Ancestral Mount Pinatubo was an andesite-dacite stratovolcano for which we have no evidence of large explosive eruptions. The total volume of material erupted may have been up to 25 cubic kilometers (6 mile³), and the removal of this amount of material from the underlying magma chamber led to the formation of a large caldera . Three successive evacuation zones were defined, the innermost containing everything within 10 km (6.2 mi) of the volcano's summit, the second extending 10–20 km (6.2–12.4 mi) from the summit, and the third extending from 20–40 km (12–25 mi) from the summit (Clark Air Base and Angeles were in this zone). After three hours of quiet, seismic activity began, growing more and more intense over the next twenty-four hours, until a three-minute eruptive blast generated a 21 km (13 mi) high eruption column at 13:09 on June 14. Earthquakes and steam explosions announced the reawakening of Mount Pinatubo in 1991, surprising many geologists because Pinatubo was not even listed in catalogs of world volcanoes.
