Thermal time-lapse imagery of advancing 'a'a lava in the Valle del Bove. The flow fronts are fed by lava channels that descend the headwall of the valley (top of the frame). As the clip progresses, a pulse of lava is seen descending the channels and overflowing the levees. Black = cold, warmer colours show hotter areas of the active flow.
