CALAMBA CITY, LAGUNA, Jan. 15 — The Department of Environment and Natural Resources in Calabarzon (DENR-R1V-A) has identified 59 areas prone to landslides and 57 areas susceptible to flooding in the Southern Tagalog region.

DENR-Calabarzon executive director Reynulfo Juan over the weekend told newsmen that based on the geo-hazard assessment made by the Mines and Geosciences Bureau, the areas found to be prone to landslides in Cavite province are Tagaytay City and the municipalities of Maragondon, Ternate, Silang, Alfonso.

Juan said in Laguna province, areas prone to landslides are Calamba City and the towns of Los Baños, Alaminos, Rizal, Nagcarlan, Majayjay, Famy, Mabitac, Sta. Maria, Siniloan, Kalayaan, Cavinti and Paete.

The critical areas in Batangas are Laurel, Mataas na Kahoy, Cuenca, Lipa City, Tuy, Calaca, Mabini, San Juan, and Rosario; while Antipolo City, the towns of Taytay, Rodriguez, San Mateo, Angono, Binangonan, Cardona, Morong, Baras, Tanay, Pililia and Jala-Jala are the landslide prone area in Rizal province, he said.

Juan said in Quezon provonce, the areaas are General Nakar, Infanta, Real, Mauban, Panukalan, Burdeos, Pagbilao, Atimonan, Lopez, Buenavista, Mulanay, San Andres, San Fransisco, Tagkauayan, Sampaloc, Dolores, Tayabas, Lucban and General Luna.

He said the areas found to be highly susceptible to flooding are the municipalities of Kawit, Noveleta and Cavite City in Cavite province; Mabitac, Santa Maria, Famy, Siniloan, Pangil, Pakil, Paete, Kalayaan, Lumban, Cavinti, and Sta.

The DENR Calabarzon office has urged provincial governors and city and municipal mayors in the region’s five provinces to brace for the worst amid the erratic weather pattern.

Juan also urged barangay residents in Calabarzon, especially those living in low lying areas and along creeks and rivers and waterways to be vigilant at all times, especially during continuous heavy rains.

The Region IV-A director said that as part of the government’s national greening program to help prevent future calamities, the regional agency will embark on a project to rehabilitate thousands of hectares forest land in Calabarzon this year.

“DENR RIV-A is rehabilitating the forests—planting and nurturing the trees that buffer the rain, absorb the excess water and prevent run-offs and flood,” Juan said.

He also urged all LGUs in the region to use geohazard maps prepared by the Mines Geoscience Bureau (MGB) to prevent calamities similar to what happened in areas devastated recently by Tropical Storm “Sendong.

MGB Director Leo Jasareno had announced earlier the government’s geohazard maps will soon be posted at the website of Environmental Science for Social Change (www.essc.org.ph) indicating areas considered high risks.

Geohazard maps are seen to boost efforts of provincial and municipal disaster risk reduction management councils to prevent the massive effects of natural calamities, especially on the lives and safety of residents.

Juan said in the geohazard map, the color-coded natural hazards—landslides, floods and flash floods are superimposed on the topographic map of the Philippines, from the provincial down to the municipal and barangay levels.

Geohazard maps produced by DENR are also available at the regional office’s Decision Support Systems Office and at the regional office of the regional director in Calamba City, he said.

The geohazard maps could serve as warning to disaster-prone areas and as a guide to prevent catastrophes in the region, Juan added. (PNA)
