USGS Scienctist talks about his work monitoring the lava lake

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.
