10th anniversary of Kīlauea volcano's summit eruption

Today marks the 10th anniversary of the eruption within Halema‘uma‘u at the summit of Kīlauea Volcano. When the vent first opened on March 19, 2008, it formed a small pit about 115 feet (35 m) wide. Over the past decade, that pit (informally called the "Overlook crater") has grown into a gaping hole about 919 feet by 656 feet (280 x 200 m) in size. Click on the above webcam images to watch the growth of Overlook crater over the past 10 years. This video clip is from "Kīlauea Summit Eruption—Lava Returns to Halema‘uma‘u," a 24-minute USGS video that tells the story of this ongoing eruption. It can be viewed on the USGS YouTube Channel (
