The Philippine Trench is a submarine trench east of the Philippines, reaching depths of 10,540 meters. It is the third deepest trench in the world.

The Philippine Fault Zone (PFZ) is a major left-lateral strike-slip fault that extends for 1,200 km from Luzon to Mindanao. It is one of the most seismically active fault systems in the world.

An oceanic trench west of the Philippines, capable of producing large megathrust earthquakes. It extends from Taiwan to Mindoro and poses tsunami risk to western Luzon.

A submarine trench located in the Celebes Sea, south of Mindanao. It is a subduction zone where the Celebes Sea Plate subducts under the Sunda Plate.

A major fault cutting through the central Philippines, associated with significant seismic activity in the Visayas region.

Part of the Philippine Fault Zone in Central Luzon, responsible for the devastating 1990 Luzon earthquake.

The Marikina Valley Fault System (also known as the Valley Fault System) passes through Metro Manila and nearby provinces. It poses significant risk to the National Capital Region.

A fault system in Negros Island responsible for significant seismic activity in the Central Visayas.

Part of the Marikina Valley Fault System, running along the western edge of the Marikina Valley. It passes through densely populated areas of Metro Manila.

Located in Aurora province, this fault has been responsible for damaging earthquakes in eastern Luzon.

Part of the Marikina Valley Fault System, running along the eastern edge of the Marikina Valley through Rodriguez, San Mateo, and Antipolo.

A fault near Lubang Island in Occidental Mindoro, capable of generating earthquakes felt in Metro Manila.
