This image could be called “Before and After the Earthquake” As can be seen the glyph on the top right side and along the bottom were most likely carved before the rock ledge fell into it’s current position. As this area is an earthquake zone, the forces generated by an earthquake probably broke it. Following this the images on the central and left upper parts were carved, as they are orientated to be vertical in the rock’s current position.
