The summit area has two flat-topped mesas, whose smooth tops give a relatively dark appearance in the radar image.

The colours in a radar image normally range from blue or green for weak returns, to red or magenta for very strong returns.

Video providing a radar image of the target would be transmitted back to the bomber.

The dark flows on the lower right of the radar image are thought to be smoother than the brighter ones near the central part of the volcano.
