Monte Aso

Asosan

Caldera · Japan · 1592 m

The 24-km-wide Aso caldera formed during four major Pleistocene explosive eruptions. These produced voluminous pyroclastic flows that swept over much of Kyushu. A group of 17 cones was constructed in the central part of the caldera, seen here from the ENE caldera rim. The Nakadake cone is one of Japan's most active volcanoes with recorded eruptions dating back to 553 CE.

Sintesi geologica

The 24-km-wide Asosan caldera was formed during four major explosive eruptions from 300,000 to 90,000 years ago. These produced voluminous pyroclastic flows that covered much of Kyushu. The last of these, the Aso-4 eruption, produced more than 600 km3 of airfall tephra and pyroclastic-flow deposits. A group of 17 central cones was constructed in the middle of the caldera, one of which, Nakadake, is one of Japan's most active volcanoes. It was the location of Japan's first documented historical eruption in 553 CE. The Nakadake complex has remained active throughout the Holocene. Several other cones have been active during the Holocene, including the Kometsuka scoria cone as recently as about 210 CE. Historical eruptions have largely consisted of basaltic to basaltic andesite ash emission with periodic strombolian and phreatomagmatic activity. The summit crater of Nakadake is accessible by toll road and cable car, and is one of Kyushu's most popular tourist destinations.

Sintesi da Wikipedia

Riassunto in inglese

Mount Aso or Aso Volcano is the second largest active volcano in Japan after Mount Fuji, and among the largest in the world. Common use relates often only to the somma volcano in the centre of Aso Caldera. It stands in Aso Kujū National Park in Kumamoto Prefecture, on the island of Kyushu. Its tallest peak, Takadake, is 1,592 meters (5,223 ft) above sea level. Mount Aso is in a fairly large caldera with a circumference of around 120 km (75 mi), although sources vary on the exact distance. It is one of the 100 Famous Japanese Mountains.
