I was actually involved in this project. I shit you not.
It was done with a Dodeca 2360 camera system which is the same camera system used by google street view. I was contacted a couple days after the quake and contracted to build 3 sites for a new partnership between my client (he bought the cams and shot the video), the manufacturer, and a 3rd silent partner.
If you wanna buy a system, here it is:
