The most recent large-scale event originating from the Manila Trench was the 2006 Pingtung dual earthquakes. These 7.0 earthquakes had 8 minutes of offset and produced a 40-centimetre tsunami; which happened to be the largest tsunami experienced on the southwest Taiwan coast.
In the South China Sea lies the Manila Trench, which is capable of producing M w 9.0 or larger earthquakes, [17] with the maximum magnitude at Mw 9.2 or higher. [ 18 ] In Japan, the Nankai megathrust under the Nankai Trough is responsible for Nankai megathrust earthquakes and associated tsunamis. [ 19 ]
The main hazard comes from shallow fault sources, such as the Marikina Valley Fault System, but there is an important contribution to the overall hazard from the Manila subduction zone to the west and the potential for strong shaking from earthquakes originating the Philippines Trench to the east.

Damaged building as a result of the 1999 Luzon Earthquake. The earthquake resulted in at least 6 deaths and 40 injuries within the regions of Zambales, Pangasinan, and Manila. Of the 40 injuries, 30 were reported in the provinces of Zambales and Pangasinan, while the other 10 were from the Manila metropolitan area. [5]
[3] [2] Subduction results in deep oceanic trenches, such as the Philippine Trench and Manila Trench, which bound the eastern and western sides of the Philippine archipelago, respectively. [4] The Philippine archipelago is also cut along its length by a left-lateral strike-slip fault known as the Philippine Fault. [5] [1]

These two tectonic features thus correlate to a similar time of development. The formation of the PFZ was a result of two stages. The first stage began at ~10 Ma, when the northern segments of the PFZ developed due to the convergence of the China Sea Crust underneath the nearby Manila Trench. The lack of accretionary prism at the Philippine ...
