Volcano Shape

Mt. Pinatubo is located at 15.13N, 120.35E.
Its elevation is 5248 ft (1600 m)

The birth of now-a-days Pinatubo occurred in the most explosive eruption in its history, which deposited pyroclastic flow material up to 100 meters thick on all sides of the mountain. The total volume of material erupted may have been up to 25 cubic kilometers , and the removal of this amount of material from the underlying magma chamber led to the formation of a large caldera.  Pinatubo is a stratovolcano,which are also called composite volcanoes. They are tall, conical volcanos with many layers of hardened lava and volcanic ash. Stratovolcanoes have steep profiles and periodic, explosive eruptions. The lava that flows from it tends to be viscous; it cools and hardens before spreading far. The magma forming this lava is often felsic, having high-to-intermediate levels of silica , with less amounts of less-viscous mafic magma.  Several mountains near Pinatubo are old satellite vents of olden days Pinatubo, formed from volcanic plugs and lava domes. Some nearby peaks are also remains of old Pinatubo, formed from erosion-resistant parts of the old mountain slopes left behind when the less resistant parts were eroded away by weathering.
