지질학적 요약
Palinuro seamount in the Tyrrhenian Sea north of the Eolian Islands rises nearly 3,000 m to within 70 m of the surface and has an open summit crater. A marine ash layer (PL-1) radiocarbon dated (calibrated) at 9,990 +/- 90 years ago is chemically and stratigraphically similar to two ash layers on land in southern Italy; it was tentatively correlated to Palinuro seamount activity (Siani et al., 2004).
Wikipedia 요약
영어 요약Palinuro Seamount is a seamount in the Tyrrhenian Sea. It is an elongated 50–70 km (31–43 mi) long complex of volcanoes north of the Aeolian Islands with multiple potential calderas. The shallowest point lies at 80–70 m (260–230 ft) depth and formed an island during past episodes of low sea level. Palinuro was active during the last 800,000 years and is likely the source for a 10,000 years old tephra layer in Italy. Ongoing seismicity occurs at the seamount, which may be a tsunami hazard. The volcanic activity may somehow relate to the subduction of the Ionian Sea farther east.
