Caption: Volcanic eruption creates scenes of destruction. Ash, pumice, pieces of wood and other volcanic debris clogged many water bodies near Washington State's Mount St. Helens after the volcano erupted violently on May 18, 1980. According to U.S. Geological Survey scientists, the first eruption of the Cascade Mountain Range volcano in 123 years occured with an atom bomb-like force that leveled trees in a 185 square mile area and spewed over 1 cubic kilometer of ash and rock over 11 western and central states. PIO No. 80-180b

Caption: Scientists studying hydrologic effects of Mount St. Helens eruption. Hydrologic analysdis including water flow rate, chemical composition, and temperature are shown being made by U.S. Geological Survey scientists near Washington state's Mount St. Helens volcano. The first eruption of the Cascade Mountain Range volcano in 123 years caused flooding and pollution of the waterways near the mountain. Studies such as these provide data that will help in preparations for future volcanic eruptions throughout the U.S. and other countries. According to the USGS, over 1 cubic kilometer of ash and rock were ejectd by the volcano during its main eruption on May 18, 1980. Measureable amounts of volcanic material were...

Caption: Mount St. Helens spews steam and ash. April 12, aerial view of Mount St. Helens from the south, showing one of several steam and ash eruptions that occurred during the day. This eruption occurred about two weeks after the initial eruption on March 27 at this Cascade Mountain Range volcano and about five weeks before the major eruption on May 18. 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. Vesivius produced slightly more than one cubic kilometer in its eruption that buried Pompei in 79 A.D. The eruption of Indonesia's Krakatoa in 1883 produced about 20 cubic...

Caption: One group of USGS scientists is being met by another scientist on May 2, 1980 waiting to leave by helicopter to make further studies of Mount St. Helens before the main eruption of May 18, 1980. Aerial observations and photographs as well as instrument readings are the primary tools used by the USGS in studying the Cascade Mountain Range volcano in Washington state. According to the USGS, the vast amounts of data collected from the eruption, one of the most highly studied events of its kind, will be useful in improving not only the understanding of volcano dymanmics but also the predictive capabilities for future eruptions. Note: David A. Johnston, USGS volcanologist, facing helicopter. PIO No.: 80-147b...

Caption: Scientists fly to Mount St. Helens area to survey volcano damage. The explosive force of the Washington state's Mount St. Helens eruption can be seen in this photo taken near the volcano shortly after its first eruption in 123 years. In an atom bomb like blast, which removed over 5,000 feet of the north face of the mountain, the volcano spewed ash and debris over 11 western and central states. Because of the rugged terrain and the dangers involved in being near the mountain, many USGS scientitst used helicopters, which provided the means for a quick evacuation, to study the effects of the eruption. Over 185 square miles of forestland were flattened by the May 18, 1980 eruption. PIO No. 80-237

Caption: Mount St. Helens volcanic drama continues. Three years have gone by since Mount St. Helens blew its snow-covered peak on May 18, 1980. in an eruption which U.S. Geological Survey scientists characterize as the most violent olcanic event in the continental United States during the 20th century. The drama of the reawakened volcano continues, but in a lower key as evidenced in this recent photo of the crater of Mount St. Helens, taken from Harry's Ridge, five miles to the north. Here the new dome may be seen arising from the crater-- the result of an accumulation of lavga spewed duirng repeated volcanic eruptions. The eastern side of the dome has been growing slowly since early March, accompanied by low-leel...

Caption: Mount St. Hlens knocks down trees, spawns massive mud flows. June 4, 1980 aerial view of large mudflow on Washington state's Toutle River caused by the May 18, 1980 eruption of Mount St. Helens. The volcano erupted violently after 124 years of dormancy and knocked down trees in a heavily forested 185-square-mile area and caused mudflows up to several hundred feet thick. EROS no. 80-S5-146. PIO no. 80-S5-146.

Caption: A U.S. Geological Survey bronze plaque was dedicated in recent ceremonies at USGS Western Region Headquarters, Menlo Park, California, to honor the memory of Dr. David S. Johnston, 30-year old volcanologist, who died while manning his observation post during the violent May 18, 1980 eruption of the Mt. St. Helens volcano in Vancouver, Washington. USGS chief geologist, Dallas Peck, of the National Center, Reston, Virginia, joined colleagues and friends in presiding over the Western Center ceremonies. A pistachio treealso was planted adjacent to the plaque. PIO No. 80-235
Caption: Mount St. Helens emits steam and ash. April 10, 1980 aerial view of Mount St. Helens from the northeast, 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.

Caption: Mount St. Helens forms two craters. March 31 aerial view of ash-laden Mount St. Helens from the northwest showing the two craters formed after the initial eruption on March 27. The craters measure approximately 300' x 450' and 90' x 150' and were contained in the original summit crater prior to the largest eruption on May 18. Unlike the relatively mild earlier eruption, the May 18 event was violent and destructive. Over 5,000 feet of the upper north flank of the mountain was opened up by the force of the explosion, which was termed comparable to the energy output of 10-50 megatons of TNT-- about 500-2,500 times more powerful than the atomic blast at Hiroshima at the end of WWII. The ash and rock ejected...
