View of fissure 3 erupting on the Northeast Rift Zone of Mauna Loa the morning of December 4, 2022. Lava fountaining at the vent was approximately 100 feet (33 m) tall yesterday; fragments of lava are deposited in the area near the vent construct the cone visible in this video. USGS video by F. Trusdell.

Two decades of drought are contributing to low water levels in reservoirs along the Colorado River, including Lake Powell.
Lake Powell’s highest recorded water level was in 1983. In this 1984 Landsat 5 image, the lake’s elevation was 3,702 feet above sea level.

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.
