The active pāhoehoe flows of Pu‘u ‘Ō‘ō

Detailed Description

This thermal image, looking northwest, shows the active flows east of Pu‘u ‘Ō‘ō. Bright yellow portions of the image represent areas of active lava. A short channelized flow was active on the upper east flank of the cone, with most activity— comprising pāhoehoe (center of image)—heading southeast. These pāhoehoe flows had reached about 2.6 kilometers (1.6 miles) from the vent during today's overflight.
