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 ...
One of the largest historical earthquake on the fault zone was the 1990 Luzon M s 7.8 event that left nearly 2,000 people dead or missing. The same part of the fault zone is thought to have ruptured in the 1645 Luzon earthquake. [7] Further south the fault ruptured during the 1973 Ragay Gulf earthquake.
The largest (M7.0) and most destructive earthquakes are generated along the Guinayangan fault every 30–100 years with slip rates of 20–33 mm/year as determined by GPS and historical records. Moderate earthquakes (M3.0–5.0) are observed along the Masbate fault with frequent aftershocks indicative of continued displacement and regional slip ...
PHIVOLCS Observatory at Mount Hibok-Hibok.. The Philippine Institute of Volcanology and Seismology (PHIVOLCS, Tagalog:; Tagalog: Surian ng Pilipinas sa Bulkanolohiya at Sismolohiya [2]) is a Philippine national institution dedicated to provide information on the activities of volcanoes, earthquakes, and tsunamis, as well as other specialized information and services primarily for the ...

The earthquakes this week were located slightly north of the Ortigalita fault, in an area without any mapped fault lines at the surface. Which parts of Stanislaus County are most at risk for ...
On the West Coast, it can be possible to determine exactly which fault line a quake originated along, the USGS said, because of how well-studied some of those plate boundaries are.
PHIVOLCS initially suspected the earthquake may have occurred on the Abra River Fault. Geologists had been aware of the potential for large earthquakes on the fault. The last known earthquake on the fault was in 1868, measuring 4.0–5.0 in magnitude. [11] The Abra River Fault is a northern extension of the Philippine Fault Zone.
