This Liquib scene shows the destruction that can be quickly inflicted by the Crater Effect.  Numerous Craters and Pits were applied, with random positioning, and other randomly chosen characteristics including Cause, Size, Irregularity, Magnitude and Hole, Rim and Splatter varients.  Notice how the more recent Craters and Pits have partially displaced and distorted the older ones, along with any other portions of the image where they were dropped.  After being initiated, Splatters will begin ejecting from each Crater and Pit.
