Hawaiian volcanoes typically evolve in four stages as volcanism waxes and wanes: (1) early alkalic, when volcanism originates on the deep sea floor; (2) shield, when roughly 95 percent of a volcano's volume is emplaced; (3) post-shield alkalic, when small-volume eruptions build …Volcano Activity Updates Kīlauea is not erupting. Its USGS Volcano Alert level is ADVISORY. Webcams show no signs of active lava in Halemaʻumaʻu crater, at the summit of Kīlauea in Hawai‘i Volcanoes National Park. Over the past week, summit tiltmeters showed inflation and seismicity remains elevated beneath Kīlauea summit and …The Hawaiian Volcano Observatory (HVO) is part of the U.S. Geological Survey's Volcano Hazards Program. Founded in 1912 by Thomas A. Jaggar, HVO was the first of the five volcano observatories supported by USGS today. HVO's methods of observing and analyzing data from instruments and field studies have changed dramatically since Jaggar's time. Medicine Lake caldera viewed from the south rim facing north.
