Explosive volcanism: inception, evolution, and hazards. Final report

OSTI ID:5073940

Explosive eruptions can occur in any volcanic system. An increased understanding of the physical and chemical processes responsible for magma generation, evolution, and eruption is important for improving the reliability of volcanic hazard predictions. In addition, for particularly dangerous volcanic areas, a data base covering the nature and sequence of historic and prehistoric eruptions is invaluable. The existence of such a data base for Mount St. Helens permitted prediction of the nature of the eruptive events of 1980 with remarkable success. However, predictions of the imminence of eruptions require extensive geophysical monitoring. The study also points out that an important aspect of volcano prediction and warning is the communication of the necessary information to civil officials and the public.
