Precursor activity
Since its last eruptive activity in 1857, Mount St. Helens had been largely dormant. Seismographs were not installed until 1972. This period of 123 years of inactivity ended in early 1980. On March 15, a cluster of tiny earthquakes rocked the area around the mountain. For six days, more than 100 earthquakes clustered around Mount St. Helens, an indication that magma was moving. There was initially some doubt as to whether the earthquakes were precursors to an eruption. By March 20, a magnitud...
Final signs and primary blast
Given the increasing seismic and volcanic activity, Johnston and the other volcanologists working for the USGS in its Vancouver branch prepared to observe any impending eruption. Geologist Don Swanson and others placed reflectors on and around the growing domes, and established the Coldwater I WikiMiniAtlas46°17′55.8″N 122°17′22.9″W / 46.298833°N 122.289694°W / 46.298833; -122.289694 and II WikiMiniAtlas46°16′37.5″N 122°13′28.0″W / 46.277083°N 122.224444°W / 46.277083; -122.224444 obser...
USGS team and rescue efforts
Many USGS scientists worked on the team monitoring the volcano, but it was graduate student Harry Glicken who had been manning the Coldwater II observation post for the two and a half weeks immediately preceding the eruption. The evening before the eruption he was scheduled to be relieved by USGS geologist Don Swanson, but something came up, and Swanson asked Johnston to take his place. Johnston agreed. That Saturday, the day before the eruption took place, Johnston ascended the mountain and...
Scientific
Johnston was commemorated by both his fellow scientists and by the government. Known for his diligent and particular nature, he was called "an exemplary scientist" by a USGS dedication paper, which also described him as "unaffectedly genuine, with an infectious curiosity and enthusiasm". He was quick to "dissipate cynicism" and believed that "careful evaluation and interpretation" was the best approach to his work. An obituary notice for Johnston stated that at the time of his death he had be...
Commemoration
Early acts of commemoration included two trees that were planted in Tel Aviv, Israel,and the renaming of a community center in Johnston's hometown as the "Johnston Center". These actions were reported in newspapers during the first anniversary of the eruption in May 1981. On the second anniversary of the eruption, the USGS office in Vancouver (which had been permanently established following the 1980 eruption) was renamed the David A. Johnston Cascades Volcano Observatory (CVO) in his memory....
Depictions
There have been several tellings of Johnston's story in documentaries, films and docudramasabout the eruption. In the 1981 HBO television film St. Helens, actor David Huffman starred as David Jackson, a fictional character supposedly based on Johnston, but with almost no representation of his actions in 1980. Johnston's parents objected to the production of the film, arguing that it possessed not "an ounce of David in it" and portrayed "him as a daredevil rather than a careful scientist". Joh...
