Overview

• USGS measured a magnitude-7.4 offshore earthquake near Manay in Davao Oriental around 9:43 a.m. local time at roughly 58 km depth, while Phivolcs initially cited 7.6.
• A significant later quake around magnitude 6.7 struck the same region about ten hours after the mainshock, and Phivolcs reported roughly 480 aftershocks, describing the sequence as a potential doublet.
• The Pacific Tsunami Warning Center initially forecast waves of 1–3 meters within 300 km and issued regional alerts for Indonesia and Palau, but only minor fluctuations were observed before warnings were lifted.
• Officials reported at least six deaths, building damage, landslides and power outages, and ordered coastal evacuations and class suspensions across several provinces as emergency teams mobilized.
• On Oct. 11, USGS recorded a magnitude-6.0 quake near Surigao del Sur with no immediate casualties reported, as the government maintained rescue operations and infrastructure checks.
