Scientists say the cone-shaped Mayon volcano in the central Philippines has shot an ash plume into the air and are advising nearby residents to be ready to move in case of eruption.
Chief state volcanologist Renato Solidum says Mayon's alert
level remains the same but that if magma continues to rise below
the glowing crater it could erupt within weeks.
The country's most active volcano last erupted in 2006.
Typhoon-triggered mudslides later that year buried entire villages,
killing more than 1,000 people.
Two explosions early Wednesday sent ash and rocks more than half
a mile (a kilometer) into the air, reaching nearby Camalig town
along Mayon's foothills.
Authorities say they are ready to evacuate villages once the
alert level goes up.
