Pinatubo injected about 15 million tons of sulfur dioxide into the stratosphere, where it reacted with water to form a hazy layer of aerosol particles composed primarily of sulfuric acid droplets. The disaster impacted approximately two million people directly, primarily by widespread ashfall and damaged crops. . The denser oceanic philippine plate subducted under the less dense continental Eurasian plate. The rainwater mixed with the loose volcanic material on the volcanos slopes to form a dense, viscous mud with the consistency of wet cement and caused mudflows, called lahars, to race down Pinatubos slopes. There, the gas combined with water to create aerosol particles.
