> buildings are designed to withstand them

that's what they said there too.

and shouldn't the home builders should go to study those holding up a 7.8 magnitude quake.

It certainly could be either. In the parts of America that have lots of earthquakes, buildings are designed to withstand them, but I can't speak to the situation in Turkey.

but the interesting thing is even within the same area, you might have a few still perfectly standing among the collapsed ones, I assumed it could be 
a. it depends on the bedrock 
b. it depends on how it is being built

It's possible those older buildings were built on the most stable ground. There's a big difference in how much earthquake damage is done to buildings standing on bedrock vs those built on dirt.
