Kīlauea summit eruption—October 12, 2021
Kīlauea summit eruption—October 12, 2021
Kīlauea summit eruption—October 12, 2021

The eruption continues within Halema‘uma‘u crater, at the summit of Kīlauea. The western vent supplies lava into the lava lake through a short spillway. Consistent fountain heights of 10–15 meters (30–50 ft) were interrupted by frequent larger busts of spatter exceeding the height of the cone (30 m or 100 ft).

Kīlauea summit eruption lava fountain height in Halema‘uma‘u crater on October 10, 2021 was highly variable. A persistent low fountain a few meters (yards) tall was frequently interrupted by larger series of bursts throwing lava more than 15 meters (50 feet) into the air and onto the interior walls of the vent cone.

The eruption continues in Halema‘uma‘u crater, at the summit of Kīlauea. Lava fountaining no longer emerges from the central portion of the lake, with fountaining limited to the west vent shown here. Low fountaining within the cone supplies lava into the lake via a short spillway.

An eruption in Halema‘uma‘u crater, at the summit of Kīlauea, began yesterday afternoon and continues this morning. During an overflight at approximately 7:30 a.m. HST on September 30, 2021, several fountaining sources were active in the crater, including those in the lake center and on the west wall.

Lava fountains through the lava lake in Halema‘uma‘u, at Kīlauea's summit, create waves or ripples in the lake surface. The ripples are visible on the surface as thin crustal plates move apart and back together again as the wave motion passes by (like inner tubes in a crowded wave pool), creating a moving arc of increased glow.

We sometimes fall back on an implicit model that post-wildfire debris flows are only triggered once a certain level of saturation or rainfall is reached, and that the sediment supply is soon exhausted and future flows are unlikely until it recharges.
