Monitoring Kick ‘em Jenny

Grenada has two volcanoes – Mt. St. Catherine and Kick ‘em Jenny. Kick ‘em Jenny is an undersea volcano located 8 km north of the island. It reaches a depth of approximately 180 meters. The volcano has erupted 12 times since 1939.

The University of the West Indies Seismic Research Center has assigned a yellow alert level for the volcano indicating that “the volcano is restless: seismicity and/or fumarolic activity are above the historical level, or other unusual activity has been observed, or can be expected without warning.” Given the risk, a monitoring network has been established.

The network is depicted in the figure above.

Given the close proximity of the volcano to Grenada, the possibility of a tsunami reaching the shores of Grenada in less than five minutes after an eruption can be threat to Grenadian life and property depending on the size of the wave generated.

There are no historical records of eruptions of Mt. St. Catherine. Earthquake risk is considered moderate to low, classified in seismic zone 2 under a 4 zone system. However an eruption of Kick Em Jenny does have the potential to produce a significant earthquake which can affect the state. Read more
