Unfortunately, there are two distinct classes in that area: The rich and the poor. Needless to say, the rich have better buildings and even some of those came down. You can imagine what it's like for the others! Of course, building your city on a dry lake bed in a high seismic zone isn't the smartest thing either. When the ground shakes, the sand basically turns into a liquid and acts like a drum head amplifying the movement and providing no support...
One of my clients have a couple of translators down there and they had to stay outside until their building was cleared for them to reenter. Just heard that they'll be able to continue work about 30 minutes ago.
