At least 35 people have lost their lives and more than 200 others have been injured after a powerful 7.8-magnitude earthquake struck the southern Philippines on Monday, causing widespread destruction and triggering tsunami warnings across parts of Southeast Asia.

The earthquake struck off the southern coast of Mindanao island at a depth of around 33 kilometres, according to seismic authorities. The tremor was the strongest recorded in the Philippines this year and was felt across several provinces.

Buildings collapse as rescue efforts continue

Authorities reported significant damage in and around General Santos City, where several buildings were damaged or collapsed. Videos circulating on social media showed structures crumbling as residents rushed to safety.

Officials said at least 12 people remain missing, while rescue teams continue searching through debris. Reports also indicated that some students may have been trapped after a school building collapsed during the quake.

Landslides add to the devastation

The earthquake triggered landslides in several areas, including Sarangani province, where multiple villagers were killed. Other deaths were reported due to falling debris and structural collapses in South Cotabato, Davao Occidental and nearby islands.

Emergency responders have been deployed to affected regions, while local authorities assess the full extent of the damage.

Tsunami threat eases

Following the earthquake, tsunami warnings were issued in the Philippines and Indonesia, prompting coastal residents to move to higher ground. However, officials later confirmed that the tsunami threat had largely passed.

The largest tsunami wave recorded in the Philippines measured 1.4 metres, with no reported tsunami-related casualties.

Strong reminder of Pacific Ring of Fire risks

The Philippines and Indonesia lie along the Pacific “Ring of Fire”, one of the world’s most seismically active zones. Both countries experience frequent earthquakes and volcanic activity due to shifting tectonic plates.

Authorities have urged residents to remain alert as aftershocks continue to be recorded in the region.
