Aerial view of the fissure 8 lava channel on KÄ«lauea Volcano’s lower East Rift Zone in the vicinity of the Kapoho cone, with fissure 8 fountains visible in the distance (upper left). Helicopter overflights of the eruption site are routinely scheduled to check for any new outbreaks of lava and to collect GPS data on the active flow—information that’s needed to make the flow field maps that are posted on HVO’s website (https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_maps.html).
