Magnitude 7.8 earthquake strikes southern Philippines with tsunami warnings
Consensus Summary
A magnitude 7.8 earthquake struck the southern Philippines near General Santos City on Mindanao island at 7:37am local time on June 8, 2026, triggering tsunami warnings and causing significant damage. The quake, which occurred 13km southwest of the city, killed at least one person and injured four others, while collapsing buildings and triggering power outages. Tsunami waves up to 3 metres were possible in parts of the Philippines, with smaller waves expected in Indonesia, Malaysia, and other nearby regions. Authorities urged coastal residents to evacuate to higher ground, and Indonesia ordered evacuations in northern areas. The earthquake was felt as far as Indonesia’s North Sulawesi and North Maluku provinces, and aftershocks up to magnitude 6.1 followed. The Philippines, located on the Pacific Ring of Fire, is highly vulnerable to seismic activity and typhoons, with about 20 tropical storms hitting the archipelago annually.
