An unauthorized hiker in a restricted zone venturing out onto an unstable sea cliff over a lava tube where hot lava from the 61G flow from Kilauea Volcano enters the ocean from the open end of a lava tube, just as a violent steam explosion throws hot pumice rocks back onto the sea cliff, at the Kamokuna entry in Hawaii Volcanoes National Park, Puna, Hawaii. January 2017.
