Light ashfall was reported 5 km N and trace amounts as far as 20 km N.The Alert Level was raised to 2 (scale 0 to 5), which means restricted entry within 4 km of the summit. On 10 June, an ash-and-steam cloud reached a height of ~1 km above the summit (8,400 ft a.s.l.) and drifted N and NE. A newsarticle reported one death caused by an asthma attack from exposure to ash.

Bulusan volcano in the Philippines came back to life on Tuesday 21st of March 2006. At around 23h00 local time (16:00 GMT) the volcano spewed a column of ash nearly a mile (1.5 kilometres) into the sky. The Philippine Institute of Seismology and Vulcanology (Phivolcs) said the ash was unlikely to cause any harm, but warn that the volcano may be about to erupt more powerfully. A four-kilometer (2.4-mile) exclusion zone is already in place around the 1,565-meter (5,133-foot) volcano, which is 600 kilometers (370 miles) southeast of Manila. The institute will be closely monitoring the volcano for further activity. Bulusan had a series of similar explosions in 1994 and 1995....mehr
