HVO Happenings

Upcoming HVO talk

Runt of the litter: The 1924 explosive eruption of Kīlauea
The 1924 explosive eruption of Kīlauea, May 22, 1924Of all the early (pre-1924) explosive eruptions of Kīlauea, the May 1924 event was the smallest—the runt of the litter. On the 90th anniversary of the eruption, you are invited to join HVO geologist Don Swanson and volunteer Ben Gaddis as they talk about what happened in 1924, what caused the explosive eruption, and more, in this "After Dark in the Park" program in the Hawaiʻi Volcanoes National Park Kīlauea Visitor Center at 7:00 p.m. on May 13.

Recent HVO general interest publication

The first five years of Kīlauea's summit eruption in Halemaʻumaʻu Crater, 2008-2013 Halemaʻumaʻu October 2012
… From the time the eruption began, the new "Overlook crater" inside Halemaʻumaʻu has exhibited fluctuating lava lake activity, occasional small explosive events, and a persistent gas plume. The beautiful nighttime glow impresses and thrills visitors in Hawaiʻi Volcanoes National Park, but the continuous emission of sulfur dioxide gas produces "vog" (volcanic smog) that can severely affect communities and local agriculture downwind. …

Recent HVO research paper

Continuous monitoring of Hawaiian volcanoes with thermal cameras Halemaʻumaʻu October 2012
… Thermal cameras can sometimes "see" through volcanic fume that obscures views to visual webcams and the naked eye, and often provide a much clearer view of the extent of high temperature areas and activity levels. We describe a thermal camera network recently installed by the Hawaiian Volcano Observatory to monitor Kīlauea's summit and east rift zone eruptions (at Halemaʻumaʻu and Puʻu ʻŌʻō craters, respectively) and to keep watch on Mauna Loa's summit caldera. … See paper for more info.
