Disaster risk reduction planning of local government units should take into consideration the new fault lines discovered by the Philippine Institute of Volcanology and Seismology in Negros, Vice Gov. Eugenio Jose Lacson said yesterday .
“That discovery will be a guide to all LGUs for contingency plans,” he said.
“For sure nothing should be built on top of those fault lines. If there are structures on top of those fault lines, a decision has to be made to leave the place or enhance the structures in those areas,” he added.
The Provincial Disaster Management Program Division is reviewing its contingency plans in the light of the recent discovery of new fault lines in Negros, PDMPD head Zeaphard Gerhart Caelian said Thursday.
A fault line is a long crack in the surface of the earth. Earthquakes usually occur along fault lines, he said.
Fault lines are potential earthquake generators, Caelian added.
Personally he hopes the “big one” will never happen here in Philippines, especially Negros Occidental, Lacson said.
The result of the 2017 Phivolcs mapping shows the presence of the East Negros Fault System that includes the San Carlos fault, Calatrava-Toboso fault, Bindoy-Guihulngan fault, and Pamplona-Manjuyod fault, Caelian said.
Identified as potentially active are the Pontevedra-Hinigaran trace, Sibulan fault and Candoni fault, he said.
Previously existing in the Phivolcs map were only the Central Negros and Southern Negros faults, he said.*CPG
