The volcano was so strong that it created a huge crater now known as lake Pinatubo as it filled up with water. and (4) Mount Pinatubo (April 1991). 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. Those who didn't return home had to migrate to Manila. All rights reserved. It was the second largest modern eruption after the 1883 Mount Krakatoa eruption in Indonesia.
