Lava flow forces thousands to evacuate
State volcanologists raised the alert level on the 8,070-foot Mayon volcano overnight to two steps below a major eruption after ash explosions.
Dark orange lava fragments glowed in the dark as they trickled down the mountain slope overnight. Renato Solidum, head of the Philippine Institute of Volcanology and Seismology, said the activity could get worse in coming days.
