In Chile they have, and have had for a long time, very strict building codes. They know they are in an earthquake zone and plan accordingly. And, there is very little corruption in Chile - so no way to bribe building inspectors and get away with substandard work. (My ex sister in law is an architect in Chile - that's where I got this info). With an earthquake of this magnitude there's going to be damage, especially with older buildings, but it won't be nearly as bad as it would be if the buildings weren't sturdy and as earthquake proof as possible.
