Philippines braces for emergency as volcano shows alarming activity

LEGAZPI, The Philippines - A volcano that's been erupting for almost two weeks in the Philippines still appears to be swelling with magma under the surface, scientists said on Thursday.

More than 74,000 people are staying in dozens of emergency shelters as Mount Mayon continues to belch lava, ash and superheated gas and rocks. Officials are worried the eruption may last months, affecting the education, health and livelihoods of people in its shadow.

The Philippine Institute of Volcanology and Seismology said tremors, pyroclastic flows and emissions of sulfur dioxide were detected on Wednesday and early Thursday.
