The ash and smoke cloud ejected by Mount Pinatubo in 1991 contained about twice as much matter as that thrown up by the El Chichn volcano (1982), making Pinatubo perhaps the largest eruption of the 20th century. In situ temperature changes and related effects thus provide indirect measures of EEI. These explosions reached a peak on June 1416, producing a column of ash and smoke more than 28 miles (40 km) high, with rock debris falling the same distance from the volcano.
