Plate Tectonics

Here is an image of the plate tectonics in the world , my country is in the right side the little green Philippine plate. 

In this picture the diagrams help show what boundaries are near the plate in the country. You mostly see blue which is the subduction zone and there is the divergent, convergent and transform boundaries which altogether make up the same amount of space around , as much as the suduction zone takes up by itself. The movement of the plate is about 80mm a year, and is in motion today increasing the likelihood of earthquakes and tsunamis. The thickness of the plate is about 29-41 km around the Nankai trough. 











                                                             The Philippine Sea plate originated lower than the equator about 55 million years ago and was followed by several tectonic events resulting in its present day location, it was a change in the movement, to a westward motion, of the Pacific plate that has converted the N-S transform fault on the Philippine Sea plate to the subduction zone currently present along the boundary between these two plates.
