Happenings in Halema‘uma‘u: An update on Kīlauea's summit eruption
In March 2008, a new volcanic vent opened within Halema'uma'u Crater at the summit of Kīlauea. Since then, the eruption has consisted of continuous degassing, occasional explosive events, and fluctuating lava lake activity in an open crater that is now 520 ft by 690 ft in size. While thousands of visitors flock to see the nighttime glow emitted by the lava lake, Kīlauea's summit eruption also provides an abundance of data and insights for scientists. USGS Hawaiian Volcano Observatory geologist Matt Patrick presents an update on Kīlauea's summit eruption, including an overview of the volcanic processes occurring within the vent.
