Grenada has 2 Holocene volcanoes. Note that as a scientific organization we provide these listings for informational purposes only, with no international legal or policy implications. Volcanoes will be included on this list if they are within the boundaries of a country, on a shared boundary or area, in a remote territory, or within a maritime Exclusive Economic Zone. Bolded volcanoes have erupted within the past 20 years. Suggestions and data updates are always welcome ().

Chronological listing of known Holocene eruptions (confirmed or uncertain) from volcanoes in Grenada. Bolded eruptions indicate continuing activity.

There are 3 photos available for volcanoes in Grenada.

A Sonar image shows the submarine Kick-'em-Jenny cone from the NE in 1996. Depths are nominally meters but have an uncertainty of about 10%. This image shows the upper several hundred meters of the submarine volcano that lies 8 km off the north shore of Grenada and rises 1300 m from the sea floor. Numerous historical eruptions, mostly documented by acoustic signals, have occurred since 1939 and involve both explosive activity and the quiet extrusion of lava flows and lava domes.

Image by Doug Martin, 1996 (NOAA, courtesy of Seismic Research Unit, University of West Indies). The southern end of the elongated Mount St. Catherine volcanic complex on the island of Grenada is seen here from the Southeast Mountain area. The island is composed of five Pliocene-to-Pleistocene volcanic centers, the youngest and highest of which is 840-m-high Mount St. Catherine on the northern end of the island. The most recent activity originated from a group of young maars, tuff rings, and scoria cones extending across the length of the island. These include Grand Etang crater, which lies near the crest of the skyline ridge.

Photo by Richard Arculus, 1973 (Seismic Research Unit, University of West Indies). Vertically exaggerated SeaBeam image shows Kick 'em Jenny and newly identified craters and domes discovered in March 2003. Kick 'em Jenny's summit occurs adjacent to the crater rim at a depth of ~ 185 m. The deepest point on Kick 'em Jenny's crater floor lies at ~264 m depth. The image's left side is drawn N-S (i.e. N towards the upper left). Tick marks along the margins are at 0.01 degree intervals, a spacing equivalent to 1.8-1.9 km. The distance between Kick 'em Jenny and Kick 'em Jack is about 4 km.
