The focal mechanism and depth corresponded to an earthquake of reverse-faulting at an intermediate depth. [5] On the PHIVOLCS earthquake intensity scale (PEIS), intensity VII (Destructive) was instrumentally recorded in Glan, Sarangani. [2] Intensity VI was reported in General Santos as well as in Polomolok and Koronadal, South Cotabato. [2]
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 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 ...
The quake was at a depth of 10 km (6.21 miles), GFZ said. The U.S. Geological Survey said pegged the magnitude at 6.8. The U.S. National Tsunami Warning Center said that there was no tsunami ...
