I live in Mendoza (Argentina) next to Chile, we are separated only by the Cordillera de los Andes. We didn't feel the earthquake from here. It was in the north. That made alert many cost countries like Peru, Ecuador and Colombia.
8,2 is damn strong. And I have heard they have Replics every 6 minutes. I still can remember the last earthquake they had some time ago with a tsunami too.
I agree that we dont have the way to support an earthquake with that rate. Chile really surprised me the way they stand up in a short period of time. IMO, they are a strong country, but unfortunately it took lot of human life.
So many people disappeared, they lost all they had in a second.
Really sad, my prayers for them.
