Large-scale map with thermal overlay showing active flows

This map overlays a georeferenced thermal image mosaic onto the current 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 March 25. The June 27th flow field as of March 25 is outlined in green for comparison. The yellow lines show the active lava tube system, as currently mapped. Pu‘u ‘Ō‘ō is at lower left.
