N2 - Volcano monitoring using satellite images may provide periodic information on gas emission fluctuations such as S0inf2/inf emissions related to the processes occurring inside volcanoes. This study analyses a period of 36 days (May 10 to June 15, 2005) of processing 113 MODIS images for the detection of S0inf2/inf. Within this period it was also possible to detect and quantify 8 of 15 explosive events reported by the Washington VAAC. With the satellite images as tools for monitoring the volcanic emissions, it was possible to determine three cases related to volcanic ashes: 1) follow up of volcanic ash and gases transported by wind, 2) calculation of ash-cloud residence time in the atmosphere, 3) effects of shearing winds during the ascent of an ash plume. Regarding the continuous monitoring of passive emissions of S0inf2/inf, there is a relationship among explosive events and increasing peaks of S0inf2/inf emission suggesting a difference of approximately 2 days between the two events that may anticipate the type of behavior of the volcano.
