Kick'em Jenny and her new seismic gear are located just off the coast of the island of Grenada.

Scientists have installed seismic instruments on an underwater volcano known as Kick'em Jenny and located just off the north coast of the island nation of Grenada. The volcano will eventually emerge from beneath the sea to form a new island.

Over time, layers of lava from an underwater volcano can build up and emerge as an island.

Underwater volcanoes can eventually form islands. The process can take hundreds of thousands of years and thousands of eruptions. As each lava flow covers the one before it, enough layers build up to finally emerge from the sea. Researchers are studying just such a volcano called Kick 'em Jenny. They have deployed a Real Time Offshore Seismic Station (RTOSS) to take measurements closer to the action than ever before.
