Reduced volcanic activity recorded at Kick ’em Jenny off Grenada

St George’s, Grenada — The Seismic Research Centre (SRC) at the University of the West Indies has recorded reduced activity levels at the Kick em’ Jenny submarine volcano 10 km (6 miles) off the north coast of Grenada, following the two small eruptions recorded last week.

Recreational divers have reported seeing some “degassing” on the seafloor off Grenada’s coast as gas-rich magma bubbles.

If this trend continues, a decision will be made to lower the alert level. However, the Orange alert level currently remains in effect.

The Kick ’em Jenny volcano was rumbling on Thursday and regional disaster authorities were put on alert, though they said it posed no threat of triggering a destructive tsunami. Since its discovery in the 1930s, Kick ’em Jenny has erupted beneath the surface of the Caribbean Sea at least 12 times, most recently in 2001. The volcano, which rises 1,300 meters (4,265 feet) above the seafloor on a steep slope of the Lesser Antilles ridge, has not caused any known deaths or injuries.

However, Kick ’em Jenny is of great concern to local governments. Past eruptions during the last century (1939, 1965) resulted in observed deep water tsunamis, with the one in 1939 being measured at 1m (3ft) high.
