Abstract

Due to the dangerous and remote nature of many volcanoes, field-based data collection of active
processes and precursory activity is problematic. Spaceborne remote sensing instruments enable
these data to be recorded, monitored, and studied. The Advanced Spaceborne Thermal Emission
and Reflection Radiometer (ASTER) is one such sensor that currently collects data in the visible
near infrared (VNIR) and thermal infrared (TIR) wavelength regions and has an archive with the
highest spatial resolution TIR data (90 m) currently available to the scientific community. ASTER
is capable of recording precursory volcanic activity that is unidentifiable with other sensors. By
combining ASTER data with those gathered from the Advanced Very High Resolution Radiometer
(AVHRR) and the Moderate Resolution Imaging Spectroradiometer (MODIS), temporal resolution
is improved and processes such as the cooling rate of pyroclastic flows and subtle precursory
activity are able to be quantified. Rigorous modeling of these datasets further allows results such
as estimation of pyroclastic flow volume, the specific eruption mechanisms and the onset of a
future eruption. The work outlined in this dissertation demonstrates how data collected from the
ASTER sensor greatly improves current monitoring capabilities. New methods for processing
these high spatial resolution data allow scientists to understand and better evaluate the risks
associated with specific volcanoes and their common eruption styles.
