Abstract: This paper presents a damage estimation model suitable for evaluating earthquake damage using coherence images derived from interferometric SAR data. The damage degree is estimated through temporal decorrelation by employing a coherence ratio which is defined by dividing a post-event coherence image by a pre-event image. The temporal coherence ratio is confirmed to be closely correlated with the probability of the damage degree. As a result of applying both C and L bands SAR data for evaluating the damage of the 1995 Hyogoken-Nanbu Earthquake in Japan, the cumulative probability of the damage degree can be approximated by a linear function of the coherence ratio.

TL;DR: It is found that there is decorrelation increasing with time but that digital terrain model generation remains feasible and such a technique could provide a global digital terrain map.

TL;DR: The coherency is important for detecting the damaged urban area using the correlation of SAR data because the major factor in the intensity decorrelation is still related to the interferometric decorrelation process, namely, the change of speckle patterns due to thechange of urban surface patterns.
