The Department of Environment and Natural Resources (DENR), through its Mines and Geosciences Bureau (MGB) 7 has reiterated its advisory to all the communities who are living nearby or within a mountain or a hill and those along the riverbanks or creeks to be more cautious after heavy rains inundated a number of areas in Metro Cebu yesterday.
Taking a cue from a warning issued by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) that a tropical storm “Mario” is expected to enter into the Philippine Area of Responsibility (PAR) by Friday, MGB 7 Regional Director Loreto B. Alburo issued anew geohazards threat advisories to all local chief executives to keep a close watch on the geohazards map on landslides and flood prone areas.
At 4:00 am today, Pagasa says “Mario” was estimated based on all available data at 460 km East of Catarman, Northern Samar (12.9ºN, 129.1ºE) with maximum sustained winds of 65 kph and gustiness of up to 80 kph. it is forecast to move west northwest at 28 kph.
Alburo said the local government units with the strong support from the communities themselves is the key towards achieving a “zero” casualty when disaster comes.
To facilitate easy access of the geohazards maps, the said maps in a 1-50,000-scale are now available and downloadable in four government websites, including that of a non-government organization.
The government websites hosting the interactive geohazard maps include that of the DENR (www.denr.gov.ph), Mines and Geosciences Bureau (www.mgb.gov.ph), Philippine Information Agency (www.pia.gov.ph) and that of Environmental Science for Social Change (www.essc.org.ph).
“It is very essential for mayors and barangay captains to give more attention of areas that are found to be highly susceptible to flooding and landslides within their areas of responsibility which have been known to them as MGB 7 already released a geohazards threat advisory,” said DENR 7 Regional Executive Director Dr. Isabelo R. Montejo.
Montejo also pushed for the local chief executives to appreciate the geohazard maps, and implement the necessary measures or interventions to lessen the impacts of landslides and flooding.
He warned that the volume of water brought by “Mario” might trigger soil conditions that have been either saturated by heavy rains.
