MGB drawing up flood hazard vulnerability risk maps of Kalibo, Aklan

ILOILO CITY, July 13 –The Mines and Geosciences Bureau (MGB) is preparing a flood hazard vulnerability risk maps of Kalibo, Aklan.

“The flood hazard vulnerability risk maps would reflect data on the number of barangays, total populations, infrastructures, etc. that will be affected by flooding. In line with this, a software is currently being developed by MGB-Central Office together with the DOST and PAGASA,” said Supervising Geologist Mae Y. Magarzo of the MGB Region 6. The same activity will also be conducted in Bago City, Negros Occidental.

MGB 6 continuously conducts information dissemination side-by-side with their mapping activities among the municipalities in the region.

On July 22-24, an Information, Education and Communication (IEC) campaign will be conducted by the MGB, Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), National Mapping and Resource Information Authority (NAMRIA) and Philippine Institute of Volcanology and Seismology (PHIVOLCS) under the READY Project or “Hazard Mapping and Assessment for Effective Community-Based Disaster Risk Management” in the province of Antique.

READY Project is an Australian Aid-funded program, implemented by the United Nation Development Programme (UNDP), through the National Disaster Risk Reduction Management Council–Office of the Civil Defense (NDRRMC-OCD) and its CSCAND Partners (PAGASA, MGB, NAMRIA, PHIVOLCS). The READY Project was implemented in 2006 and operationally closed in 2012.

The final multi-hazard maps at 1:50,000 scale produced under the READY Project were formally turned over to the provincial government of Antique. One component of the project is the conduct of IEC campaign in order to cascade hazards information to the barangay level and capacitate community leaders in implementing activities and measures for disaster reduction.

The workshop after each hazard presentation will enable participants to be aware of their community’s vulnerability to certain hazards and help them formulate a plan of action to mitigate the negative impacts in terms of lives and socio-economic losses in their community.

Participants to the IEC workshop are local chief executives, PDRRMO, PPDC, PEO, PHO, PSWD, DILG, MDRRMO, MPDC and barangay captains or their representatives.

The recent monsoon rains brought by typhoon Egay have triggered landslides in various towns in Central Iloilo. In 2011, half of Brgy. Cawilihan in Leon, Iloilo was destroyed by torrential rains caused by Typhoon Nina which caused the relocation of the barangay and its residents.

“The towns of Igbaras, Alimodian, Tubungan, Leon, Cabatuan and even Maasin are highly susceptible to landslides and flooding. In fact, Brgy. Uminggan, one of the barangay in the “7 cities” of Alimodian, has to be relocated due to its vulnerability to landslide in its former location,” Magarzo said.

Local chief executives and residents, however, are already aware of the hazards of landslides and flooding in their respective areas. They were also guided by the MGB on possible relocation sites as indicated in the geohazard map.

Meanwhile, the Groundwater Resource Vulnerability Assessment and the Georesistivity surveys are also being conducted by the MGB to assess the quality of the groundwater and to determine the depth and thickness of acquifer using the newly acquired Georesistivity Meter. Target areas for this year are the municipality of Kalibo, Aklan and Bago City, Negros Occidental. (PNA)
