Pantelleria Vulkan

Pantelleria ist einer der weniger bekannten aktiven Vulkane Italiens. Er bildet eine kleine gleichnamige Insel südlich von Sizilien. Sein letzter (und einzig historisch bekannter) Ausbruch fand 1891 unterseeisch statt.

Beschreibung:

Two large Pleistocene calderas dominate the island, which contains numerous post-caldera lava domes and cinder cones and is the type locality for peralkaline rhyolitic rocks, pantellerites. The 15-km-long island is the emergent summit of a largely submarine edifice. The 6-km-wide Cinque Denti caldera, the youngest of the two calderas, formed about 45,000 years ago and contains the two post-caldera shield volcanoes of Monte Grande and Monte Gibele. Holocene eruptions have constructed pumice cones, lava domes, and short, blocky lava flows. Many Holocene vents are located on three sides of the uplifted Montagna Grande block on the SE side of the island. A submarine eruption in 1891 from a vent off the NW coast is the only confirmed historical activity.
