Episode 53 of the ongoing Halemaʻumaʻu eruption ended at 1:23 a.m. HST on August 13 after 9.6 hours of continuous lava fountaining.
Kilauea Message 2026-08-13 01:03:17 HST
The north vent fountain has dropped to 150-200 feet (50-60 meters) high. Tremor is also dropping. Deflation measured on the UWD tiltmeter is 13.7 microradians.
Kilauea Message 2026-08-12 23:39:19 HST
The north vent fountain is now about 300 feet (90 meters) high and feeds lava flows that cover about 40-50% of the floor of Halemaʻumaʻu crater. Currently the plume cloud is at about 11000 feet (3400 meters) ASL.
Kilauea Message 2026-08-12 21:51:40 HST
The north vent fountain is now about 330 feet (100 meters) high. The plume cloud is now about 10,000 feet (3,000 meters) ASL. Associated lava flows have covered about 30-40% of the crater floor at this time.
Kilauea Message 2026-08-12 20:30:31 HST
The north vent fountain remains about 350-400 feet (110-120 meters) high. The plume cloud has dropped to about 14000 feet ASL. Associated lava flows have covered about 30-40% of the crater floor at this time.
Kilauea Message 2026-08-12 18:42:59 HST
The north vent fountain has dropped to just over 350 feet (110 meters) high. The volcanic plume is blowing due west over the summit of Mauna Loa. Lava flows have covered about one third of the floor of Halemaʻumaʻu crater.

North vent fountain peaking at 500 feet (150 meters) and producing moderate tephra and gas. Plume is over 18000 feet (5600 meters) ASL with a low level layer of gas and tephra moving southwest and a higher level moving more westerly.
Kilauea Message 2026-08-12 16:38:00 HST
North vent fountain is about 400 feet (120 meters) high. The plume cloud is approximately 16000 feet (5000 meters) high at this time.
Kilauea Message 2026-08-12 16:15:42 HST
North vent fountain is currently over 250 feet (75 meters) high and growing. Overflows continue from the collapse pit into the south vent and off to the south of the pit. The top of the plume cloud is currently 12000 ft (3700 meters) ASL.
Kilauea Message 2026-08-12 16:04:29 HST
Fountains are expected to reach peak heights in 1-2 hours. Lower level winds will carry tephra and gas to the southwest, while higher level winds will carry tephra and gas westward. Impact on communities should be limited.
