Spattering is common in Kīlauea Volcano's summit lava lake, and consists of many large bursting gas bubbles. The fluid nature of the lake can be seen when lava hits the wall and flows downward like syrup. The thin, flexible nature of the crust is also shown here, as the bursting gas bubbles rip and fold the thin skin on the lake. This video was taken from the rim of Halema‘uma‘u, an area that remains closed to the public due to ongoing volcanic hazards.
