Source: Yahoo! Over 100 sinkholes found in southwestern Bohol The Mines and Geosciences Bureau (MGB) has found over 100 sinkholes in the southwestern part of quake-hit Bohol. In an interview with ANC, MGB Director Leo Jasareno said they are expecting to find more sinkholes once they finish mapping by the end of the year. However, this does not necessarily mean the province is no longer safe to live in, he clarified. “The collapse of a sinkhole would depend on many factors. You may have a sinkhole but if the capping, yung ibabaw na between sinkhole and lupa, is thick or overlain by another rock na matibay, thats okay. The problem is if the capping becomes thin enough so that rupture will happen.” Meanwhile, Jasareno also expressed concerns over a sinkhole in Panggangan Island in Bohol which is directly underneath a school. “In Panggangan island, where we found about a tunnel, underground, it’s about 100 meters. Fortunately, the sinkhole is in middle of school grounds. What is dangerous there is that there are tension cracks, which means that while sinkhole has collapsed, rupture is still in progress. Lalaki pa siya. And considering that our radar has found out that there is really a tunnel underground about 100 meters. That is dangerous,” he explained. Jasareno added, though, that the school may have to be relocated soon. “We will be coordinating with the schools so that they will be informed and be advised properly what to. I think we can say that relocation in necessary.”READ MORE: Death toll in Bohol quake reaches 218
