Kīlauea's Pu‘u ‘Ō‘ō lava flow advances toward the ocean

Detailed Description
As Kīlauea Volcano's active pāhoehoe flow spreads across the coastal plain on July 6, the new lava appeared more shiny or silvery compared with the older lava beneath it. Molten "toes" of lava breaking out from the leading edges of the flow can be seen in the lower right quadrant of the photo. USGS photo.
