Thermal imaging using infra-red cameras is now a widely used tool in the monitoring and analysis of volcanic explosions, and this pair of time-series snapshots of two short-lived ‘Vulcanian‘ explosions at Volcán de Colima, Mexico, shows one example of why. In each panel, times (in seconds) are times since the start of the explosion sequence; and the temperature scales (vertical colour bar) show the raw temperatures, without any atmospheric corrections. Images collected using a Jenoptic VarioCAM, from the Protección Civil de Jalisco observatory located beneath the summit of Nevado de Colima, Mexico.
