Video from live stream camera captures collapse event at Kīlauea's summit

The summit caldera of Kīlauea underwent a collapse event on July 24, 2018, at 6:41 AM HST, with an estimated magnitude of 5.3. This event was similar in character and magnitude to previous collapse events. Watch as the event unfolds in this video from the live stream camera: (1) at the time stamp of 6:41:08 (upper left), a small tree along the right margin of the video begins to sway; (2) at 6:41:10, a pressure wave passes through the steam plume in the crater, and light is reflected back to the camera (this reflection highlights the passage of the expanding sound energy through the air); (3) at 6:41:11 rockfall begins on the south Sulphur Banks (distant scarp on left).
