Observations and sampling of an ongoing subsurface eruption of Karachi volcano, Solomon Islands, May 2000

A serendipitous encounter with an erupting, shallow submarine volcano in the Solomon Islands provided a rare opportunity to map and sample the dispersal of volcanogenic emissions into the surrounding water column.

Description
Summary:A serendipitous encounter with an erupting, shallow submarine volcano in the Solomon Islands provided a rare opportunity to map and sample the dispersal of volcanogenic emissions into the surrounding water column. Kavachi, episodically active since at least 1939, is a forearc volcano located on the Pacific plate only approximately 30 km northeast of its convergent boundary with the downgoing Indo-Australian plate. During 14 May 2000 we observed explosive phreatomagmatic eruptions at several minute intervals, creating a complex distribution of plumes of volcanic glass shards throughout the water column at a distance of approximately 1.5 km from the summit. At distances of 4-5 km, shallow-water (
