We demonstrate monitoring of H2O and CO2 emitted in a volcanic area, using a spectrometer equipped with two distributed feedback (DFB) semiconductor diode lasers. Each laser is resonant with a molecular species and is fiber-coupled to allow remote operation of the spectrometer. Recordings of H2O and CO2 lines made at the Solfatara volcano, in southern Italy, are shown, and the application of such a spectrometer as a new tool for the continuous monitoring and surveillance of volcanoes is discussed.
