MGB underscores the need for vigilant monitoring of Itogon

In a presentation to small scale miners of Itogon on October 17, 2018 during Secretary Cimatu’s visit, Mines and Geosciences Bureau (MGB) emphasized the need for vigilant monitoring of their areas.

During the dialogue, Ms. Liza Socorro Manzano, Supervising Science Research Specialist , presented the results and highlights of the geohazard assessment the MGB team conducted in Itogon relative to the landslide that occurred in Ucab on September 15, 2018.

Assessment results showed that the massive landslide was triggered by abnormally high rainfall brought about by Typhoon Ompong.  PAGASA in Baguio City recorded a total of 785.8 mm of rainfall in 48 hours which was equivalent to almost two months of rainfall. 

Ms Manzano added that since this is now the “new normal”, we are to be vigilant and expect more weather disturbances like this.

Furthermore, the Ground Penetrating Radar survey and drone mapping have shown that landslides in the area are active as indicated by progressing tension cracks, bulging of slope face, seepages and heaving in concrete structures.

With these results, the bureau strongly recommended for the immediate relocation of small scale mining communities in areas delineated in critical zone with active landslides especially those in places found to show signs of being active.

The concept of Minahang Bayan is applicable in some areas but permanent habitation or settlement within the area of mining operation should not be allowed.

Relocation plans and programs should be implemented the soonest possible time to avert disaster that may result to loss of more lives and damage to properties.

Until such time that these recommendations are seriously considered and implemented, people of the municipality are called upon to be vigilant and ready to evacuate when there are impending weather disturbances.
