Reconstructing the Philippine Sea
For the last 55 million years East Asia has been undergoing a lot of complicated tectonic changes. A new model using the latest geological data has reconstructed the plate movements for that period and has been published in the AGU journal Geophysical Research Letters. The model shows a smooth movement of the Philippine Sea Plate northwards from the equator to its present position, while it rotated clockwise. The model also suggests that a dense slab of the Earth that has been detected beneath the crust of the South China Sea is likely the leading edge of Pacific Plate that was once being forced below by collision and subduction.
