1980 : INDONESIA, USA

The May 18 eruption of MT. SAINT HELENS was the best-observed eruption ever, and surviving volcanologists learned a great deal about the dynamics of edifice collapse and formation of volcanic blast-deposits. I spent a few days helping my USGS colleagues in their post-eruption work that summer, but soon found myself in Indonesia, where a relatively small eruption of GAMALAMA Volcano had caused the exodus of the island of Ternate. Most of my efforts were devoted to convincing refugees that it was safe to return, but during our stay on Ternate, my Indonesian colleagues and I produced the first-ever detailed geologic map of any volcano in Indonesia.
