Monte Bulusan

Bulusan

Stratovulcano · Philippines · 1535 m

Bulusan, seen here from the W, is the southernmost volcano on the island of Luzon. It has formed within the 11-km-wide Irosin caldera along with other cones and domes. Frequent moderate explosive eruptions have been recorded since the mid-19th century from craters at the summit.

Sintesi geologica

Luzon's southernmost volcano, Bulusan, was constructed along the rim of the 11-km-diameter dacitic-to-rhyolitic Irosin caldera, which was formed about 36,000 years ago. It lies at the SE end of the Bicol volcanic arc occupying the peninsula of the same name that forms the elongated SE tip of Luzon. A broad, flat moat is located below the topographically prominent SW rim of Irosin caldera; the NE rim is buried by the andesitic complex. Bulusan is flanked by several other large intracaldera lava domes and cones, including the prominent Mount Jormajan lava dome on the SW flank and Sharp Peak to the NE. The summit is unvegetated and contains a 300-m-wide, 50-m-deep crater. Three small craters are located on the SE flank. Many moderate explosive eruptions have been recorded since the mid-19th century.

Sintesi da Wikipedia

Il Bulusan è uno stratovulcano attivo situato nella regione di Bicol, provincia di Sorsogon, nell'estremità meridionale della grande isola di Luzon nella parte centrale dell'arcipelago delle Filippine. Il vulcano è costituito da un impianto conico principale che sorge sulla caldera di Irosin e sul quale si aprono quattro crateri. Il Bulusan si trova a circa 250 chilometri a sud-est dalla capitale del Paese, Manila, e a 70 km dal vulcano Mayon.
