The San Andreas Fault in California transform boundary.

Studies have shown that the Philippine Sea plate has undergone multiple rotation events in its history, as evidenced from paleomagnetic data (Figure They suggested that the Philippine Sea plate underwent a clockwise rotation of 50 degrees 40-50 Ma, followed by a period of no rotation until 25 Ma when another 40 degree clockwise rotation began, initiating the left-lateral Sorong Fault due to the collision of the Australian plate with the Philippine Sea plate
Figure 3. Various stages of rotation of the Philippine Sea plate according to itial rotation began around 50 Ma. The plate experienced, no rotation between 40-25 Ma. The plate has been rotating again around 25 Ma.

In the northern region of the Philippine Sea plate, part of the Eurasian plate is being subducted beneath the Philippine Sea plate (Figure 4). This is surprising because the Eurasian plate is mostly continental crust, which is typically more buoyant than oceanic crust. However, the subduction is enabled by the South China sea floor, at the southern edge of the Eurasian plate, being more dense and moving at a faster rate than the Philippine Sea plate This drags the Eurasian plate underneath the Philippine Sea plate, creating a unique subduction zone suggesting the presence of a tear in the northern region of the Philippine Sea plate. The variations in stress along the boundary may be linked to the growth of this tear which can be seen in Figure 5 However, to the east of this, around northern Taiwan, the Philippine Sea plate is subducting beneath the Eurasian plate making this region considerably the most active collisional orogen in the world for ocean-continent interactions. Large earthquakes (Mw8.1) have occurred along the Nankai trench in 1944 and 1946 as well as several others due to the subduction of the Philippine Sea plate along its boundaries
