Mount Bulusan

Bulusan

Stratovolcano · Philippines · 1535m

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.

Geological summary

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.

From Wikipedia

Mount Bulusan, also known as Bulusan Volcano, is a stratovolcano on the island of Luzon in the Philippines. Located in the province of Sorsogon in the Bicol Region, it is 70 kilometres (43 mi) southeast of Mayon Volcano and approximately 390 kilometres (240 mi) southeast of Manila. Bulusan is one of the active volcanoes in the Philippines. The 1818 census showed 1,777 native families paying tribute and they were coexisting with 19 Spanish-Filipino families in the area.
