The quake, the strongest to hit the Philippines this year, struck off the coast of Mindanao island at 7:37 a.m. local time, causing widespread panic and disruption across several southern provinces.

Authorities said the death toll rose after at least 17 fatalities were reported in Sarangani province, where a landslide buried homes in the mountainous town of Glan.Rene Punzalan, a disaster mitigation official in Sarangani, said 13 villagers were killed in the landslide, while four others died elsewhere in the province.

The new casualties brought the overall death toll from the earthquake to at least 32.The earthquake damaged buildings, disrupted transportation and displaced thousands of residents. Philippine disaster officials said most fatalities were caused by collapsing structures, landslides and falling debris across the provinces of Sarangani, South Cotabato, Davao Occidental and nearby Balut Island.
