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 (

When Matt measured the lava lake level this morning, the lake surface was 89 feet (27 m) below the Overlook crater rim. With the lava lake at that level, spattering on the lake surface could be seen from the Jaggar Museum overlook in Hawai‘i Volcanoes National Park today.

Matt Patrick on Kīlauea

For the 10th anniversary of Kīlauea Volcano's summit eruption, USGS–Hawaiian Volcano Observatory research geologist Matt Patrick talks about his work monitoring the lava lake in the Halema'uma'u Crater. Dr. Patrick describes the explosion that created the lava lake in 2008 and points out features of the lake including the moving crustal plates, gas bursts, spatter, and collapse scars on the crater rim. Dr. Patrick also discusses hazards near the lake, such as explosions of gas and spatter, and volcanic gases, and the types of protective clothing worn by scientists who enter the closed area near the lake to collect daily lake level measurements.
