My entire family (with the exception of one of my brothers, cousins and grandmother) lives in Chile. Unable to communicate with anyone, we have been using Facebook as a means to pass information along with other family members to update each other on their current situations. To time, I have received the news from my cousins and aunts that everyone is okay. They have suffered minor damages to personal possessions, but they are all safe.
But I've yet to hear anything from my other brother, and the phone lines are still down. Because Chile has a long history of natural disasters, the government is more prepared in coordinating relief and rescue efforts. I am therefore confident that my brother and his family are okay as well.
I hope that the casualties aren't overwhelming, and that many more survivors are rescued.
