Each color fringe represents 1.55 centimeters (0.61 inches) of ground movement in the direction between the satellite and the ground (range change). The symbol in the upper left indicates the satellite's orbit direction (arrow) and look direction (bar). Earthquakes are marked with circles with the size proportional to their magnitude. The lava flows covering the crater floor are represented by the pink polygon, the two vents (circles) and the Episode 30 fissure (line) are marked in light pink.
