The Philippines is bracing for a possible three-month-long emergency in areas around an erupting volcano, which has already displaced more than 81,000 and led to overcrowded temporary shelters, the disaster agency said on Friday.
Mount Mayon in central Albay province remained at alert level 4, a notch below the highest level, as it continued to spew lava, ash and other superheated material, volcanologists said."We're gearing up for three months" of emergency, said Romina Marasigan, spokeswoman of the country's disaster agency, citing similar situations during previous eruptions of the 2,462-metre (8,077-foot) volcano.
Displaced families may need to stay in evacuation centres for that long, she said.
Food and other supplies remain adequate but concerns are growing over health and hygiene conditions at all the 69 temporary shelters away from the danger zone.
Respiratory illnesses are possible because of the series of ash falls, she said.
Volcanologists said there were seven more episodes of intense but sporadic lava fountaining at the crater lasting several minutes during a 21-hour period from Thursday morning.
The lava fountains, shooting up between 150 m. (492 ft) and 500 m. (1,640 ft), generated ash plumes that spurted as high as 3 km (1.8 miles) above the crater, they said.
Despite the warnings, some residents have refused to abandon the danger zone, with farmers worrying about leaving crops and cattle unattended, while others split their time between homes and evacuation centres they say are crowded and uncomfortable.
