CNN)At least 159 people were unaccounted for Friday, a day after the collapse of part of a 12-story residential building in Surfside, Florida, authorities have said. 

Search and rescue teams have been feverishly scouring the site since shortly after 55 of the building's 136 units fell. Four people are dead, officials have said.

Here's what we know about the missing.

One hundred fifty nine people are unaccounted for.  I think most of them

are dead. "Pancake Collapse" did not give any space for the people to

survive. Something like this could happen in U.S.. Apparently 

the inspection carried out the day before failed to detect forewarning 

signs. I am afraid that it was built on the ground that should have not 

been built by the builders who were greedy for the profit. 
 

By the same token, Wawu apart in 1970 Korea collapsed because of corruption

was also caused by the human greediness seeking for the profit.

건물 밑바닥은 모래와 침전물로 돼 있는데, 해수면이 오르면서 침전물이 빠져나갔고 침하를 일으켰다는 것이다.

No wonder why many call the people in the construction business is crooks with no responsibility. So they built such high rise buildings literally on the sand!!

I think all ocean side properties needs to be thoroughly inspected. 
The sea level has risen so much in the last 100 years that the foundation 

of the building in the shore lines could be in trouble. 
 

American's appetite for the water front properties caused the builders put up 

houses and high rise buildings too close to the water. Now they are paying 

the price. 

You are certainly right!

Further, the insurance coverage encouraged such crazy behavior. We do see the same thing after each hurricane, every year!!!
