The ashfalls forced the evacuation and eventual closing of U.S.-leased Clark Air Force Base, 10 miles (16 km) east of the volcano. Those functions are the backbone of CDCs mission. 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.
