eastern side of Marum. Acid rain is a potential hazard for communities living on the island.
