After the eruption, Voight accepted a position as a consultant for the USGS. He led the investigation into the volcano debris avalanche which had occurred during the eruption, guiding other volcanologists including Harry Glicken, who built upon Voight's preliminary research to create his report Rockslide-Debris Avalanche of May 18, 1980, Mount St. Helens Volcano, Washington (1996). Voight's work won him international renown, and he later cited his experiences there as career-changing. Although Voight already had a burgeoning interest in volcanology, the eruption at Mount St. Helens propelled him to dedicate himself to the field. His work helped reinvigorate widespread interest in landslides and other phenomena at volcanoes that potentially pose a threat to life. After completing his research at Mount St. Helens, Voight began analyzing the volcanic hazards from several other active volcanoes.
