Review of the utility of infrared remote sensing for detecting and monitoring volcanic activity with the case study of shortwave infrared data for Lascar Volcano from 2001–2005

Abstract

Abstract 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.
