Most of the casualties come from collapsing or damaged buildings in the Mindanao region, where videos already show cracked structures and debris-strewn streets.
The quake’s epicentre sits about 32 kilometres south-west of Maasim town in Sarangani province at a depth of 33 kilometres beneath the sea, according to the Philippine Institute of Volcanology and Seismology. The Pacific Tsunami Warning Centre reports the tsunami threat largely subsides around five hours after the initial shock.
Coastal areas near the epicentre see waves of about one metre, but national officials say there are no confirmed tsunami-related casualties or property losses so far.
Emergency teams across Mindanao focus on assessing damaged buildings and treating hundreds of injured residents pulled from homes, shops and offices. Local authorities lean on video footage and on-the-ground inspections to gauge structural safety and decide which areas need evacuations or cordons.
Monitoring networks from the Philippine institute continue to track aftershocks and evaluate the risk of further slides or collapses, especially in older or already weakened structures.
The Philippines sits squarely on the seismically active Pacific “Ring of Fire”, which leaves the country exposed to major tectonic events. Disaster agencies now look likely to use this event to refine evacuation protocols, building checks and public warning systems across the southern region.
