This chapter provides an overview of the geographic information systems (GIS) methods and techniques commonly employed by researchers of natural hazards. In doing so, each section will provide a brief overview and summary of the tools discussed, common questions that can be addressed by the tools, and examples from researchers who have applied those tools in actual cases of hazards and disasters. This chapter is by no means an exhaustive overview of all the tools at our disposal. Instead, this chapter provides an initial overview of the commonly used spatial tools to familiarize students and researchers on how GIS tools and techniques can be applied to studying natural hazards.
