Advanced Research on Potential of Remote Sensing – A Review Based on Natural Disasters Occurred during the Last Decade in Chile
Chile has been suffering from a number of natural disasters over the past decade. Via natural disasters that have occurred in Chile over the past ten years, it is demonstrated how observations gained by various currently available Remote Sensing sensors have been successfully used on many occasions. The examples given in this article are based on the February 2010 earthquake and tsunami and the 2008 and 2011 volcanic eruptions, 2012 forest fires and 2010 droughts. In addition, the most important remote sensing platforms for current disaster management are also presented. Although the most well-known public application is damage registration, Remote Sensing can also be used in all the other stages of a modern disaster management cycle: prevention, preparedness, response and recovery. This article therefore also explains how and under which situations remotely sensed data can be useful. As Remote Sensing can be considered one of the most effective instruments in the field of natural disaster management, we conclude that its use must be increased in a country like Chile to resolve any kind of natural disaster and its devastating effects. Remote sensing is expected to be an even stronger and more useful instrument in the management of natural disasters in the future, owing to the availability of continuously collected images and increased spatial and spectral resolution of satellite observations.
