The February 5, 2016 M 6.4 earthquake east of Tainan in southern Taiwan occurred as the result of oblique thrust faulting at shallow-mid crustal depths (~ 20 km). Focal mechanisms indicate rupture occurred on a fault oriented either northwest-southeast, and dipping shallowly to the northeast, or on a north-south striking structure dipping steeply to the west. Taiwan lies in a region of complex tectonics, at the boundary between the Philippine Sea and Eurasia plates.
