| June 15, 1991 :The Pinatubo Big Bang! by Stephanie Pappas, Live Science Contributor. |
In the middle of the day on June 15, 1991, the largest land volcano eruption in living history shook the Philippines island of Luzon as Mount Pinatubo, a formerly unassuming lump of jungle-covered slopes, blew its top. Ash fell as far away as Singapore, and in the year to follow, volcanic particles in the atmosphere would lower global temperatures by an average of 0.9 degrees Fahrenheit (0.5 degrees Celsius).
Mount Pinatubo’s “big-bang” eruption coincided with a tropical storm, which proved to be a fortunate thing for the people of Central Luzon, as the thousands of tons of volcanic debris was spread out throughout the island of Luzon and reached as far as Visayas and Mindanao. Ashfall was even reported in Hong Kong and other nearby foreign territories.

The volcano, located along the boundaries of Pampanga, Tarlac and Zambales provinces, initially exploded in the afternoon of June 12, 1991 when a gigantic mushroom-shaped cloud suddenly appeared above the western sky of Angeles City.
