The 1991 Mount Pinatubo Eruption: A Cataclysmic Event

Mount Pinatubo, a stratovolcano in the Zambales Mountains of Central Luzon, Philippines, erupted on June 15, 1991, in what is widely regarded as the second-largest volcanic eruption of the 20th century, surpassed only by the 1912 Novarupta eruption in Alaska. Rated as an Ultra-Plinian eruption with a Volcanic Explosivity Index (VEI) of 6, it ejected approximately 10 cubic kilometers of material and had profound local and global impacts. The eruption's significance lies in its devastating effects on local communities, its role in advancing volcanology through successful monitoring, and its influence on global climate.
