What caused the eruption of Mt. Pinatubo in 1991?

The relatively small Phillipine tectonic plate slowly moving west sliding underneath the larger Indo-Australian plate caused the Mount Pinatubo eruption of 1991. The plate rocks then melted to form magma and made its way to the surface through Mount Pinatubo and the other volcanoes in the famous ring of fire. This is bad news for the people of the Philippines who live on the island of Luzon as due to the nature of the cause of this huge devastating eruption, it looks likely that it will erupt again in the near future. However with careful monitoring, if the volcanic activity of Mt. Pinatubo does begin to rise more than normal no one will be killed or at least the death toll may be kept to the minimum by evacuation etc.
