|Big sinkhole in a farm lot in Dumanhug, Cebu
MANILA, Philippines – A big sinkhole in a farm lot in Dumanhug town, Cebu continues to draw onlookers from neighboring towns of Barili and Ronda.
The sinkhole, located in Barangay Camboang, measures at least 10 meters wide and almost 4 meters deep.
Authorities said activity is being monitored at the sinkhole, which may still widen.
Water is also spotted coming out of the sinkhole, leading geologists to suspect that there may be an underground river at the bottom of the hole.
Philippine Institute of Volcanology and Seismology (Phivolcs) will inspect the sinkhole to determine if it poses a threat to the residents in the area.
The local government is also planning to ask assistance from international experts.
A sinkhole is a hole in the ground caused by the chemical dissolution of carbonate rocks, usually due to circulating ground water.
Phivolcs is also observing activity at the shore of Dumanhug in Cebu after residents claimed that they spotted "boiling water" rising out of the seafloor. -- With a report from Rico Lucena, ABS-CBN News Central Visayas
