Trails of steam in the foreground rise from floating scoriacious blocks during a submarine eruption off the west coast of Socorro Island in 1993. The eruption, from vents about 3 km NW of Punta Tosca, was first observed January 29, 1993 following ten days of SOFAR signals recorded in Hawaii. Large scoriaceous blocks up to 5 m in size floated to the surface without associated explosive activity. Floating masses of hot scoria were continuously erupted until at least the end of February 1994.
