The major tectonic plates found around the Philippines are:
- The Philippine Sea Plate , located to the east of the Philippine archipelago. It is an oceanic plate that subducts westward beneath the Philippine Mobile Belt along the Philippine Trench and East Luzon Trough
- The Eurasian Plate (Sunda Plate) , situated to the west of the Philippines. This plate subducts eastward beneath the Philippine Mobile Belt along trenches such as the Manila Trench, Negros Trench, Sulu Trench, and Cotabato Trench
- The Philippine Mobile Belt , a complex tectonic zone or microplate that covers most of the Philippine archipelago itself. It is situated between the Philippine Sea Plate to the east and the Eurasian Plate to the west and experiences east-west compression due to the opposing subduction zones
- Additionally, the Pacific Plate lies further east and subducts beneath the Philippine Sea Plate at the Izu–Ogasawara Trench, influencing regional tectonics
- The Caroline Plate and Bird's Head Plate are located to the south of the Philippine Sea Plate, near the southern boundary of the Philippine region
In summary, the Philippines is situated at a complex convergent boundary involving the Philippine Sea Plate to the east, the Eurasian Plate (Sunda Plate) to the west, and the Philippine Mobile Belt in between, with additional influence from the Pacific Plate and smaller plates to the south. This tectonic setting results in multiple subduction zones and active fault systems, making the region highly seismically active
