3D Imaging Reveals Details of Volcanic Flows

Not exactly volcano-lancing, but it’s a start:

To collect the data, researchers equip airplanes with hundreds of thousands of lasers that scan the terrain at a perpendicular angle to the ground. The lengths of the laser beams indicate the height of the flow, and when multiplied hundreds of thousands of times, the scans can be compiled into 3D models that recreate the internal structure of the flow.
