Lava Flow

Movement of the southern lava flow was successfully detected from a variety of viewpoints. The topography and reflection data shown below was taken from a range of 4km the furthest range to natural terrain imaged to date.

Subsequent days surface topography could then be subtracted to produce a measurement of total volume change and hence the rate of lava flow. The image below shows the ‘top down’ views of surface height change between different days.
