The Universidad Carlos III de Madrid’s (UC3M) Displays and Photonic Applications Research Group has developed a measuring instrument that can be used to study the increase in temperature during volcanic eruptions. This research allows the first measurements of temperature to be taken in situ using a machine in the laboratory that simulates these volcanic processes. The measurements that can be taken have enough spatial and temporal resolution to provide information about the sliding mechanics of a seismic fault. Until now, there has not been an effective experimental technique for measuring the temperature at the eruption site.
