Long-form answers:
knowledge: content: Mount Pinatubo (Sambal: Bakil nin Pinatobo; Kapampangan: Bunduk/Bulkan ning Pinatubu, Bunduk ning Apu Malyari; Pangasinan: Palandey/Bulkan na Pinatubu; Ilocano: Bantay Pinatubo; Tagalog: Bundok/Bulkang Pinatubo IPA: [pinɐtubɔ]) is an active stratovolcano in the Zambales Mountains, located on the tripoint boundary of the Philippine provinces of Zambales, Tarlac and Pampanga, all in Central Luzon on the northern island of Luzon.[4][5] Its eruptive history was unknown to most before the pre-eruption volcanic activity of early 1991.

content: c. 33,000 BC: After a long period of dormancy, Modern Pinatubo was born in Ancestral Pinatubo's cataclysmic and most explosive eruptions, estimated to be five times larger than the June 1991 eruption.

content: c. 7000 BC (Pasbul Eruptive Period). Its eruptions were as energetic, if not as voluminous as the Inararo eruptions.
wikipage: Mount Pinatubo Modern Pinatubo
content: c. 4000–3000 BC (Crow Valley Eruptive Period). This and the Mara-unot period's eruptions were smaller than the Inararo eruptions but about two to three times as big as that of 1991 based on the pyroclastic flow runout distances and depths of valley filling.

content: c. AD 1500 (Buag Eruptive Period). Its eruptions were roughly the same size as those of 1991.

content: In March and April 1991, magma rising toward the surface from more than 32 km (20 mi) beneath Pinatubo triggered small volcano tectonic earthquakes and caused powerful steam explosions that blasted three craters on the north flank of the volcano.
