Landslides, tension cracks, slumps, rocks rolling downslopes were among the findings of the on-going monitoring and assessment of the areas affected by earthquake that consecutively occurred in October 16, 29 and 30, 2019 in Mindanao.

It was accordingly caused by 6.3 magnitude earthquake in October 16 and was aggravated during the 6.6 magnitude earthquake in October 29. It was recommended that the affected houses will be immediately relocated since the area is highly susceptible to landslide.

In Purok Talisay, Brgy. Kiagot, there were reported cases of rock rolling downslope. Loose cobble to boulder-sized volcanic rock fragments were observed along the slope. The MGB team recommended for conduct of further assessment and for the relocation or temporary evacuation of household directly situated in the area as it is highly susceptible to mass movement.

Series of tension cracks was also observed in So. Bandera, Brgy. Balabag. A slump was further noted with a maximum vertical displacement of 30 cm.

Another landslide was observed approximately 2 kilometers northeast of the Purok Centro. Adjacent to the landslide crown, series of tension cracks were also observed.

Several areas of Brgy. Goma were also affected. In So. Kiola, a tension crack with a vertical displacement reaching up to 45 cm was noted which imposes threat to the 2 houses that are adjacent to it. It was accordingly occurred in October 30 earthquake.

In Purok Alom, So. Nodila, a massive landslide was observed wherein possible debris flow may pose a threat to damming of Napan River.


As the LGU also prioritizes assessment of earthquake impacts in schools, the MGB team surveyed two (2) schools in Brgy. Palma Gil wherein structural cracks were observed. In Gatong Elementary School- Igang Extension, it was remarked for temporary termination of four (4) classrooms and for inspection of proper authorities.

In Gatong Elementary School, aside from the structural cracks on walls, gap between the wall of a classroom to the floor was also noted as well as a vertical displacement on the floor outside the classrooms in its old building. The MGB team recommended for immediate inspection and assessment by the appropriate authorities.

The MGB-XI’s above-mentioned update covers November 7-8, 2019 monitoring and assessment in close coordination with the Provincial Environment and Natural Resources Offices (PENROs), Local/Municipal Disaster Risk and Reduction and Management Offices (L/M DRRMO) and Philippine Institute of Volcanology and Seismology or PHIVOLCS.


Environmental Warriors’ ideas laid through paper and lens

11-22 makakalikhasan contest winners

As the DENR XI believes in the power of youth’s profound and innovative ideas in matters of environmental protection, it once again conducted the “MakakaLIKHAsan” an Essay and Photo Contest. It is a two-day annual event that aims to earn the active participation and engagement of young environmental warriors through their piece of writing and photo material.

The essay writing revolves in the theme “One Planet. One Nation: Sustaining Green Actions for a Safer Climate.” to which, the New Corella National High School bagged the top place.

Its writer, Mary Chris D. Agarma, states in her piece entitled “Code Green: Diagnosing the Vital Signs of the Earth” that “we [people] are the leukocytes of the Earth and must work hand in hand as a nation and as a planet to protect the only home we have. The earth has long been diagnosed of a severe disease. Like treating chronic illness, necessary measures must be applied.” Strict implementation of environmental laws, reforestation and to look for other sources of renewable energy to not exhaust biofuel are among the writer’s recommendations.

The champion ended her piece with a diagnosis that the earth is “severely destructed, in need of immediate attention, care and restoration.”

For the photo contest, the Ateneo de Davao University which held the championship for two (2) consecutive years has once again bagged the top place. For this year, its entry was photographed by Anton Miguel Balagot with an engraved caption “Carbon Sequestration: A Quest for Life.”

Congratulations to all the participants- our young and creative environmental warriors and to their supportive coaches!

The DENR XI is looking forward to having you again.
