estimated that there are 1,500 potentially active volcanoes around the world, eruption of Mount Vesuvivus occurred sometime in the autumn of 79 CE, second largest volcanic eruption of the 20, Philippine Institute of Volcanology and Seismology (PHIVOLCS) had been closely monitoring Mount Pinatubo and saved thousands of people, Mount Pinatubo’s eruption caused $700 million in damage, lava domes began forming 20 years after the Santa María volcano erupted, produced 10 cubic kilometers (2.4 cubic miles) of material, another devastating eruption happened in 1929 and also resulted in about 5,000 deaths, Wikimedia Commons via Katmai National Park and Preserve, turned into 30 cubic kilometers (7.2 cu mi) of ash, Huaynaputina ejected 30 cubic kilometer (7.2 cubic miles) of magma, about 1,500 people in the nearby areas died, produced an estimated 45 cubic kilometers (11 cubic miles) of debris, Krakatoa had been dormant for more than 200 years, Wikimedia Commons via ISS Crew Earth Observations by NASA Expedition 20 Crew, 160 cubic kilometers (38 cubic miles) of magma and ash, more than 10,000 people died during the eruptions, Wikimedia Commons via Ed Austin and Herb Jones, volcanic eruption at Yellowstone National Park, ejected between 2,500 – 3,000 cubic kilometers (600 – 719.7 cubic miles), According to some researchers the Toba volcano eruption was so massive that it led to a decade-long volcanic winter, 10 Largest Employers in the United States. Mount Toba eruption (74,000 years ago), Sumatra, La Garita Caldera eruption (~28 million years ago), Colorado, 5 Different Ways of Classifying Volcanoes, Composite Volcano (Stratovolcano): Key Facts and Formation, The Mount Pinatubo Eruption in the Philippines, Mount Tambora Was the Largest Volcanic Eruption of 19th Century. (That’s about 2,500 times more ash than Mount St. Helens erupted!) While Novarupta produced such a large eruption, thankfully there were no deaths. This may have caused a large loss of various species and lowered the Earth’s temperature for the next thousand years. This volcanic eruption created the Yellowstone Caldera, a giant crater that is 1,500 square miles (3,885 square kilometers). This particular eruption was the largest in all of Europe in the past 240 years. That eruption was the biggest since 1912 – a 6 on the Volcanic Explosivity Index. Taking place on 10 April 1815, the eruption was so loud it sounded like a a gunshot to people on the island of Sumatra, 2,600 km (1,615 mi away). The eruption of Mount Pinatubo in 1991 is considered the second largest volcanic eruption of the 20th century, just after Novarupta in 1912. After showing signs of life in 1812, the volcano erupted with such force in 1815 that its 13,000-plus feet peak was reduced to around 9,350 ft. The resulting pumice and ash layer created by Huaynaputina was also quite large and covers an area of 360,000 square kilometers (138,997 square miles). Large volcanic eruptions are more frequent than asteroid impacts of similar magnitude. Yellowstone’s 640,000 year-old volcanic eruption also left behind thick volcanic deposits which are now known as the Lava Creek Tuff. All of the nearby small islands were affected and about 165 coastal villages were destroyed by the tsunami. The tsunami was also massive and was nearly 120 feet (36.58 meters) high. Taal Volcano Eruption in the Philippines is Looking Bad, with Worse to Come. The Santa María volcanic eruption of 1902 produced one of the world’s most active lava dome complexes, which is called Santiaguito. Mount Tambora’s eruption had devastating effects and it is estimated that more than 10,000 people died during the eruptions. The biggest eruption was at Yellowstone about 2.2 million years ago. Tens of thousands of people have died from these volcanic eruptions and their aftereffects. The Mount Pinatubo eruption was the second largest volcanic eruption of the 20th century. The eruption of Krakatoa in 1883 is one of the best-known volcanic eruptions from history for how devastating it was. The eruption of Lake Toba was the biggest volcanic eruption in the Quaternary … Additionally, the Santa María eruption killed more than 5,000 people and destroyed that year’s crops. Volcanoes have helped shape our planet. Source: Wikimedia Commons via Morn the Gorn.
