The Philippine Space Agency (PhilSA) has released satellite-based maps identifying landslide-affected areas triggered by the June 8 Mindanao earthquake.
According to PhilSA, earthquake-induced landslides were detected in several barangays in Glan, Sarangani, including Calabanit, Ilaya, San Vicente, Congan, and Calpidong. Additional landslide sites were mapped in the barangays of Butuan, Patulang, Sugal, Nuing, San Isidro, and Batulan in Jose Abad Santos, Davao Occidental.
The agency estimated that approximately 137.87 hectares may have been affected by landslides.
PhilSA said the assessment was conducted by comparing pre-disaster satellite images taken on June 1, 2026, with post-disaster images captured on June 14, 2026, using the European Space Agency’s Sentinel-2A and Sentinel-2B satellites. Areas of vegetation loss were identified through significant declines in the Normalized Difference Vegetation Index (NDVI), a key indicator used to monitor land cover changes.
The agency noted that the findings remain subject to ground validation.
PhilSA added that the satellite data provides extensive coverage that supports the National Disaster Risk Reduction and Management Council (NDRRMC) in monitoring affected areas and prioritizing response efforts.
“PhilSA will continue monitoring satellite data as the situation requires,” the agency said.
Meanwhile, the NDRRMC reported that the death toll from the earthquake has decreased to 76 based on its latest situation report released Friday.
More than 1.45 million people across Mindanao remain affected by the disaster. As of June 19, authorities recorded 348,579 affected families, equivalent to 1,453,372 individuals, across Regions IX, XI, XII, and the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM).
The earthquake also caused significant damage to homes, public infrastructure, and other facilities in the affected regions
