10 June 2006, 8:00 A.M.
An ash explosion occurred at 12:18 A.M. from the summit crater of Bulusan Volcano (12° 46’N, 124° 03’E). The explosion produced an ash and steam cloud which rose to about one (1) kilometer above the volcano’s summit and drifted generally Northeast and East affecting mainly Barangays San Isidro, Sta. Barbara, Buang and Purog in Bulusan Municipality. The initial ash explosion was recorded by all monitoring stations around the volcano although no volcanic earthquake preceded the explosion event.
This is the 6th explosion to occur since Bulusan Volcano spewed ashes last 21 March. Since then, PHIVOLCS has noted the increasing frequency in ash emissions and expects more explosions to occur. Alert Level 2 remains in effect which means that the area within four (4) kilometers of the summit is off-limits. In addition, areas within the Northeast and Eastern sectors should expect more ashfall with succeeding explosions due to prevailing winds. As before, additional precautions should be observed for areas near river channels because ash and other loose deposits from the upper slopes may be remobilized into life-threatening volcanic flows.
