Philippine volcano calm only for now

The Mayon volcano's crater glows as it emits lava in Legazpi City, Albay province, south of Manila December 29, 2009. The Philippine government's vulcanologists said on Sunday that the Mayon volcano has been calm over the weekend but warned the public not to be complacent because there could be an explosive eruption soon due to the clogging of magma inside and the swelling of its surface.
