Thesemeasurements were obtained using images from Advanced Spaceborne Thermal Emission and Reflexion radiometer, Ozone Monitoring Instrument and a ground-basedUV camera. These three very different instruments provide flux measurements in good agreement with each other, which demonstrate that they can be integrated for monitoring SO2 fluxes. Fluxes from Turrialba increased fourfold in January 2010, following a phreatic explosion that formed a degassing vent in the W crater of Turrialba. Since then, the SO2 flux has remained high (30–50 kg/s) but seems to be showing a slowly decreasing trend. We interpret this evolution as the start of open vent degassing from a recently intruded magma body. The opening of the degassing vent decreased the confining pressure of the magma body and allowed the gases to bypass the hydrothermal system. Mediciones de dióxido de azufre por teledetección (SO2) emitido por el volcán Turrialba (Costa Rica) se reportan para el período de septiembre de 2009 a enero de 2011. Estas mediciones se obtuvieron utilizando imágenes del radiómetro avanzado de Reflexión y Emisión Térmica Espacial, Ozono Instrumento de monitoreo y una cámara UV en tierra. Estos tres instrumentos muy diferentes proporcionan mediciones de flujo en buen acuerdo entre ellos, lo que demuestra que ellos puede ser integrado para monitorear los flujos de SO2. Los flujos de Turrialba se multiplicó por cuatro en enero de 2010, tras una explosión freática que formó un respiradero desgasificador en el W cráter de Turrialba. Desde entonces, el flujo de SO2 se ha mantenido alto (30-50 kg/s) pero parece estar mostrando una lenta disminución tendencia. Interpretamos esta evolución como el comienzo de la ventilación abierta desgasificando de un cuerpo de magma recientemente invadido. La apertura del respiradero de desgasificación disminuyó la presión de confinamiento de la cuerpo de magma y permitió que los gases pasaran por alto el sistema hidrotérmico.
