Mount Pinatubo and the other volcanoes on this volcanic belt arise due to magmatic occlusion from this subduction plate boundary. [ 16 ] Pinatubo is flanked on the west by the Zambales Ophiolite Complex, which is an easterly-dipping section of Eocene oceanic crust uplifted during the late Oligocene .
The 1991 eruption of Mount Pinatubo in the Philippines' Luzon Volcanic Arc was the second-largest volcanic eruption of the 20th century, behind only the 1912 eruption of Novarupta in Alaska. Eruptive activity began on April 2 as a series of phreatic explosions from a fissure that opened on the north side of Mount Pinatubo .
There are 100 volcanoes in the Philippines listed by the Smithsonian Institution's Global Volcanism Program (GVP) at present, [6] of which 20 are categorized as "historical" and 59 as "Holocene". [6] The GVP lists volcanoes with historical, Holocene eruptions, or possibly older if strong signs of volcanism are still evident through thermal ...
A 7.8 M w earthquake strikes the island of Luzon, Philippines. The epicenter was near the town of Rizal, Nueva Ecija, roughly 60 kilometers (37 mi) from Mount Pinatubo. This earthquake caused a landslide, some local tremors, and a brief increase in steam emissions from a preexisting geothermal area at Mount Pinatubo. [2] March–June 1991

Lahars caused most of the deaths of the 1991 eruption of Mount Pinatubo. The initial eruption killed six people, but the lahars killed more than 1500. The eye of Typhoon Yunya passed over the volcano during its eruption on 15 June 1991, and the resulting rain triggered the flow of volcanic ash, boulders, and water down rivers surrounding the ...
