Harry Glicken
Harry Glicken was an American volcanologist. He researched Mount St. Helens in the United States before and after its famous 1980 eruption, and blamed himself for the death of fellow volcanologist David A. Johnston, who had switched shifts with Glicken so that the latter could attend an interview. In 1991, while conducting avalanche research on Mount Unzen in Japan, Glicken and fellow volcanologists Katia and Maurice Krafft were killed by a pyroclastic flow. His remains were found four days later, and were cremated in accordance with his parents request. Glicken and Johnston remain the only American volcanologists known to have died in volcanic eruptions.
Glicken was born in 1958 to Milton and Ida Glicken. He graduated from Stanford University in 1980. Later that year, while a graduate student at the University of California, Santa Barbara, he was temporarily hired by the United States Geological Survey to help monitor the volcano Mount St. Helens in Washington state. St. Helens, dormant since the 1840s and 1850s, resumed activity in March 1980.
