Geological summary

Hydrophones in the North Atlantic Ocean recorded signals from an explosive eruption in the South Atlantic along the Walvis Ridge about 780 km NE of Tristan da Cunha Island (Haxel and Dziak, 2005). The signals occurred from November 2001 to March 2002 from the N flank of a seamount 170 km NW of Wüst seamount and 100 km WNW of Rachel seamount (named by the Walvis Ridge MV1203 Expedition). The signals, similar to those produced by a 2001 submarine eruption of Kick 'em Jenny volcano in the West Indies, reached a peak on 19-20 December 2001.
