Volcano Awareness Month hikes continue with USGS Volcanoes!
USGS Hawaiian Volcano Observatory geologist Dr. Carolyn Parcheta leads this two-hour guided walk along the fissure that started the Mauna Ulu eruption on May 24, 1969. Lava continued to erupt over the next five years, making it the longest observed effusive rift eruption at the time. The eruption ultimately built
a lava shield, Mauna Ulu (“growing mountain”), a prominent landmark on Kīlauea’s East Rift Zone. It also sent lava flows to the coast and allowed for detailed observations of eruption processes. During the walk, Carolyn describes how fissures form, how lava fountains erupt, how these eruptions create the environment you see, and why some lava drained back into the ground. She also discusses her research that revealed just how deep the fissure extends into the ground. A park ranger assists to answer questions about Hawaiʻi Volcanoes National Park. Free (park entrance fees apply).
