For recent Philippine earthquakes, a third of the largest ones (M ≥ 6.3) since 2001 have been near the Cotabato Trench.
The Cotabato Trench is an oceanic trench in the Pacific Ocean, off the southwestern coast of Mindanao in the Philippines. Along this trench the oceanic crust of the Sunda Plate beneath the Celebes Sea is being subducted beneath the Philippines Mobile Belt. It forms part of a linked
set of trenches along the western side of the Philippines formed over east-dipping subduction zones, including the Manila Trench and the Negros Trench.[1] At its northern end the rate of convergence across this boundary is about 100 mm per year.[2] It is a relatively young structure, forming during the late Miocene to Pliocene.[3] This age is consistent with the estimated age of the sedimentary rocks in the accretionary wedge associated with the trench and the age of adakitic arc rocks on Mindanao thought to date the onset of subduction.[4]
