Lava flows, Kilauea volcano, Hawaii

The island of Hawaii (the "Big Island") is the location of the currently active volcanoes, Mauna Loa and Kilauea.The Hawaiian lavas are of two distinct forms, although chemically they are the same: *a'a* (viscous, rough) and *Pahoehoe* (smooth, ropy, billowy). This image is a close-up of solidified *pahoehoe* taken from along the Chain of Craters road which leads from Kilauea crater to the south-eastern Puna coast of the island where the lava flows enter the sea.
