Harry Glicken (1958–1991) was an American volcanologist who researched Mount St. Helens before and after its dramatic eruption in 1980. Despite a long-term interest in working for the U.S. Geological Survey, Glicken never received a permanent post there because employees found him eccentric. Conducting independent research sponsored by the National Science Foundation and other organizations, Glicken accrued expertise in the field of volcanic debris avalanches. He wrote several major publications on the topic, including his doctoral dissertation on Mount St. Helens. In 1991, while conducting avalanche research with volcanologists Katia and Maurice Krafft on Mount Unzen in Japan, Glicken was killed by a wayward pyroclastic flow. Glicken and David A. Johnston (who died at Mount St. Helens) remain the only American volcanologists known to have perished in volcanic eruptions. After Glicken's dissertation was published by his colleagues in 1996, the report was widely cited. His detailed and comprehensive work on flows at Mount St. Helens is considered the most complete in the field to date.

___________________________ Wikiquote quote of the day:

The fullness of grace can transform the human heart and enable it to do something so great as to change the course of human history. … This Extraordinary Holy Year is itself a gift of grace. To pass through the Holy Door means to rediscover the infinite mercy of the Father who welcomes everyone and goes out personally to encounter each of them. This will be a year in which we grow ever more convinced of God’s mercy. How much wrong we do to God and his grace when we speak of sins being punished by his judgment before we speak of their being forgiven by his mercy! But that is the truth. We have to put mercy before judgment, and in any event God’s judgement will always be in the light of his mercy. In passing through the Holy Door, then, may we feel that we ourselves are part of this mystery of love. Let us set aside all fear and dread, for these do not befit men and women who are loved. Instead, let us experience the joy of encountering that grace which transforms all things.   --Pope Francis https://en.wikiquote.org/wiki/Pope_Francis
