1. Harry Glicken researched Mount St Helens in the United States before and after its 1980 eruption, and was very distraught about the death of volcanologist David A Johnston, who was Glicken's mentor and supervisor in Spring 1980 at Mount St Helens.
Harry Glicken's remains were found four days later and were cremated in accordance with his parents' request.
Harry Glicken wrote several major publications on the topic, including his doctoral dissertation based on his research at Mount St Helens titled "Rockslide-debris Avalanche of May 18,1980, Mount St Helens Volcano, Washington" that initiated widespread interest in the phenomenon.
Harry Glicken was born in 1958 to Milton and Ida Harry Glicken.
Harry Glicken monitored the volcano for two weeks, taking shelter in a trailer at the Coldwater II site located a little more than 5 miles northwest of the volcano.
On May 18,1980, after working for six days straight, Glicken took the day off to attend an interview for his graduate work with his professor, Richard V Fisher, in Mammoth Lakes, California.
Harry Glicken attempted to enlist a fourth helicopter crew to aid his search, but they declined, fearing dangerous conditions.
Harry Glicken returned to St Helens hoping to join the 'autopsy' team.
However, every aspect of the eruption had been claimed by different survey scientists, and as a doctoral student at UC Santa Barbara studying with Richard Fisher, Harry Glicken was not a survey employee.
Under Voight's guidance, Harry Glicken absorbed himself in his work, motivated to earn a job at the Survey, and to relieve some of his anguish over Johnston's death.
Harry Glicken continued helping the Survey until 1989, serving as an assistant researcher at the University of California at Santa Barbara.
From 1989 to 1991, Harry Glicken continued his volcanological studies in Japan as a postdoctoral fellow at the Earthquake Research Institute of the University of Tokyo, supported by grants from the US National Science Foundation.
Later, while a research professor and translator at Tokyo Metropolitan University, Harry Glicken became involved with research at Mount Unzen.
On June 2,1991, Harry Glicken visited the mountain with Katia and Maurice Krafft.
Harry Glicken's remains were found four days later, and were cremated according to his parents' wishes.
At the time of his death, Harry Glicken had been seeking to publish his doctoral dissertation in one piece, having earlier published elements as shorter articles.
Harry Glicken had already defined the criteria for debris avalanches on the slopes of volcanoes, and authored several publications on the subject; Swanson named him one of the foremost experts in the field.
Harry Glicken's report is titled "Rockslide-debris Avalanche of May 18,1980, Mount St Helens Volcano, Washington".
Chatty, noted for being extremely sensitive, Harry Glicken paid meticulous attention to detail.
Harry Glicken's father said in 1991 that his son died pursuing his passion, and that he was "totally absorbed" with volcanology.
Harry Glicken was closely connected to the University of California, Santa Barbara, where he earned his doctorate and conducted research.
Harry Glicken coauthored works with other volcanologists that focused on debris avalanches.
