Thirteen villagers in the town of Glan, Sarangani province, were buried when a landslide tore through their community in the aftermath of a magnitude 7.8 earthquake that struck the southern Philippines on June 8, 2026. Provincial disaster-mitigation official Rene Punzalan reported the Glan deaths to DZBB radio, making the landslide one of the single deadliest incidents in a disaster that has killed at least 35 people across the region. Three days later, isolated villages still lack reliable road access, and local officials have called for emergency food airlifts as government assessment teams work to reach cut-off areas.
Aftershock landslides, not shaking alone, drove Glan’s death toll
The initial tremor was centered in Maasim, Sarangani, but the worst loss of life in Glan came not from collapsing structures but from the hillside that gave way and engulfed residents. That distinction matters because it points to a pattern: successive ground movement loosened saturated slopes, and the resulting slides blocked the roads that rescue crews needed. The Office of Civil Defense deployed a Rapid Damage Assessment and Needs Analysis team to Glan and the broader Sarangani area, prioritizing the restoration of communications links severed by debris. Yet the very terrain that rescuers must cross keeps shifting, a feedback loop that slows every stage of the response.
Glan’s 13 confirmed buried villagers account for more than a third of the at least 35 fatalities attributed to the earthquake across the affected zone. That concentration suggests the landslide, rather than building collapses spread across multiple towns, was the primary killer. Confirming this fully would require matching aftershock timestamps from PHIVOLCS with the time-stamped incident logs that the Department of Social Welfare and Development has been publishing. DSWD’s disaster-response monitoring unit has so far released sequential situation reports since June 8, each updating casualty and displacement figures, but none of the publicly available summaries break down fatalities by village or by the specific trigger, whether primary shaking or secondary landslide.
Local officials say the Glan slide followed a series of aftershocks that continued to rattle the province after the main quake. Residents who survived described hearing a deep rumble before the slope failed, giving them only moments to flee. Emergency workers arriving on foot have had to navigate unstable ground while carrying stretchers and limited medical supplies, complicating both search operations and the retrieval of bodies for identification.
Because the landslide buried homes rather than toppling multi-story buildings, the usual visual cues of urban earthquake damage are largely absent. From a distance, parts of the affected sitio appear as a raw scar of mud and rock, with only fragments of roofing or household items visible. That has made it harder for authorities to quickly verify how many structures were occupied at the time of the slide, and whether some residents may have been away at work or in nearby markets when the hillside collapsed.
Government response stretched thin between energy checks and food shortages
Within hours of the earthquake, the Department of Energy activated its Task Force on Energy Resiliency to coordinate with power utilities and fuel distributors across Sarangani. The activation signals concern that generation facilities, transmission lines, or fuel depots sustained damage, though no public utility log has yet detailed exact outage durations or the scope of infrastructure harm. For residents in landslide-isolated barangays, the absence of electricity compounds an already dire situation: without power, water pumps fail, communication towers go dark, and cold-chain storage for medicine breaks down.
President Ferdinand Marcos Jr. ordered the temporary suspension of classes in earthquake-affected areas, a step documented by the Presidential Communications Office. That directive freed school buildings for use as evacuation shelters and removed children from structures whose integrity had not yet been certified. The decision also signaled to local governments that national agencies recognized the severity of the event, opening channels for faster resource requests and allowing school-based relief centers to organize food distribution and basic health services.
On the ground, the gap between official deployments and actual aid delivery has been stark. Glan officials have publicly sought immediate airlifts of food to reach communities where landslides have made road transport impossible. The call for airlifts reveals that conventional supply chains, trucks moving along provincial roads, have failed. Debris fields from multiple slides block key routes, and clearing operations compete for the same heavy equipment needed for search and rescue at burial sites.
Local disaster councils are attempting to stretch pre-positioned relief stocks, but those caches were sized for more routine flooding or storms, not for a high-magnitude earthquake followed by widespread slope failure. With fuel supplies uncertain, even small boats and motorcycles that might bypass blocked roads are operating on tight rations. Community volunteers have resorted to hand-carrying sacks of rice and bottled water along footpaths where vehicles cannot pass, a labor-intensive workaround that cannot meet the needs of thousands of displaced residents.
Coordination between national and local agencies hinges on accurate, timely information. The Philippine Information Agency serves as a key conduit for official updates, and its documents are accessible through the government’s freedom of information portal. But the speed of the disaster has outpaced the publication cycle of many formal reports, leaving mayors and barangay captains to rely on radio communications and ad hoc messaging apps to flag urgent shortages before they appear in national dashboards.
What the Glan landslide data still cannot answer
Several questions remain open as the response enters its fourth day. First, the exact number of people still missing beneath the Glan landslide has not been confirmed by any national agency in a public document. Punzalan’s account to DZBB radio is the most specific attribution available, and field conditions may have prevented a precise headcount. Second, DSWD situation reports do not yet include granular, village-level breakdowns that would allow independent verification of how many of the 35 confirmed deaths occurred in Glan versus other municipalities. Third, no official statement from the Office of Civil Defense or the National Disaster Risk Reduction and Management Council has addressed food stock levels in isolated villages or provided a timeline for airlift logistics.
The energy picture is similarly incomplete. The DOE’s task force activation confirms institutional awareness of the risk, but the absence of published damage assessments from individual utilities means the public cannot gauge when power will return to affected areas. For families sheltering in evacuation centers or in the open, that uncertainty translates directly into questions about safety, health, and how long they will need to remain displaced. Health workers warn that extended blackouts can quickly undermine sanitation and refrigeration for vaccines, raising the risk of disease outbreaks in crowded shelters.
Another blind spot involves the stability of slopes that have not yet failed. Geologists typically need days to conduct field mapping and aerial surveys to identify other hillsides at risk of collapse. Until those assessments are complete, residents living below steep terrain face the dilemma of whether to stay in damaged homes or move to evacuation centers that may already be full. Local officials in Glan and neighboring towns have begun issuing precautionary advisories during heavy rain, but without detailed hazard maps, these warnings remain broad and sometimes difficult to act on.
The next development to watch is the release of DSWD’s seventh situation report and any updated field assessment from the OCD team now on the ground in Sarangani. Those documents should begin to clarify whether additional landslide sites exist beyond Glan, how many people remain unaccounted for, and what volume of food and non-food items is required to sustain isolated communities over the coming weeks. They may also offer the first systematic picture of damage to power and water systems, giving residents a clearer sense of when basic services will be restored.
For now, Glan stands as the most tragic symbol of how secondary hazards can magnify the toll of a major earthquake. The buried homes on its unstable slopes, the blocked roads that delay help, and the incomplete data that constrain planning all point to the same lesson: in a mountainous, disaster-prone country, preparedness must extend beyond building codes to encompass landslide mapping, redundant supply routes, and rapid, transparent information-sharing between national agencies and the remote communities most at risk.
