An accelerometer within the dropped zone of the rift recorded 120 cm/s. This is an incredible level, and no normal building can take it.
You can see it's a giant pulse, and it is my main contention with standard earthquake engineering, which relies too much on shake tables. As well, this is on soil, so the key to building here would be deep foundations where you would get a factor of 10 reduction in the PGV.
I don't think there will be any lessons learned here, mainly because of the building standards. However, it was well recorded.
