Other residents have also questioned the ground-penetrating-scanning (GPS) conducted by MGB on Poblacion Uno.
Doris D. Tan, a Boholana who is convinced of the looming danger in said place, wrote: “If there is a gaping sinkhole in the midst or very near my home and a report has been released by the authorities that this opening is an entrance of not just a single cave but a honeycombed caves, would I still wait for my government to tell me what to do?â€
“It is the same way that during an earthquake and even at its aftermath, people refuse to go back to their houses and opt to live in tents for fear that the next aftershock will bring their houses down on them. And nobody ordered them to do that. It is the instinct of self preservation. So, if there is a great probability that the ground under my feet will at anytime give in, what do you think will I do?â€
Sinkholes, according to Britannica Encyclopedia, is defined as a “topographic depression formed as underlying limestone bedrock is dissolved by groundwater. It is considered the most fundamental structure of karst topography.â€
“Sinkholes vary greatly in area and depth and may be very large. There are two main varieties, one caused by the collapse of the roof of a cavern, the other by the gradual dissolving of rock under a soil mantle. Collapsed sinkholes generally have steep rock sides and may receive streams that then flow underground. The soil-mantled sinkhole is generally shallower than the collapsed sinkhole and receives local drainage; it may become clogged with clay and hold a small lake. Some sinkholes, formed at low sea-level stages during the Pleistocene epoch, are now half-drowned and are known as cenotes,†the resource book said. (MIKE ORTEGA LIGALIG)
