Introduction
Bulusan is a young andesitic volcano built upon the NE rim of an older dacitic-to-rhyolitic caldera, the 11-km wide Irosin caldera, which was formed about 35,000-40,000 years ago.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 of 1565-m-high Bulusan volcano 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 at Bulusan since the mid-19th century.
