Could be a contributing factor. Geological conditions in many parts of Florida are dangerous. Limestone and a long, long history of sinkholes. Large ones. Deep ones. Since the condo is that near the beach, it could well be an undersea cavern cave-in. Would be interesting to see the foundation construction records -- soil testing etc.
Or, if you prefer, maybe someone put a bomb in the undersea cavern and detonated it. Plausible. I'm not even ruling out a well-placed bomb (need to be well placed to cut concrete and steel.) But there is no credible talk of bombing evidence as yet, and is becoming less and less likely the longer time goes by. So the geological cause is currently the more credible theory.
The suvr vid showed that it was one section that started the collapse, then it went part-by-part. The cave-in did not have to be very large. The building didn't look like an earthquake-proof structure. Once support pillars went in once place, floors started to collapse but stronger parts like lift shafts held.
There is talk of a sinkhole as the cause. Plausible, 'cause Florida.
except that's not what a sinkhole looks like
Ground just need to shift enough to make the pillars on one side fail. It would be impossible to see anything because of the rubble.
That's the current talk anyway.
Note that a 3+ "earth quake" was caused last week in FL by offshore military test. Hmmmm.
