Index card: Oblique aerial view of Mount St. Helens in eruption from west, showing upper part of volcano and eruptive plume. 1516 hrs. Skamania County, Washington. May 18, 1980. (Part of plane visible at left).
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...

Caption: Huge crater left by Mount St. Helens eruption. The May 18, 1980, eruption of Mount St. Helens volcano in Washington State produced a crater at the mountain approximately one kilometer wide and two kilometers long. According to U.S. Geological Survey scientists, the atom bomb-like force of the main eruption also exploded out about 5,000 feet of the north face of the mountain and leveled trees in a 185 square mile area. The volcano last erupted 123 years ago. PIO No. 80-179.

Caption: Mount St. Helens levels 185 square miles of forestland. Thousands of trees knocked down by the atom bomb-like blast of the May 18, 1980, eruption of southern Washington state's Mount St. Helens volcano are shown in this photo taken near the mountain several weeks after the main eruption. According to U.S. Geological Survey scientists, the Cascade Mountain Range volcano's first eruption in 123 years leveled trees in a 185 square mile area and spewed about 1 cubic kilometer of ash and rock which fell over 11 western and central states. August 1980. PIO No. 80-180c
