![]() ![]() They can be used to forecast the cost of volcanic activity, which may be helpful in securing budgeting for mitigation efforts. a year, is developed and shared using an internet world wide web vehicle, which facilitates some complex overlays.Īlthough volcanic hazard maps are now available at many hazardous volcanoes, volcanic risk maps are very rare and may offer some special advantages in Volcanic Hazard Communications efforts. The map, which shows the cost of the volcano to the Guatemalan government, to be between 3.3 and 8.4 million dollars U.S. The goal is to present on a single map, the risks of volcanic activity in terms that the public can better understand. We have prepared a GIS array for the volcano and its surroundings, which combines volcanic hazard zonations with four layers of economic and population data (population, infrastructure, land use, and standard of living). Michigan Technological University, Houghton, MIĮ-mail: I Rose (Geological Engineering, Michigan TechnologicalĮ-mail: María, an international decade volcano in Guatemala, presents significant volcanic hazards to its surrounding populations from its activity, which has been continuous since 1922. (School of Business and Engineering Administration What can Risk Maps Contribute to Volcanic Volcanic Risk Map for Santa María, Guatemala: Remote Sensing at Michigan Tech, and is a part of an effort to map changing This image was processed by Paul Kimberly at the Laboratory of Atmospheric The blue tones highlight the volcano and the areas of hazard associated withĬonsequent sedimentation along the Rio Samalá and other rivers of theĪggrading alluvial fan of volcanic sediments south of the volcano all the way The false color image shows heavily vegetatedĪrea in green tones, agricultural areas in red and unvegetated rock as blue. The volcano itself is located at the upper right of theįigure, and a transparent eruption cloud (white) which is drifting to the south of the volcano can also be seen. The image shows the entire volcanic hazard zone associated with Santa María Volcano, extending downslope to the south from the volcano (3770 m elevation)to the sea level. ![]() The false color display has band 5 displayed in red, band 4 This Landsat Thematic Mapper image (ID # 5021050009504010) was collected onįebruary 9, 1995.
