January 15, 2013 - "Volcano Awareness Month: What's Happening in Halema'uma'u Crater?"
In March 2008, a new volcanic vent opened in 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 has now grown to more than 520 feet wide. 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 will present an overview of Kīlauea's summit eruption, including a survey of the volcanic processes occurring within the vent.
