Right, that was the point I was trying to make, perhaps I didn't state it well. Seek shelter immediately and try to avoid flying glass. I would also avoid UMBs (Unreinforced Masonary Buildings) these buildings WILL collapse. They aren't as common in FiDi but are all over Soma, Chinatown, and the Tenderloin.
Yeah. Lots of stuff comes from above if you are on the street. Going inside a building is a good bet.
"35 deaths and many injuries from falling masonry during the 2011 Christchurch earthquake. Buildings with dangerous parapets, facades and verandahs" [1]. That was 20% of total deaths.
Certainly near a skyscraper, you want to go inside, since if it pancakes, being outside won't help anyway - debris will hurtle horizontally.
