This includes both faulting along the plate interfaces and within the subducting slabs. For the Philippine Trench, examples of those on the plate interface are the 1988 M w 7.3 and the 2023 M7.6 events. The 1975 M w 7.6 earthquake was caused by intra-slab normal faulting, while the 2012 M7.6 was a result of thrust faulting within the descending ...
An earthquake map of the Philippines from 1862-1909, published in Catalogue of Violent and Destructive Earthquakes in the Philippines With an Appendix: Earthquakes in the Marianas Islands 1599-1909, by Rev. Miguel Saderra Masó, SJ, published in Manila by the Bureau of Printing in 1910.
The earthquakes were originally given estimated magnitudes of 8.6 and 8.7 on the surface-wave magnitude scale by Charles Richter, [1] [2] but these were revised downwards by Katsuyuki Abe to 7.4 and 7.5 M s, respectively. [3] Contemporary reports noted that with few exceptions, all the masonry buildings in Zamboanga and Basilan were left in ...
The world's sixth most powerful earthquake of the year, it registered a magnitude of 7.5 and was a megathrust earthquake. It originated near the Cotabato Trench , a zone of deformation situated between the Philippine Sea plate and the Sunda plate , and occurred very near to the Philippines' strongest earthquake for the 20th century, the 1918 ...
The earthquake causing this event has been predicted to be of magnitude 9.35 (stronger than the 9.1–9.3 magnitude 2004 Sumatra event). This massive earthquake, which would be the 2nd strongest in recent history, would have a total length of 990 km and a maximum wave height of 9.3 metres.

The earthquake struck at 8:18 PM [4] and had a surface wave magnitude of 6.5. [3] It was the most powerful earthquake to strike the Philippines in seven years. Shaking lasted 20 seconds and damaged seven towns extensively, [4] its greatest damage occurring near Pasuquin, Laoag, Sarrat, and Batac in the Ilocos Norte province.
The 2010 Mindanao earthquakes occurred in the southern Philippines in the Moro Gulf.This was a complex sequence of events including three main events (a triplet earthquake) of M w magnitude 7.3 or greater on the 23rd of July, and two significant aftershocks of magnitude 6.6 on the 24th and 29th.
