Maps risk generations for volcanic ash monitoring using modis data and its aplication in risk maps for aviation hazard mitigation: Case of study popocatepetl volcano (Mexico)

摘要

The volcanic products are deposited in the atmosphere as a result of volcanic eruptions. These materials are dispersed by the wind and can be deposited on the surface in airport facilities and the finest fraction can remain long affecting airspace. Using tools such as wind patterns studio in height and track volcanic clouds with satellite images can identify areas of high probability of being contaminated with ash depending on the season and the intensity of the eruption. In this work two patterns of ash dispersion by wind are identifiedNovember to May transporting the ash has a higher probability NE to the ESE direction. During the months of July to September transporting ash would displace mainly towards the SW to W, with the months of May and October transition.
