The Philippine Fault Zone (PFZ) extends 1200 km across the Philippine archipelago behind the convergent boundary of the Philippine Trench and the subduction of the Philippine Sea Plate. [3] This left-lateral strike-slip fault extends NW-SE (N30 – 40 W) accommodating the lateral oblique motion of the subducting Philippine Sea Plate with ...
Large-scale digital mapping of the Philippine fault zone based on aerial photograph interpretation . The 1,200-km-long Philippine fault zone (PFZ) is a major tectonic feature that transects the whole Philippine archipelago from northwestern Luzon to southeastern Mindanao. This arc-parallel, left-lateral strike slip fault is divided into several segments and has been the source of large ...
The Philippine Fault is a left-lateral strike-slip fault which cuts across the Philippine archipelago behind the subduction zone. It is a northwest–southeast trending fault, which aligns subparallel to the Philippine Trench, extends from northern Luzon to Mindanao.

The fault systems in the country are mostly oblique strikeslip faults belonging to the Philippine Fault Zone (PFZ) (Fig. 1) (Aurelio, 2000b;Barrier et al., 1991; Tsutsumi and Perez, 2013). The PFZ ...

The Philippine Fault goes through the island of Leyte from its northern to its southern shores, with a marked 150-km-long onshore trace. At the latitude of the island, the fault crosses the volcanic arc associated with the Philippine Trench subduction zone (Barrier et al., 1991) (inset of Figure 1).
Key words: Philippine Fault Zone (PFZ), historical earthquakes, slow events, creep, Masbate fault, transition zone, Guinyangan fault, Leyte fault. 1. Introduction One of the major tectonic features in the Philippine re-gion is the Philippine Fault Zone (PFZ). The PFZ is a left-lateral strike-slip fault that transects the whole archipelago
The central Philippine Fault Zone is found to be the locus of great earthquakes, a transition zone with slow slip and creep activity. This is based on the analysis and correlation of seismic historic data and detailed documentation of recent seismic events in the region. Based on this study the Guinyangan fault is defined to be the northern locked portion with recurrence interval of as short ...

The structure of the district is dominated by a complex zone of N-to NW-trending faults of the Abra River fault system (Fig. 1A), which is the main branch of the Philippine fault running along the ...
The Philippine fault is a ~1250-km-long, left-lateral strike-slip fault extending NNW parallel to the Philippine archipelago. This fault has been very active in the past 200 years with several destructive earthquakes accompanied by surface rupture. However, there was no large-scale map of the Philippine fault, which is essential for mitigating seismic hazard from future earthquakes. We mapped ...

The fault gouge in the core and the damage zone of rock mass of the fault zone constitute an important geological factors in the formation of landslides, and the softening and swelling effect of the fault gouge is obvious under the action of reservoir water fluctuation (Fig. 20f), so this area has experienced several landslides since April 2020 ...
The Philippine Fault is considered a trench-linked strike-slip fault behind a subduction zone-the Philippines Trench, particularly the East Luzon Trough in the North Luzon area, as a consequence ...
The Philippine Fault Zone, which extends for 1,200 km is labeled in this map, as is the Philippine Trench, both of which pose significant seismic hazards to the country. The Philippine Fault Zone is a 1,200 km-long tectonic feature stretching through the entire Philippine archipelago.
The tectonic setting of the Philippines is unusual in several respects: it is characterized by opposite-facing subduction systems on its east and west sides; the archipelago is cut by a major transform fault, the Philippine Fault; and the arc complex itself is marked by active volcanism, faulting, and high seismic activity.

In contrast, the fault in Masbate and Leyte Islands are more continuous and produced only moderate earthquakes in the past 400 years. There are geomorphic and geodetic evidence of aseismic creeping on the Philippine fault in northern and central Leyte. These observations suggest that the Philippine fault may be comparable to the San Andreas ...
