MANILA (Reuters) -Evacuations were under way in the Philippines after a quake of at least magnitude 7.5 struck the southern region of Mindanao on Saturday night, triggering tsunami warnings in the ...
MANILA, Philippines (AP) — A powerful undersea earthquake shook the southern Philippines on Friday, causing ceilings in shopping malls to plunge to the ground as shoppers screamed. No tsunami ...
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).
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.
The Marikina Valley fault system, also known as the Valley fault system (VFS), is a dominantly right-lateral strike-slip fault system in Luzon, Philippines. [2] It extends from Doña Remedios Trinidad, Bulacan in the north, running through the provinces of Rizal, the Metro Manila cities of Quezon, Marikina, Pasig, Taguig and Muntinlupa, and the provinces of Cavite and Laguna, before ending in ...

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 ...
The 2019 Luzon earthquake (M w 6.1) and all large earthquakes (M w ≥ 7.0) in Central Luzon. These were in 1968 (Casiguran), 1970, [18] 1977 (in Cagayan Valley), [19] 1985, [20] 1990, and 1999. Geologically, to the left is the Manila Trench and the Iba Fault in Zambales. In the center is the Digdig Fault in Nueva Ecija.
