| Abstract: | This study assesses natural disturbances at Puerto Rico resulting from hurricane Georges in September 1998. The study was done using data from the National Oceanic and Atmospheric Administration's Advanced Very High Resolution Radiometer (AVHRR) 14 satellite. Specifically, the Luquillo Experimental Forest, the Guanica Dry Forest and five cities were examined using AVHRR data. It was found that although there is probably no significant relationship between Georges and the before/after temperature data, there is a statistically significant relationship between distance to the location affected by the hurricane and the extent of changes in NDVI, a fact that suggests that it is possible to measure hurricane impacts on vegetation by using AVHRR data. |
