Caption: April 10, 1980 aerial view of Mount St. Helens from the west, showing one of several small steam and ash eruptions that occurred during the day. This eruption occurred about two weeks after the initial eruption on March 27, 1980 at this Cascade Mountain Range volcano and five weeks before the major eruption on May 18, 1980. USGS scientists have estimated that a minimum of one cubic kilometer (1.3 billion cubic yards) of ash and rock was ejected by the volcano during that Sunday morning eruption. In comparison, Mt. Vesuvius produced slightly more than one cubic kilometer in its eruption that buried Pompeii in 79 A.D. The eruption of Indonesia's Krakataua in 1883 produced about 20 cubic kilometers of ash....

Caption: Mount St. Helens sends ash plume two miles high. March 28, 1980 aerial view of Mount St. Helens showing ash and steam eruption that sent volcanic material almost two miles above the mountain's 9,677-foot peak. When the main eruption violently occurred seven weeks later on May 18, 1980, an estimated minimum of 1 cubic kilometer (1.3 billion cubic yards) of ash and rock was ejected by the volcano, according to USGS scientists. In comparison, Mt. Vesuvius spewed slightly more than 1 cubic kilometer in its eruption in 79 A.D. that buried Pompeii. The eruption of Indonesia's Krakataua in 1883 produced over 20 cubic kilometers. The force of the volcanic blast on that Sunday morning in May 1980, was estimated...
