JUST IN (updated 10:48 a.m.): Phivolcs reported this morning that Kanlaon, Bulusan, Taal, and Mayon Volcanoes are under Alert Level 1, which means that abnormal activity has been recorded in all four volcanoes. MANILA, Philippines — A total of 19 volcanic earthquakes shook Bulusan Volcano in Sorsogon province in the past 24 hours, the Philippine Institute of Volcanology and Seismology (Phivolcs) said Bulusan’s worst eruption involving lava flows and landslides lasted from 1918 to 1922. Three small craters are located on the SE flank. Meanwhile, Solidum said the public should avoid entering the 4-kilometer radius Permanent Danger Zone (PDZ). A cloud of steam and ash shot from Mount Bulusan, into the air to a height of 5 kilometres and drifted, to be deposited over the surrounding countryside. There were ten explosions up until 28th June 2006. The seismic network around Bulusan Volcano recorded 28 volcanic earthquakes during the past 24 hours. Steaming activity was wispy to moderate and reached an approximate height of 50 m above the summit before drifting WNW. Located about 390 kilometers (244 miles) southeast of Manila, Bulusan is the southernmost volcano on Luzon Island. PHIVOLCS noted that this may mean "volcanic processes" are happening underneath the volcano. The event was recorded as an explosion-type earthquake and lasted approximately 16 minutes, PHIVOLCS said.
