A PROPOSED ALERT-LEVEL NOTIFICATION SCHEME FOR AVIATION AND GROUND-BASED HAZARDS AT U.S. VOLCANOES

This paper discusses a proposed alert-level notification scheme for activity at United States volcanoes monitored by the U.S. Geological Survey's Volcano Hazards Program (USGS-VHP). The goals and motivation of the scheme, the rationale for the different alert levels, and the way in which it is incorporated into the USGS-VHP's overall mitigation strategy to notify the public about potential eruptions of volcanoes are discussed. The function of hazard alert schemes is to give the public and public officials warning about the proximity of a hazardous event. The precision of the warning depends on the nature of the hazardous event. Volcanoes do not erupt with consistent precursors, or in a uniform manner; nor do all episodes of unrest result in an eruption. Therefore there is a great deal of uncertainly in evaluating future volcanic behavior at restless volcanoes. These uncertainties impact how precise the volcano notification schemes can be, and present a challenge to their development.
