My Master’s project used high-resolution digital photographs and infrared images to monitor the growth and thermal evolution of the Volcan de Colima (Mexico) lava dome, from 2007 to 2010. Qualitative observations from the thermal images themselves provided much insight into active volcanic processes on the dome (e.g. rockfalls and fracturing). Thermal data was also used quantitatively to measure surface temperature changes and dome heat loss through time.
