This chapter provides a historical review of the use of infrared remote sensing for the monitoring of volcanic activity. It (1) examines the theoretical basis for infrared observations of thermally anomalous volcanic features, (2) presents the various sensors that have been used and are currently available and (3) describes the techniques that have been developed to analyse such data. The chapter ends with a case study of data derived from Advanced Spaceborne Thermal Emission and Reflection Radiometer shortwave infrared observations of Lascar Volcano in Chile. This case study aims to highlight the utility of infrared observations in volcanological studies, assessing the various techniques that can be used and examining the different factors which influence these analyses. The chapter ends discussing future prospects for volcanic infrared remote sensing.

Remote Sensing of Volcanoes and Volcanic Processes: Integrating Observation and Modelling
Volcanoes have played a profound role in shaping our planet, and volcanic activity is a major hazard locally, regionally and globally. Many volcanoes are, however, poorly accessible and sparsely monitored. Consequently, remote sensing is playing an increasingly important role in tracking volcano behaviour, while synoptic remote sensing techniques have begun to make major contributions to volcanological science. Volcanology is driven in part by the operational concerns of volcano monitoring and hazard management, but the goal of volcanological science is to understand the processes that underlie volcanic activity. This volume shows how we may reach a deeper understanding by integrating remote sensing measurements with modelling approaches and, if available, ground-based observations. It includes reviews and papers that report technical advances and document key case studies. They span a range of remote sensing applications to volcanoes, from volcano deformation, thermal anomalies and gas fluxes, to the tracking of eruptive ash and gas plumes. The result is a state-of-the-art overview of the ever-growing importance of remote sensing to volcanology.
