The country’s vulcanology and seismology institute, Phivolcs, said the explosions of ash occurred at Mayon volcano, about 200 miles southeast of Manila.
Large amounts of sulfur dioxide gas were also being emitted by the volcano, according to Phivolcs.
The institute said Tuesday’s blasts sent ash soaring about 2,300 feet above the crater, but the debris did not affect any nearby communities or farms.
Mayon is known for its almost perfect cone shape, and has erupted about 50 times since modern record keeping began in 1616.
A violent eruption of Mayon in 1814 killed more than 1,200 people when volcanic mud buried a town. The volcano spewed lava during its last significant activity in July 2006.
