MGB-CAR INITIAL SURVEY SHOWS SHIFT IN APAYAO-ABULOG RIVER
The Mines and Geosciences Bureau- Cordillera Administrative Region (MGB-CAR) in an attempt to assist the Provincial Mining Regulatory Board of Apayao in regulating the excavation activities along the banks of the Apayao-Abulog River, initiated a drone survey of the river on April 12-13, 2023. Initial results of the survey showed a shifting of the river to as much as 2 kilometers to the east at one point.
The shift was determined by the team led by MGB-CAR’s chief geologist Benigno Cesar Espejo through a comparison of the drone results and a satellite image (Sentinel 2. January 2023) with the NAMRIA Topographic Map of 1979.
This determination is crucial in identifying areas to restore the river’s flow into the right courses and avoid further erosion along river banks. The team further recommended suitable and possible areas for quarrying and dredging that will aid in ensuring the right path of the river flow.**Sheila Sanqui
