Summary

Caption: One group of USGS scientists is being met by another scientist on May 2, 1980 waiting to leave by helicopter to make further studies of Mount St. Helens before the main eruption of May 18, 1980. Aerial observations and photographs as well as instrument readings are the primary tools used by the USGS in studying the Cascade Mountain Range volcano in Washington state. According to the USGS, the vast amounts of data collected from the eruption, one of the most highly studied events of its kind, will be useful in improving not only the understanding of volcano dymanmics but also the predictive capabilities for future eruptions. Note: David A. Johnston, USGS volcanologist, facing helicopter. PIO No.: 80-147b (2d)
