| Research Abstract |
In this study, we developed a system that enables us to locate the possible impacted area due to significant earthquakes which occur anywhere in the world based on nighttime lights observed by the Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS) within the first 24hours after the event. The estimation is based on the detection of significant reductions or loss of lights in two consecutive nighttime images that one is taken before and one right after the event, for it can be expected that city lights will observably decrease after a large earthquake due to various reasons such as electricity failure, building collapses, evacuation to shelters and the suspension of commercial activities. This system goes through the following processing steps : 1) acquiring the earthquake hypocenter data through the Internet, which is for example announced by the USGS, 2) determining the sampled area of images by the attenuation formula of earthquake ground motion, 3) selection and download of the corresponding nighttime DMSP/OLS data from National Oceanic and Atmospheric Administration, National Geophysical Data Center (NOAA/NGDC), 4) estimating the damaged areas by analyzing the statistically significant decrease in light intensity of the images, 5) creating the thematic map to present the estimation results as geographic information, and 6) disseminating the result map widely and quickly through the WWW.The validity of our estimation has been established for some recent earthquake disasters such as the 1995 Hyogo-ken Nanbu Earthquake in Japan, the 1999 Kocaeli Earthquake in Turkey, and the 1999 Chi-Chi Earthquake in Taiwan.
