Some active faults in the Philippines include the Philippine Fault, Manila Trench, and Cotabato Trench. The Manila Trench is a subduction zone where the Philippine Sea Plate slides beneath the Philippine Plate, while the Cotabato Trench is another subduction zone in the southern Philippines. These geological features make the Philippines prone to earthquakes and tsunamis.
Trenches are deep depressions on the ocean floor where one tectonic plate is being forced underneath another. Faults are fractures in the Earth's crust where movement has occurred, resulting in displacement of rock layers. Trenches are associated with convergent plate boundaries, while faults are common at various types of plate boundaries and within the continental crust.
Most geologist consider a particular fault to be an active fault if it has moved during the past 10,000 years of the Holocene Epoch. An inactive fault is one that hasn't moved during the past 10,000 years of the Holocene Epoch.
No, they are not safe. No active creep, that is acting over hundreds of years slowly deforms the crustal rock on both sides of the fault. Ultimately, it leads to the elastic rebound of the rock, that causes big scale earthquakes.
One structure you would find at an active continental margin that you would not find at a passive margin is a subduction zone. Subduction zones occur at active margins where tectonic plates collide, resulting in one plate being forced beneath the other. This process can lead to the formation of volcanic arcs, deep ocean trenches, and earthquakes.
Active faults can generate earthquakes and represent sources of seismic energy. Inactive faults can no longer generate earthquakes but did so in the past. +++ They can, but really the earthquake is the effect of the movement on the fault, so not the defining mechanism. ' An active fault is one still moving (albeit usually in small, irregular steps over millions of years); an inactive fault is stable. If a new phase of tectonic stresses arrive, an inactive fault can be 're-activated', in many cases with the movement in the opposite direction. A fault is a fracture with displacement, and that movement is of the rock on one side of the fault-plane across the other.
