A devastating 7.8 magnitude earthquake struck the southern Philippines on Monday morning, claiming at least 32 lives and injuring over 200 people across multiple provinces. The powerful tremor, which hit at 7:37 a.m. local time, triggered a 3-foot tsunami that reached nearby coastal areas, causing widespread damage to buildings and infrastructure. The offshore quake’s epicenter was located approximately 20 miles southwest of Maasim town in Sarangani province, at a depth of 20 miles beneath the ocean floor. Tsunami waves were recorded as far away as Indonesia, Palau, and southern Japan, though the threat subsided approximately five hours after the initial tremor.
General Santos, a major port city with over 700,000 residents and a regional hub for tuna exports, bore the brunt of the disaster. Several low-rise buildings collapsed entirely, while dozens more sustained severe structural damage. The city’s international airport was forced to shut down temporarily, resulting in the cancellation of 17 domestic flights. Search and rescue teams worked frantically to locate survivors potentially trapped beneath a supermarket, warehouse, grade school, and other commercial structures that crumbled during the quake. At least 12 people remained missing in the city as emergency crews continued their efforts throughout the day.
Deadly landslide claims 13 lives in Sarangani province
The earthquake triggered a catastrophic landslide in Glan municipality, located in Sarangani province, killing 13 villagers in a matter of minutes. Rene Punzalan, a provincial disaster-mitigation official, confirmed the deaths during an interview with DZBB radio network. Four additional fatalities were reported elsewhere in Sarangani province, bringing the regional death toll to 17. The landslide buried homes and blocked access roads, complicating rescue operations in the mountainous terrain. Provincial authorities mobilized heavy equipment to clear debris and search for potential survivors trapped beneath tons of earth and rock.
Most of the other confirmed deaths resulted from building collapses and falling debris throughout South Cotabato and Davao Occidental provinces, as well as on Balut Island. A damaged mosque was among the structures that claimed lives when it partially collapsed during the tremor. Emergency responders reported that many victims were inside buildings when the earthquake struck, giving them no time to evacuate to safety. The structural failures highlighted concerns about building codes and earthquake preparedness in the region, particularly for older constructions not designed to withstand major seismic events.
Tsunami waves measured across Pacific region
Coastal monitoring stations recorded tsunami waves reaching 3 feet in Sultan Kudarat and Sarangani provinces, with a peak measurement of 4.6 feet registered at one point in Kiamba town. The Pacific Tsunami Warning Center tracked wave activity throughout the region, detecting an 83-centimeter wave off Indonesia’s Sulawesi island and 30-centimeter waves reaching Palau. Japan’s Meteorological Agency reported waves up to 20 centimeters hitting the remote island of Chichijima and the central town of Kushimoto. Six shanties built on stilts in a coastal village in Zamboanga del Sur province were damaged by the combination of the earthquake and higher-than-normal waves that swept through the area.
The tsunami warning issued immediately after the earthquake remained in effect for several hours as authorities monitored wave patterns and assessed coastal damage. Philippine officials lifted the warning by mid-afternoon once wave heights returned to normal levels and the immediate threat passed. Coastal residents who had evacuated to higher ground were allowed to return to their homes, though authorities cautioned them to remain vigilant for potential aftershocks that could trigger additional waves.
Schools and communities face widespread disruption
The earthquake transformed what should have been an exciting first day back to school after a two-month summer break into a traumatic experience for hundreds of students. More than 100 uniformed students and a dozen teachers had gathered for a flag-raising ceremony at a grade school in the rural town of Malita when the ground began shaking violently. School principal Rosavel Cachuela described the chaotic scene as young children screamed in panic and some wept in fear. Fortunately, most students remained seated and still, preventing injuries despite the terror they experienced. A motorcycle was damaged when a shed collapsed in the school compound, but no students or teachers were hurt.
President Ferdinand Marcos Jr. immediately ordered the cancellation of classes throughout affected provinces and directed disaster-response agencies to mobilize resources for emergency operations. The president emphasized that the national government would provide full support to Mindanao, stating that affected communities would not be left to face the crisis alone. The DZRH radio network reported that a four-story commercial building housing its provincial station partially collapsed, though staff members managed to evacuate to the ground floor without injuries.
International support and seismic context
The United States confirmed it was coordinating with Manila and stood ready to support Philippine response efforts under the countries’ mutual defense treaty. France and New Zealand also expressed solidarity and offered assistance to help with relief operations. Teresito Bacolcol, director of the Philippine Institute of Volcanology and Seismology, identified the earthquake as the strongest to hit the Philippines this year and warned residents to seek professional advice before returning to damaged structures that could collapse during aftershocks.
The Philippines ranks among the world’s most disaster-prone nations due to its location on the Pacific Ring of Fire, an arc of seismic faults encircling the ocean where tectonic plates meet. The archipelago experiences frequent earthquakes and volcanic eruptions as a result of this geological positioning. Rod Sosmeña, a regional director of the Office of Civil Defense, was traveling in General Santos when the earthquake struck. He initially thought his pickup truck had a flat tire before realizing the vehicle was shaking from the tremor. Residents across affected areas reported feeling intense shaking that sent people running from buildings into streets for safety.
Emergency response continues amid infrastructure damage
Disaster-response agencies worked throughout the day to assess the full extent of damage across southern Mindanao, the second most populous island in the Philippine archipelago. Emergency crews prioritized search and rescue operations in areas where people were believed to be trapped, while medical teams treated the more than 200 injured victims at hospitals and makeshift treatment centers. The disruption to transportation networks, including the temporary closure of General Santos International Airport, complicated efforts to deliver supplies and reinforcements to affected communities.
Authorities established evacuation centers for residents whose homes were destroyed or deemed unsafe for habitation. The earthquake’s impact on critical infrastructure, including roads, bridges, and utilities, raised concerns about the timeline for recovery in hardest-hit areas. Engineers began conducting structural assessments of damaged buildings to determine which could be safely repaired and which would require demolition. The government mobilized additional resources to support local authorities overwhelmed by the scale of the disaster, as communities began the long process of recovery and rebuilding.
