BackgroundThe 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 horseshoe-shaped crater breached to the east at the summit of 840-m-high Mount St. Catherine. Pyroclastic-flow deposits extend to the 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 north of Grenada, is listed separately in this compilation along with adjacent submarine and subaerial cones that may represent a single volcanic complex. No eruptions of St. Catherine are known in historical time, although 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 1000 years old. Hot springs and fumaroles are present at several locations on Mount St. Catherine.
