Episode 13 fountaining at Kīlauea summit

During a March 11 Hawaiian Volcano Observatory eruption monitoring flight at Kīlauea summit, scientists landed to make observations and collect samples. At the front of the channelized flow from the episode 13 north vent fountain in Halema‘uma‘u crater, a USGS geologist walks the flow margin to find a safe spot to collect a molten lava sample. All samples are collected in coordination with, and after receiving permission from, Hawai‘i Volcanoes National Park. Analysis of the sample will provide information for ongoing eruption hazard assessment. USGS photo by M. Patrick.
