The Philippine Fault Zone which trends n40°w is widely accepted as a major strike-slip fault comparable to the San Andreas fault. An area in south-eastern Luzon, commonly regarded as part of the main fault zone, has been studied in an effort to date the faulting and to establish its nature and extent.
What kind of fault is the Philippines?
Tectonic settings and the two earthquakes in 1947 and 2017 along the Philippine fault on Leyte. The Philippine fault is a major left-lateral strike-slip fault that runs through the Philippine archipelago (Fig. 1).
Why Philippines have many faults?
The Philippine Mobile Belt is compressed on the west by the Eurasian Plate and two arms of the Sunda Plate, and on the east by the Philippine Sea Plate. These tectonic plates have compressed and lifted parts of the Philippines causing extensive faulting, primarily on a north–south axis.
Is the Philippines on a fault line?

What will happen if the big one hits the Philippines?
When the Big One comes, the Metropolitan Manila Earthquake Impact Deduction Study (MMEIRS) predict that it will destroy bridges around the metro and damage public buildings. Cut off from other cities, at least 34,000 people are predicted to die and 170,000 residential houses will collapse.
What is the longest fault line in the Philippines?

What is the big one Philippines?
The “Big One” is a worst-case scenario of a 7.2-magnitude earthquake from the West Valley Fault, a 100-kilometer fault that runs through six cities in Metro Manila and nearby provinces. A tsunami is also foreseen in the scenario set by the Philippine Institute of Volcanology and Seismology (PHIVOLCS).
What is the longest mountain in the Philippines?

What is the most dangerous fault line?
Wasatch Fault Zone
As with most fault zones, this one has several distinct segments and each has its own history of quakes. On average, every 300 to 350 years, one of the central segments has had a major earthquake. The last large rupture was 300 years ago and seismologists think the system is long overdue for another.
How far from fault line is safe?
But first, what is considered a safe distance from a fault line? PhiVolcs recommends avoiding construction within five meters on each side of a fault trace. This is equivalent to a total width of 10 meters. This is considered the ideal “10-meter wide no-build zone” in the vicinity of a fault.
