- Abstract:
-
The DMSP/OLS night-time lighting imagery is a direct manifestation of the power failure after a strong earthquake. Based on the lighting image feature analysis before and after an earthquake,this paper establishes a simple and practical method to extract the information of earthquake disaster. The method is tested in the 2001 India M7.6 earthquake and the 2011 Japan M9.0 earthquake and gets good results. The results show that the night-time imagery change detection method based on the significance test is simple and effective. The use of the night-time imagery data can not only obtain the extent of earthquake damage from the macro level,but also directly reflect the scale and spatial distribution of the affected population after an earthquake. Therefore,the night-time imagery data can be used as a valuable earthquake disaster to get information sources quickly.
