Regional volcanic hazard investigations require an in-depth understanding of a region’s spatial and temporal distribution of volcanic vents and variations in eruption rates. Usually assessments are based solely upon the distribution of vents and eruptive centers exposed at the surface. These assessments commonly assume relatively simple tectono-magmatic settings and evolutions (e.g. Connor et al., 1992; Conway et al., 1998). Hazard studies within tectonically complicated regions, such as the Basin and Range of the western US (e.g. Yucca Mountain, Connor et al., 2000; Valentine and Perry, Chapter 19, this volume), have demonstrated the need for more accurate knowledge of the regional volcanic stratigraphy. In this chapter, we describe an analysis of volcanic hazards that includes this more comprehensive view of volcano stratigraphy. Such detailed investigations, accounting for differential subsidence and the burial of older volcanic features, can vastly improve the accuracy of any volcanic hazard assessment.
