Ringkasan geologi

The Marsili seamount is a 50-km-long volcanic ridge in the southern Tyrrhenian Sea within a back-arc basin about 75-85 km NW of the Aeolian arc volcanoes. Near-source tephra layers obtained from a core sample were determined by Iezzi et al. (2013) to be approximately 3,000 and 5,000 years old. Accretion of the ridge is thought to have begun around 1 Ma. Recent data also indicate that there is ongoing hydrothermal activity and shallow volcano-tectonic seismicity.

Ringkasan Wikipedia

Ringkasan Inggris

Marsili is a large undersea volcano in the Tyrrhenian Sea, it is located approximately 140 kilometers (87 mi) north of Sicily and approximately 150 kilometers (93 mi) west of Calabria. The seamount is about 3,000 m tall; its peak and crater are about 450 m 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 and nearby Mediterranean coastlines.
