unnamed submarine VulkanA submarine volcano is located 118 km SE of Manus Island in the Bismarck Sea. The volcano was detected through acoustic signals probably produced by a submarine eruption in January 1972. The signals were similar to those from known submarine eruptions and recorded at seismic stations on nearby Mauns Island and at hydrophones on Wake and Midway Islands in the Central Pacific.
Beschreibung:The volcano is located at the junction of 2 segments of the northern margin of the South Bismarck plate. The eastern of these segments is a transform fault, whereas the western segment is an area of oblique active seafloor spreading.
