Mon 8 Jun 2026 at 10:51amMon 8 Jun 2026 at 10:51amA powerful magnitude-7.8 earthquake has shaken the Mindanao region in the southern Philippines, with a tsunami possible on some regional coasts.At least one person has been killed and four people have been injured, local police told AFP."Many buildings were affected, but I cannot enumerate them now because we are busy with ongoing rescues," Master Sergeant Robert Dagon of the General Santos City police said."A number of buildings collapsed. Some houses also collapsed."Power outages were reported and people were urged to go to higher ground.The epicentre was 13 kilometres south-west of General Santos city on the island of Mindanao and had a depth of 10 kilometres, according to the Philippine Institute of Volcanology and Seismology.It struck at 7:37am, on Monday, local time.The Pacific Tsunami Warning Center (PTWC) said tsunami waves up to 3 metres were possible on some coasts of the Philippines. Waves up to 1 metre were possible on some coasts of Indonesia and Malaysia."We advise people to evacuate to higher grounds or go further inland," Teresito Bacolcol, the head of the Philippine institute, warned people living in coastal areas.The PTWC said smaller tsunami waves were possible in Taiwan, Japan, Guam, Papua New Guinea and several island nations and territories in the western Pacific.There was no threat to Hawaii or the American mainland coast, the PTWC said.Residents felt the earthquake tremors in Indonesia's North Sulawesi and North Maluku provinces.Aftershocks up to magnitude-6.1 followed, the US Geological Survey said.It measured the original quake at 55 kilometres deep. Variations in measurements by different agencies are common in the immediate aftermath of an earthquake.The Philippines, one of the world's most disaster-prone countries, is often hit by earthquakes and volcanic eruptions due to its location on the Pacific Ring of Fire, an arc of seismic faults around the ocean.The archipelago is also lashed by about 20 typhoons and tropical storms each year.AP/AFP
