St. Catherine massif is the youngest of the five volcanoes on the island. The volcano has a ~1.5-km horseshoe-shaped crater open to the east, where a complex of volcanic lava domes occur across its flanks and is monitored by the Seismic Research Center of the University of the West Indies. The volcano is considered dormant because it has likely not erupted since the last Ice Age.
