Damage Assessment with Very-High Resolution Optical Imagery Following the December 26, 2003 Bam, Iran Earthquake

چکیده
This paper presents a methodology for quantifying the number of buildings that collapsed following the Bam earthquake. The approach is ‘object’ rather than ‘pixel’-oriented, commencing with the inventory of buildings as objects within high-resolution Quickbird satellite imagery captured before the event. The number of collapsed structures is computed based on the unique statistical characteristics of these objects/buildings within the ‘after’ scene. A total of 18,872 structures were identified within Bam, of which the results suggest that 34% collapsed a total of 6,473. Preliminary assessments indicate an overall accuracy for the damage classification of 70.5%.

Interferometric Displacement and Damage Assessment for the 2003 Bam Earthquake
We demonstrate that interferometric observations of the Mw6.6 Bam (Iran) earthquake on December 26, 2003 acquired by Envisat-ASAR can not only map surface displacements and constrain fault models, but can also be used for damage mapping using the coherence magnitude. The Bam earthquake was the deadliest earthquake in 2003. An estimated 30000 people were killed and 85% of the buildings in the ar...

متن کاملEstimation of Earthquake Damage Through Radar Interferometry (Case study: Bam 2003 Earthquake)
The estimate of the damage caused by the earthquake and other natural disasters in the first days after the occurrence of these events can provide a quick damages assessment and help to manage the crisis. Several methods are available to investigate the extent of earthquake’s damage. Optical remote sensing, photogrammetric methods (UAVs and LIDARs), radar interferometry (InSAR) and field observ...
متن کاملComparison of Earthquake Damage Evaluation using Change Detection and Thematic Classification
Because of the availability of high-resolution satellite imagery, remote sensing data has become an attractive source of data for identifying post-earthquake damage. Recently, several semiautomated methods for earthquake damage detection have been developed. These methodologies fall into two general categories: change detection and thematic classification. In change detection, both preand post-...
