More than 200 barangays have been warned on the possible landslides, flooding, and storm surges taking a cue from a warning issued by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) that a tropical storm ‘Ruby’ is expected to enter into the Philippine Area of Responsibility (PAR) today.
“We need to send a strong message to the local government executives to undertake the necessary preemptive evacuation efforts in low-lying and landslide-prone areas in Bohol, Cebu, Negros Oriental and Siquijor as yet another typhoon has entered the country which could bring a lot of rains,” said Mines and Geosciences Bureau (MGB) 7 Regional Director Loreto B. Alburo.
Although tropical storm ‘Ruby’ has been described as less powerful than super typhoon “Yolanda” that struck the Visayas which caused heavy damage to property and massive loss of lives, Alburo said that being prepared always or even “overprepared” would be the better option if only to ensure the safety of the communities who may be affected.
“There are factors that contribute to flooding which includes proximity to perennial river creek system, poor drainage facility, inherently low lying area, proximity to coastal area, heavily silted river or creek, and encroachment along natural drainage channels,” sad Department of Environment and Natural Resources (DENR) 7 Regional Executive Director Dr. Isabelo R. Montejo.
Flooding occurs when the level of a body of water rises until it overflows its natural or artificial confines and submerges land in the surrounding area due to intense and prolonged precipitation and other geologic factors.
“Our mayors and barangay captains should keep on areas that are found to be highly susceptible to flooding and landslides which have been known to them as indicated in the geohazards threat advisory issued to them,” Alburo stressed.
Storm surge-prone areas are Arpili, Balamban; Tungkil, Minglanilla; Talisay, Maricaban, and Kinatarcan, all in Santa Fe; Tarong, Mancilang, and Codia, all in Madridejos; Patao and Pitogo in Bantayan; and Tanke in Talisay City.
He also urged local chief executives to get hold of the geohazard maps, and implement the necessary measures to reduce the impact of landslides and flooding within their areas of responsibility.
Montejo warned that the volume of water brought by Ruby might aggravate soil conditions that have been either saturated by rains or loosened by trees uprooted by Queenie, thereby causing landslides.
Meanwhile, in Cebu City , 19 barangays are highly susceptible landslides, namely, Lusaran, Binaliw, Guba, Budlaan, Malubog, Buot-Taup, Busay, Sirao, Taptap, Tagbao, Tabunan, Pung-ol Sibugay,Sudlon II, Sudlon I, Sinsin, Buhisan, Pamutan, Sapangdaku, and Adlaon.
