The small 3 x 4 km conical island of Narcondum volcano, a possession of India, is located in the Andaman Sean about 130 km E of North Andaman Island. The island is densely vegetated, bounded by cliffs on the southern side, and capped by three peaks. Volcanism at the andesitic volcano is considered to have continued into the Holocene (Krishnan, 1957), but the last eruption is unknown. The island's name means "pit of hell," though the name could have been mistakenly transferred from the active Barren Island volcano, 140 km SSW.
