The threat of the Philippines' Taal volcano unleashing a potentially catastrophic eruption remains high, authorities warned Thursday, saying it was showing dangerous signs despite a "lull" in spewing ash.
Scores of earthquakes rattle the region daily and large fissures are opening up in the ground, which means the magma that would fuel a major eruption is still flowing beneath.
Authorities are struggling to keep evacuees, some 50,000 of whom fled to shelters after Taal burst to life on Sunday, away from the danger zone around the volcano.
People are trying to get back to homes they left in a hurry to get a change of clothes, feed livestock and pets and check on properties damaged by the fissures or covered with a thick layer of ash.
"Please allow us to observe the lull period for now. We are studying what that means," Maria Antonia Bornas, a scientist from the Philippines' seismology agency told reporters.
"A long lull could be just a break from volcanic activity," she said. "The danger remains."
