Although there are vast areas of subduction zones, some authors have considered this region to have low seismic activity, [17] though the USGS has recorded many earthquakes with magnitude ≥ 7.2 in the region as shown by the map to the side. Most recently, in 2012 the Philippine Trench experienced an earthquake of M w 7.6 (the 2012 Samar ...
The earthquake occurred as a result of shallow oblique-thrust faulting likely along the subduction interface of the Philippine Trench. At this location, the Philippine Sea plate moves west-northwest at a rate of about 103 mm (4.1 in) per year with respect to the Sunda plate. A finite fault model suggests rupture occurred around an elliptical ...
The subduction zones that surround most of the archipelago are the source of many of the larger earthquakes that strike the Philippines. 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.

Faults and subduction zones are the seismic origins. Among subduction zones in the Philippines, subduction along the Philippine Trench produces the most active and frequent seismic activities to the region. However, as the Philippine Trench is a young subduction system, the majority are shallow earthquakes (less than 30 km [clarification needed ...
The Manila Trench is an oceanic trench in the Pacific Ocean, located west of the islands of Luzon and Mindoro in the Philippines. The trench reaches a depth of about 5,400 metres (17,700 ft), [ 8 ] in contrast with the average depth of the South China Sea of about 1,500 metres (4,900 ft).
At least four people were reported killed after a magnitude 7.0 earthquake impacted 218 towns in 15 provinces in the Philippines, on July 27, according to ABS-CBN News, citing the interior ...
