Explosive volcanism: Inception, evolution, and hazards
One purpose of the studies is to provide assessments from the scientific community to aid policymakers in decisions on societal problems that involve geophysics. An important part of such an assessment is an evaluation of the adequacy of present geophysical knowledge and the appropriateness of present research programs to provide information required for those decisions. Some of the studies place more emphasis on assessing the present status of a field of geophysics and identifying the most promising directions for future research. This study on explosive volcanism was begun soon after the cataclysmic eruptions of Mount St. Helens. It readily became apparent to the committee that an assessment of the explosive nature of volcanoes must cover all types of volcanic activity; any volcano can be explosive. Improved understanding of the physics of volcanic eruptions is an exciting goal that is vital to progress in hazard evaluation. The study of explosive volcanism must include an appreciation of the severe social problems that are caused by erupting volcanoes. None is of greater urgency than planning for a crisis. This report considers the progress in research on these aspects of explosive volcanism and the need for additional research efforts. This volume contains 13 papers. Topics include tectonism, volcanism, volcanic periodicity, eruptive mechanics, emergency planning and recommendations. Individual papers are indexed separately on the energy data base.
