Description

Marsili is a large undersea volcano in the Tyrrhenian Sea, about 175 kilometers south of Naples. The seamount is about 3,000 meters tall, its peak and crater are about 450 meters below the sea surface. Though it has not erupted in recorded history, volcanologists believe that Marsili is a relatively fragile walled structure, made of low density and unstable rock, fed by the underlying shallow magma chamber.
