This video, taken during an early morning overflight on 30 November 2022, shows fissure 3, the dominant source of activity. The lava fountains are 20-25 meters in height (65-82 feet) and are feeding a lava flow that is moving to the northeast at ~130 meters per hour (0.08 miles per hour).

An ‘a‘ā lava flow on the northeast flank of Mauna Loa. This lava flow is several meters thick and moving to the northeast. 'A'ā flows have a rough rubbly surface composed of broken lava blocks called clinkers. The clinkery surface covers a massive dense core, which is the most active part of the flow.

A routine helicopter overflight of the summit of Kīlauea provided airborne views of the lava within Halema‘uma‘u crater. The active lava lake is limited to the western portion of the crater floor, near the main source of white fume. The remainder of the crater floor consists of solidified lava flows.

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.
