Kīlauea Eruption Update: More Fluctuations & Another Short Pause

3:03 AM · Dec 17, 2021

A one-day pause ending on December 14, 2021 appears to be the fifth such lull, and the second in two weeks in Kīlauea's eruption, now ongoing for two-and-a-half months. Fluctuations in lava output continue to be evident in our time-lapse compilations since the short pause, and are matched by similar variations in ground tilt and gas output. Maunaloa monitoring signals emerge from their flatline but still only indicate minor changes, with no need for additional concern. We review these changes as documented by webcams, monitoring signals and reports courtesy of the USGS Hawaiian Volcano Observatory. As usual we visually annotate the scientific processes and discuss live viewer questions as we go. The eruption still poses no direct threat to people apart from its gas and particulates, shifting our focus to the observed processes and their context in volcano science. Epic views from the public overlook within Hawaiʻi Volcanoes National Park document the changes, with every visitor experiencing a unique moment in its evolution.
