A helicopter overflight this afternoon (April 23) of Kīlauea Volcano's Halema‘uma‘u crater showed the extent of the largest overflow (silver gray) of the lava lake from approximately 6:30-9:30 a.m. this morning. The overflow covered much of the April/May 2015 and October 2016 overflows, but a section of the 2015 overflow is visible on the south (upper edge) of Halema‘uma‘u crater floor. At the time of the flight, multiple spattering sites were active around the margin of the lava lake, and the lake surface was a few meters (yards) below the rim.
