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 studies of Stenchikov et al. (2009) and Iwi (2012) suggest that both Krakatau and Pinatubo may have strengthened the overturning circulation. And the increase in AMOC seems to be strongest at about one decade after the volcano eruption, with a magnitude of about one sverdrup for Krakatau and Pinatubo. [1] [13]
The eruption column of Mount Pinatubo on June 12, 1991, three days before the climactic eruption 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 about 35 km (22 mi) into the atmosphere, generated voluminous pyroclastic flows ...
1991: Mount Pinatubo, Philippines. On June 15, 1991, a rumbling Mount Pinatubo grew and grew until it exploded in the biggest volcanic eruption on Earth in 100 years. Super-pressurized, gas ...
On June 15, 1991, the island of Luzon in the Philippines was ground zero for the second-largest volcanic eruption of the 1900s when Mount Pinatubo blew its top. This historic natural event set ...
Location of Mount Pinatubo, showing area over which ash from the 1991 eruption fell. Satellite measurements of ash and aerosol emissions from Mount Pinatubo. MLO transmission ratio - Solar radiation reduction due to volcanic eruptions
An eruption as large as Mount Pinatubo in 1991 could certainly cool the planet for a few years, though it wouldn’t be able to erase the Earth’s current climate woes caused by planet-warming ...
The effects of the eruption were felt world-wide. It injected large amounts of aerosols into the stratosphere—more than any eruption since that of Krakatoa in 1883. Global temperatures dropped by about 0.5 °C (0.9 °F), and ozone destruction increased substantially. Recently featured: Blue Whale – Dalek – Stanislaw Koniecpolski
