Today this is on everyone's mind as we have seen the pictures coming out of Chile. Our prayers and concers are with these people.
When it comes to EQ preparedness I don't know if we can ever be totally prepared, but there are things we can do ahead of time to help if this happens to us and our families.
When I was about 5 we lived in Salt Lake City, Utah. There was a huge earthquake. I remember trying to get to my mom's room. It was quaking so hard that by the time my brother and I reached the hallway that we were being thrown from wall to wall. My mom yelled to us to lay down. We did that until the shaking finished.
I would suggest if you have children to talk to them about what they do during the earthquake specifically. Let them practice it. Make it a fun night so they aren't scared. Going through this as a child and knowing the terror this created I know how little kids just try to get to their parents. We never talked about earthquakes and what to do if there was one and it was terrifying. If we had talked about it, I would have better known what to do.
