normal levels of activities," Solidum said. "At Kanlaon, from time to time there are ash emissions which are not really hazardous except for those right at the crater." At Taal, which tourists often visit to see its crater lake, Phivolcs has recorded increased volcanic earthquakes but "other parametres are not showing any abnormalities yet", he added. Solidum said Phivolcs was not yet recommending any evacuation around the three volcanoes, but urged the public to take precautionary measures. "We advise the public not to go inside the main crater area of Taal," he said. "We also advise the public to cover their noses with masks or handkerchiefs so they will not inhale fine ashes being emitted by Kanlaon from time to time," he added. Kanlaon last erupted in August 1996 but has no destructive eruptions yet. Taal has been quiet since its last eruption in October 1977. Its deadliest eruption was in 1911 when it killed 1,334 people and its ashes reached Manila.
