 david alexander johnston (december 18, 1949 â may 18, 1980) was an american usgs volcanologist who died during the 1980 eruption of mount st. helens in washington. a principal scientist on the monitoring team, johnston perished while manning an observation post 6 miles () away on the morning of may 18, 1980. he was the first to report the eruption, transmitting "vancouver! vancouver! this is it!" before he was swept away by a lateral blast. johnston's remains were never found, but state highway workers discovered remnants of his usgs trailer in 1993. johnston's career took him across the united states, where he studied augustine volcano in alaska, the san juan volcanic field in colorado, and long-extinct volcanoes in michigan. johnston was a meticulous and talented scientist, known for his analyses of volcanic gases and their relationship to eruptions. this, along with his enthusiasm and positive attitude, made him liked and respected by many co-workers. after his death, other scientists lauded his character, both verbally and in dedications and letters. johnston felt scientists must do what is necessary, including taking risks, to help protect the public from natural disasters. his work, and that of fellow usgs scientists convinced authorities to close mount st. helens to the public before the 1980 eruption. they maintained the closure despite heavy pressure to re-open the area; their work saved thousands of lives. his story became intertwined within the popular image of volcanic eruptions and their threat to society, and a part of volcanology's history. to date, johnston, along with harry glicken, is one of two american volcanologists known to have died in volcanic eruptions. following his death, johnston was commemorated in several ways, including a memorial fund established in his name at the university of washington to fund graduate-level research. two volcano observatories were established and named after him: one in vancouver, washington, and another on the ridge where he
