The June 27 Kīlauea volcano lava flow remains active. A Civil Defense overflight this morning observed that the flow continues heading in a northeast direction through thick forest in the northwest portion of Kaohe Homesteads. For the most up to date information, visit the Hawaiian Volcano Observatory website. hvo.wr.usgs.gov/ Video from September 15, 2014 shows a view through a skylight on the June 27 lava tube, which provided a clear view of the flowing lava stream. HVO geologists calculated the volume of lava flowing through the tube by using two measurements. First, a transect of very-low-frequency (VLF) measurements across the roof of the tube was used to measure the cross-sectional area of lava flowing through the tube. Second, a radar gun was used to measure the speed that lava is flowing at that location. The September 15 measurement showed a flow rate of 5.8 cubic meters per second (roughly 1500 gallons per second). Tracking the lava supply rate like this can be helpful for anticipating fluctuations in activity at the flow front. #hvo #hawaiianvolcanoobservatory #lava #lavaflow #volcanoes #kilauea #volcanohazards #volcanohazardsprogram #naturalhazards #usgs
