What is the subduction zone of mt Pinatubo?

The subduction zone of Mount Pinatubo is located where the Philippine Sea Plate is being subducted beneath the Eurasian Plate. This geological process contributes to the volcanic activity of Mount Pinatubo, which is part of the Zambales mountain range in the Philippines. The interaction between these tectonic plates leads to the formation of magma, resulting in explosive eruptions, such as the significant eruption that occurred in 1991. This subduction zone is a key factor in the region's volcanism and seismic activity.
