Why does the Philippines frequently have earthquakes and volcanic eruptions?

Because Philippines is in located in the earth's surface where areas are broken into seven large and many small moving plates. These plates move relative to one another an average of a few centimeters per year. The Philippine Plate is squeezed in between the Eurasian plate and the Pacific Plate, but the situation is more complex than that. The Philippine Islands are surrounded by complex plate boundaries, and the Philippines Plate rather consists of several micro-plates - squeezed in between two convergent plate margins.Because the Philippines is part of the "Ring of Fire". The Pacific Ring of Fire (or sometimes just the Ring of Fire) is an area where large numbers of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 40,000 km (25,000 mi) horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements. The Ring of Fire has 452 volcanoes and is home to over 75% of the world's active and dormant volcanoes. It is sometimes called the circum-Pacific belt or the circum-Pacific seismic belt. A place where Philippines is located.
