Vulcan is a pumice cone in Papua New Guinea.It is a sub-vent of the Rabaul caldera and lies on the western rim of the larger
feature.Its most recent eruption was in 1994, when in
conjunction with another vent, Tavurvur, the
eruptions of Vulcan forced the abandonment of the city of Rabaul
and the relocation of the local administrative centres of East New Britain
Province, to a new capital, Kokopo.
