[THIS IS A PRESS RELEASE]
The Philippine Space Agency (PhilSA) is currently analyzing available satellite data on the 7.8-magnitude earthquake that struck Mindanao on 8 June 2026.
Differences in nighttime satellite imagery from 8 June at 1:30 AM and 9 June at 1:12 AM show areas that have less nighttime light. Changes in nighttime light provide a means to rapidly assess damage, disruption, and recovery after disasters. When lights go out, it often signals power loss, infrastructure damage, or population displacement/evacuation.
This preliminary analysis presents a proxy of where the most damage is located based on the absence of nighttime light. Barangays Labangal, Apopong, San Isidro, City Heights, and coastal barangays of Siguel and Tambler of General Santos City (722,059 population based on 2024 PSA Census); coastal municipalities Maasim (67,907 residents) and Glan (117,017 residents) in Sarangani; and Polomolok, South Cotabato (176,671 residents) are some of the areas that showed a decrease in nighttime light based on visual comparison.
PhilSA is in the process of refining and improving this analysis towards identifying the affected areas. The return of nighttime lights may also be used as a proxy to monitor reconstruction and recovery.
PhilSA’s support through the analysis of satellite data provides wide-area coverage that assists the National Disaster Risk Reduction and Management Council (NDRRMC) in monitoring the situation and prioritizing areas for response. By making space data accessible to stakeholders, PhilSA enables informed decision-making and strengthens disaster response.
PhilSA will continue monitoring satellite data as the situation requires. Please follow local and national agencies for the latest advisories.
