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 .

The 1991 Ultra-Plinian eruption of Mount Pinatubo was the second largest terrestrial eruption of the 20th century (surpassed only by the 1912 eruption of Novarupta), and the largest eruption in living memory. The eruption produced high-speed pyroclastic flows, giant lahars, and a cloud of volcanic ash hundreds of miles across. [2]

English: View to the west from Clark Air Base of the major eruption of Pinatubo on June 15, 1991. The June 15-16 climatic phase lasted more than fifteen hours, sent tephra 30-40 km into the atmosphere, generated voluminous pyroclastic flows, and left a caldera in the former summit region.
The eruption is believed to have contributed to the accumulation of atmospheric ash, [citation needed] capped by the catastrophic eruption of Mount Tambora in 1815, that led to the Year Without a Summer in 1816. Pinatubo eruption: 1500 to 2021: Reawakened in 1991 producing the 2nd largest eruption in the 20th century.
The 1991 eruption of Mount Pinatubo, the largest eruption since 1912, is dwarfed by the eruptions in this list. In a volcanic eruption, lava, volcanic bombs, ash, and various gases are expelled from a volcanic vent and fissure. While many eruptions only pose dangers to the immediately surrounding area, Earth's largest eruptions can have a major ...
