Large-scale map of flow field

This map shows recent changes to Kīlauea's active East Rift Zone lava flow field. The area of the flow field on January 5 is shown in pink, while widening and advancement of the flow field as mapped on January 19 is shown in red. The yellow lines show the active lava tube system. Pu‘u ‘Ō‘ō lava flows erupted prior to June 27, 2014, are shown in gray.
