The longest and most seismically active of the strike-slip structures is the 1200 km long Philippine Fault Zone. [6] It carries the left lateral component of the oblique convergence at the Philippine Trench, with a current estimated slip-rate of 35 ± 4 mm per year on Leyte, reducing northwards to about 20 mm per year on Luzon. On Luzon, the ...
At 16:14 PST (08:14 UTC) on November 17, 2023, the province of Sarangani on the island of Mindanao in the Philippines was struck by an earthquake measuring 6.7 M ww.It had a maximum perceived intensity of VIII (Severe) on the Modified Mercalli Intensity Scale.
The earthquake occurred as a result of shallow oblique-thrust faulting likely along the subduction interface of the Philippine Trench. At this location, the Philippine Sea plate moves west-northwest at a rate of about 103 mm (4.1 in) per year with respect to the Sunda plate. A finite fault model suggests rupture occurred around an elliptical ...

The earthquake ruptured approximately 100 km of the Philippine Fault System along the Surigao segment. The Surigao segment strikes in a slightly north-northeast orientation. Left-lateral stream offsets, and 1-meter-high scarps are evident that the fault is active. By studying the surface rupture length, a moment magnitude of 7.4 was estimated. [4]
A magnitude 3.4 earthquake hit the Fontana area Saturday, the U.S. Geological Survey said. The Inland Empire quake was centered just under five miles northwest of Fontana, the agency said.
