So far there is only one confirmed dead, but we're afraid there will be many more. The latest guess is that there are 51 residents unaccounted for.
WPLG in Miami has a very graphic surveillance video of the collapse, but I'm not going to link it. First, a large part in the center of the building collapsed, and then a remaining North wing of the building fell a few seconds later. There are more than 130 apartments in the building and I'd estimate that close to 1/2 of them are gone. When you view that video, you know there are going to be a lot of deaths.
One good thing we have going for us is that both Miami-Dade Fire Rescue and Miami Fire Rescue have some of the best urban search rescue specialists in the world. They both send teams whenever there is a big earthquake or other disaster overseas.
