The ground. Is the boom. Earthquakes are wierd you can hear them coming.
Had one in Alaska it was a rolling quake. Heard it coming and the ground actually lifted like something was rolling underneath it.
Dang that is sad to hear. We met up for a Nascar race one time and I lost a bet and had to have her picture in my avatar. Was friends with her on Facebook but didn't know she passed away. Very sad to hear.
