Resumen
El monitoreo volcánico busca entender mejor los sistemas volcánicos, para poder realizar predicciones de su actividad. Las técnicas de monitoreo incluyen el sísmico, de deformación, de gases, hidrológico, y visual, entre otros. El monitoreo de gases es importante, entre otras razones, porque nos provee información sobre la dinámica y evolución de los sistemas magmáticos e hidrotermales. Las medidas se pueden hacer de forma directa o por métodos de percepción remota (en superficie o satelital). Aquí nos enfocamos en los principales métodos de percepción remota en superficie, que se usan actualmente en volcanes. Estos incluyen el espectrómetro de correlación (COSPEC), el DOAS, la cámara ultravioleta y el espectrómetro infrarrojo de transformada de Fourier (FTIR). Cada una de estas técnicas tiene ventajas y desventajas, y para entenderlas, aquí se describen los aspectos generales de cada una, incluyendo métodos para conducir las mediciones, las fuentes de error y algunos ejemplos de estudios hechos.Citas
