Sinkhole Discovered Following Negros Earthquake

DUMANJUG, Cebu -- The Mines and Geo-Science Bureau (MGB) Region 7 has recommended the installation of fence, warning signs, and continuous monitoring of a sinkhole in a farm in Barangay Camboang in this town.

Authorities said the sinkhole was discovered following the earthquake two weeks ago that rocked Negros Oriental.

Senior Police Officer 1 Joselito Abella said sinkhole was eight meters in diameter and six meters deep as of 4 p.m. Friday but authorities expect this to become larger and deeper as the soil continues to erode

Farm caretaker Walter Pesalbon discovered the sinkhole in the 2.7-hectare farm reportedly owned by a certain Joy Distelkamps.

Earlier, Dumanjug Mayor Nelson Garcia had already ordered the police and barangay watchmen to guard the area and make sure people aren't allowed inside the fenced farm.

Meanwhile, MGB 7 sent a geologist to conduct a site assessment on the reported sinkhole in Sitio Plaza, Barangay Camboang, which is roughly three kilometers from the municipal hall in Dumanjug, southwest of Cebu.

MGB7 Senior Science Research Specialist Abraham R. Lucero Jr. said the collapse or cave-in of the cave roof which resulted to the formation of a sinkhole may have been trigged by the 6.9 magnitude earthquake and many aftershocks, and intense and prolonged precipitation brought about by an active low pressure area.

''The earthquake may have caused ground or tension cracks. These factors may have weakened the cave roof,'' he said.
