Galunggung

Stratovulcano · Indonesia · 2168 m

The low, forested volcano of Galunggung in western Java has a 2 x 6 km collapse scarp formed by a large flank collapse that created the "Ten Thousand Hills of Tasikmalaya" at the foot of the volcano. Historical eruptions have been infrequent but have caused extensive devastation. This view shows the low Gunung Jadi cone in front of the headwall scarp and lahar channels on the Cikunir River from the 1982-1983 eruption.

Sintesi geologica

The forested slopes of Galunggung in western Java SE of Bandung are cut by a 2-km-wide collapse scarp open towards the ESE. The "Ten Thousand Hills of Tasikmalaya" dotting the plain below the volcano are debris-avalanche hummocks from the collapse about 4,200 years ago. An eruption in 1822 produced pyroclastic flows and lahars that killed over 4,000 people. A series of major explosive eruptions starting in April 1982 destroyed a number of villages, killed as many as 30 people, and forced over 60,000 to evacuate. Pyroclastic flows and heavy widespread ash caused significant damage. A large passenger jet that encountered the ash plume on 24 June lost power to all four engines but managed to land safely in Jakarta. The 1982 activity destroyed a 1918 dome and formed the Warirang crater, almost as wide as the valley, about 2 km down from the summit.

Sintesi da Wikipedia

Il Galunggung è un stratovulcano attivo presente sull'isola di Giava, a circa 80 km da Bandung, capoluogo della provincia di Giava Occidentale, in Indonesia. Appartiene all'Arco di Sonda, che attraversa Sumatra, Giava e Bali ed è prodotto dalla subduzione della placca australiana sotto quella euroasiatica.
