The June 12-15, 1991, eruption of 1475m Pinatubo volcano, located 100 kilometers northwest of Manila in the Philippines, was one of the largest eruptions of this century and it strongly effected some aspects of our climate.

In total the Pinatubo eruption discharged 5 billion cubic meters of ash and pyroclastic debris (including 20 to 30 megatons of sulphur dioxide and aerosols) into the atmosphere via eruption columns which were 18km wide at the base and had heights of up to 30km.
