An exploration of the Bam earthquake in Google Earth (v1.0.1)

(There will be images when I get around to posting them...)

Before the earthquake: field visits to the Bam area by Richard Walker and James Jackson of the University of Cambridge identified a potential active fault.

The earthquake struck a little after 4 am local time on 26th December 2003. The NEIC focal mechanism was consistent with either E-W left-lateral or N-S right-lateral strike-slip on a vertical fault. The moment magnitude (Mw) of the quake was 6.6; peak vertical ground accelerations recorded in the city were 0.97g, with a S-P time of 1.9 seconds.

Three days after the earthquake, James Jackson and Morteza Talebian (Geological Survey of Iran) arrived at Bam for a post-earthquake survey. Is the observed damage to the buildings that they saw consistent with a magnitude 6.6 earthquake? What about the damage to the ground (the surface ruptures)?

Two weeks after the earthquake, the first InSAR data became available. Over the coming weeks, two interferograms were constructed which showed a four quadrant deformation pattern.

Aftershock data, collected by Denis Hatzfeld (Grenoble) from one week to four weeks after the earthquake were released in mid February, 2004. What do they say about the location of the active fault?

In late February, a team from the Geological Survey of Iran returned to Bam in order to make more field observations. What did they see in their photos?
