MANILA, Philippines (AP) 鈥 A restive Philippine volcano briefly erupted Tuesday on a central island, sending a 4-kilometer (2.4-mile) plume of ash and debris into the sky and forcing authorities to suspend school classes in four villages due to ashfall, officials said.
There were no reports of injuries or damage from Mount Kanlaon鈥檚 latest eruption after dawn that lasted more than an hour and scattered ash in at least four farming villages southwest of the volcano on Negros island, the Philippine Institute of Volcanology and Seismology said.
Kanlaon , prompting the evacuation of thousands of villagers, many of whom remained in emergency shelters on Tuesday as the volcano continued showing signs of restiveness, the Office of Civil Defense said.
Philippine chief volcanologist Teresito Bacolcol told The Associated Press there were no other key signs of restiveness, like a spike in volcanic earthquakes, that would prompt the alert on Kanlaon to be raised from the current level 3, which means a 鈥渉igh level of volcanic unrest." The highest alert, level 5, means a 鈥渉azardous eruption is in progress.鈥
鈥淭he possibility of a bigger eruption is always there,鈥 Bacolcol said, urging people to remain vigilant and stay away from a 6-kilometer (3.7-mile) danger zone around Kanlaon.
The 2,435-meter (7,988-foot) volcano is one of the country鈥檚 24 most active volcanoes. In 1996, three hikers were killed near the peak and several others were later rescued when Kanlaon erupted without warning, officials said then.
The Philippines is located in the so-called Pacific 鈥淩ing of Fire,鈥 a region prone to earthquakes and volcanic eruptions. The archipelago is also lashed by about 20 and storms a year, making it one of the world鈥檚 most disaster-prone countries.
