Christchurch Earthquake

There have been a lot of pictures of the devastation, some of which I have shared elsewhere. However, this picture below is different as I think it shows the acceleration and force. I lifted the remote control off the couch about an hour after the quake, and expected to find a clean outline of the remote (dirt flew from everywhere and has totally embedded in the couch).

However, what I found was that not only the outline of the remote, but the buttons had been impressed into the couch. Given that nothing fell on the remote to drive it into the couch, the only explanation was the force of the quake lifted and drove the couch into the remote at such an acceleration that the remote didn’t bounce but became imbedded into the couch!
