An explosion where a lava flow from Kilauea Volcano hit the ocean at Waikupanaha at dusk Sunday entertained visitors who hiked out to a viewing area set up by Hawaii County. These littoral explosions, as scientists at the U.S. Geological Survey call them, have been common throughout the last several weeks at ocean-entry site. The viewing site is off Highway 130 and is open from 2 p.m. to 10 p.m. daily. Be prepared to hike about a mile on uneven lava fields.
