2004年12月26日，印度尼西亚苏门答腊岛北部西海岸发生9.2级地震，造成16万印度尼西亚人死亡。我们研究了2004年至2008年在苏门答腊岛进行的海啸灾后恢复研究（STAR）中的307个社区的国防气象卫星计划-操作直线扫描系统（DMSP-OLS）夜间灯光图像亮度值。我们检查了年度亮度和损害程度之间的夜间照明时间序列，从STAR家庭收集的经济指标并汇总到社区水平。2004年至2008年的亮度值有显著的变化，2005年的亮度值明显下降，因为海啸和海啸前的夜间亮度值在2006年恢复。夜间图像亮度与人均消费、能源消费和食物消费之间存在显著关系。结果表明，国防气象卫星计划的夜间灯光图像可以用来捕捉海啸和其他自然灾害的影响和恢复，并估计发展中国家社区一级的时间序列经济指标。
On 26 December 2004, a magnitude 9.2 earthquake off the west coast of the northern Sumatra, Indonesia resulted in 160,000 Indonesians killed. We examine the Defense Meteorological Satellite Program-Operational Linescan System (DMSP-OLS) nighttime light imagery brightness values for 307 communities in the Study of the Tsunami Aftermath and Recovery (STAR), a household survey in Sumatra from 2004 to 2008. We examined night light time series between the annual brightness and extent of damage, economic metrics collected from STAR households and aggregated to the community level. There were significant changes in brightness values from 2004 to 2008 with a significant drop in brightness values in 2005 due to the tsunami and pre-tsunami nighttime light values returning in 2006 for all damage zones. There were significant relationships between the nighttime imagery brightness and per capita expenditures, and spending on energy and on food. Results suggest that Defense Meteorological Satellite Program nighttime light imagery can be used to capture the impacts and recovery from the tsunami and other natural disasters and estimate time series economic metrics at the community level in developing countries.
