Woodquakes

Caption

Year rings show collapse as a result of the piston's compression. The images taken by the camera clearly display the year rings of the wood. Comparing two consecutive images reveals the collapse of a year ring. This is seen in the picture on the right as a dark red stripe, which signifies a large local deformation.
