Map with thermal overlay showing active flows

December 30, 2015
This map overlays a georeferenced thermal image mosaic onto a map of the flow field near Pu‘u ‘Ō‘ō; to show the distribution of active and recently active breakouts. The thermal images were collected during a helicopter overflight on December 30. The June 27th flow is outlined in green to highlight the previously mapped flow margin. The yellow lines show the active lava tube system, as currently mapped. Pu‘u ‘Ō‘ō is at lower left.
