Mount Saint Catherine

The island of Grenada is composed of five Pliocene-to-Pleistocene volcanic centers, the youngest and highest of which is Mount St. Catherine on the northern end of the island. A complex of lava domes is located within a crater breached to the east at the summit. Pyroclastic-flow deposits extend NW from the extensively weathered volcano. The most recent activity on Grenada originated from a group of young maars, tuff rings, and scoria cones that extend SSW-NNE across the length of the 30-km-long island. Kick 'em Jenny, the historically active submarine volcano 8 km N of Grenada, is listed separately in this compilation along with adjacent submarine and subaerial cones that may represent a single volcanic complex. The most recent eruption, along a NE-SW-trending fault cutting across the island, produced a scoria cone near Radix village that could be less than 1,000 years old. Hot springs and fumaroles are present at several locations.
