Marsiliとは 意味・読み方・使い方

Marsili is a large undersea volcano in the Tyrrhenian Sea, about 175 kilometers (110 miles) south of Naples. The seamount is about 3,000 meters (9,800 feet) 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 rocks, fed by the underlying shallow magma chamber. Volcanologists with the Italian National Institute of Geophysics and Volcanology (INGV) announced on March 29, 2010 that Marsili could erupt at any time, and might experience a catastrophic collapse that would suddenly release vast amounts of magma in an undersea eruption and landslide that could trigger destructive tsunamis on the Italian coast.
