Timelapse videos are cool, and especially when they’re of volcanic activity.
The video below shows timelapse footage captured on the Halema‘uma‘u crater at the summit of Kīlauea, an active shield volcano located on Hawaii’s Big Island. It stands at 4,091 feet above sea level.
USGS: “This timelapse sequence shows activity in Halema‘uma‘u, at the summit of Kīlauea, from March to August. The video shows the rise of the crater floor due to lava supplied beneath the surface crust, lifting the crater floor in an “endogenous” process. In addition, lava flows erupt sporadically and resurface portions of the crater floor.”
