This eruption was the largest in at least 1,300 years (after the hypothesized eruption causing the volcanic winter of 536); its effect on the climate may have been exacerbated by the 1814 eruption of Mayon in the Philippines. The significant amount of volcanic ash and gases released into the atmosphere blocked sunlight, leading to global cooling.
The 1991 eruption rated 6 on the Volcanic Explosivity Index and came some 450–500 years after the volcano's last known eruptive activity. The eruption ejected about 10 km 3 (2.4 cu mi) of material, making it the largest eruption of the 20th century since that of Novarupta in 1912 and some ten times larger than the 1980 eruption of Mount St ...
In summer 1816, countries in the Northern Hemisphere suffered extreme weather conditions, dubbed the "Year Without a Summer". Average global temperatures decreased by about 0.4 to 0.7 °C (0.7 to 1.3 °F), [8] enough to cause significant agricultural problems around the globe. On 4 June 1816, frosts were reported in the upper elevations of New ...
The Philippines' Mount Bulusan erupted for 17 minutes Sunday, sending a plume of ash up at least one kilometer, which is about 0.6 miles, into the atmosphere and covering several towns in volcanic ...
Pinatubo is known for its VEI-6 eruption on June 15, 1991, the second-largest terrestrial eruption of the 20th century after the 1912 eruption of Novarupta in Alaska. [7] The eruption coincided with Typhoon Yunya making landfall in the Philippines, which brought a dangerous mix of ash and rain to nearby towns and cities.
The Philippines' Kanlaon volcano erupted for nearly four minutes, shooting ash 2.5 miles into the sky and prompting the emergency evacuation of some 87,000 people. Tens of thousands of people ...
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 ...
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.
