Seismic monitoring systems and satellite remote sensing are promising measures for rapid assessment of seismic damage distribution. To make the best of both information, considering the trade-off of promptness, precision and spatial resolution, a Bayesian method to synthesize seismic intensity distribution and remote sensing image has been proposed for post-earthquake early detection of building damage areas. Damage probability estimated by use of seismic intensity distribution and fragility relations serves as a prior information for Bayesian updating procedure. The satelite SAR intensity image is then incorporated to update the initial estimation, providing more reliable estimation of damage distribution.
