July 5, 2018, collapse event at Kīlauea Volcano's summit

Since August 4, 2018, Kīlauea Volcano's summit activity has diminished dramatically. But between mid-May and early August, 62 collapse events occurred, with each releasing energy equivalent to a magnitude-5+ earthquake and causing extensive ground shaking in the summit area. On July 5, 2018, USGS video cameras stationed at various summit locations happened to record one of the collapse events. The first clip shows the USGS Hawaiian Volcano Observatory entrance sign rattling in response to ground shaking. The second clip shows dramatic movement along the rock wall and a ground crack at the Jaggar Museum Overlook in Hawai‘i Volcanoes National Park—visual reminders of hazards associated with the collapses. Most of the audio is wind noise, but the sound of rocks falling from steep crater walls within Halema‘uma‘u can also be heard as dust rises from the Kīlauea caldera.
