On June 12, 1991, Mount Pinatubo in the Philippines erupted with tremendous force, announcing the strongest volcanic eruption of the 20th century in terms of power and global impact. This event not only changed the map of the region but also affected the global climate for years.
The Volcano that Awakened after 600 Years
Mount Pinatubo on the island of Luzon in the Philippines had been dormant for approximately 600 years. However, in April 1991, small earthquakes began to strike the area, warning scientists that the volcano had awakened. The Philippine government started evacuating more than 58,000 people from the surrounding area.
The Day of the Disaster: June 12, 1991
In the morning of that day, the volcano erupted with a force that humanity had not seen since the eruption of Novarupta in Alaska in 1912. It launched columns of ash and rocks to a height of 35 kilometers into the sky. This was the moment that history would retain as the second-largest volcanic eruption of the 20th century.
The eruption continued for hours, including three major explosions over several days. This led to the destruction of nearby cities and the coverage of the area with a thick layer of volcanic ash.
Victims and Damage
Despite the successful evacuation, about 847 people lost their lives in the disaster. The eruption destroyed US military installations at a nearby airbase, forcing the United States to leave the Philippines after centuries of military presence there.
Subic Bay, which was an important tourist and maritime area, became a ghost town covered in ash. The Philippine economy suffered losses of approximately $700 million that year.
Global Climatic Impact
The eruption released 20 million tons of sulfur dioxide into the atmosphere, leading to a global temperature drop of about 0.5 degrees Celsius in the following two years. The effects of the volcanic ash remained in the atmosphere for years.
Images of the volcano from space (taken by cosmonauts at the Mir space station) astonished the world, as the volcanic cloud seemed to be wrapped around the Earth.
Lessons in Preparation and Evacuation
The 1991 Pinatubo eruption is considered a model case study in volcanology and disaster management. Scientists successfully predicted the eruption and evacuated thousands of people, teaching the world the importance of proper preparation for natural disasters.
On this day (June 12), we remember how a crack in the Earth in a small mountain in the Philippines changed the global climate and proved that humanity and science together can face the most severe natural disasters.
