Urban built-up area is a typical human-natural system that balances itself intrinsically via complex interaction on structural and social matters. Studying the resilience of this system is particularly important for sustainable development. Current studies mainly rely on the analysis of social-economic data collected from various sources. Few studies have evolved ideas of utilizing the physical appearance of urban built-up area as cues of resilience indicator. The objective of this paper is to investigate the use of very high resolution (VHR) satellite images to characterize resilience of urban built-up systems in an area affected by the 2010 Haiti Earthquake. Our approach follows the concept of “Equilibrium Analysis” by mapping the recovery progress of an earthquake impacted area using yearly VHR satellite images. The dynamics of critical urban elements such as permanent buildings, temporary lodging will be analyzed to derive critical indicators of urban resilience and understand how it recovers from earthquake.
