That's just a guess by a paper, but it would be up there with Tangshan, China. When I first saw it flash by on the ticker-tape, I estimated tens of thousands, but I don't really know the total population of the area.
Here's where it gets depressing, and outside of scientific inquiry. There's nothing to learn here, we've seen this again and again. I hope they can figure out housing which can withstand earthquakes and hurricanes. I'm not going to report on this anymore. Your ad clicks can stop me from sliding into depression. :) :( :) :) <=== bipolar!
