#Eruption

After nearly 10 hours, Episode 40 of the Halemaʻumaʻu eruption comes to a sudden end.

Often spotted by onlookers in Hawaiʻi Volcanoes National Park, or even by YouTube livestream viewers, the long, ashy gray or brown, ropy cloud-like structures tend to appear near or downwind of active lava fountains.

Scientists at the Hawaiian Volcano Observatory, in collaboration with the U.S. Geological Survey, have installed a new livestream monitoring camera at Kīlauea on the Big Island.

At 10 a.m., livestream cameras from the U.S. Geological Survey showed smoke billowing out of the Halema‘uma‘u Crater.

Models forecast an eruption window for Nov. 4–8, with Nov. 5-7 most probable.

The $25.6 million initiative, called Sage Grande, is being led by the National Science Foundation. As part of the work, experts will be placing 300 advanced sensor systems in locations across the country to monitor the environment and provide faster warnings for natural disasters such as wildfires, floods, and volcanic eruptions.

As of this morning, Halemaʻumaʻu continues to be quiet with passive outgassing plumes rising from the north and south vents.

High lava fountains fired off for 8 of the continous 9 hours of fountaining during the latest eruptive episode of the Big Island’s Kīlauea volcano until ending abruptly at 1:20 p.m. July 9.

Hawaiʻi Volcanoes National Park reports heavy traffic on Highway 11 between Puna and Kāʻu due to the current Halemaʻumaʻu eruption.

Recently, something has been observed “dancing” above the active eruptive vents inside Halemaʻumaʻu…Hydrogen flames!

As enthralling as each eruptive episode is, experts at the USGS Hawaiian Volcano Observatory watch just as closely at what’s happening between episodes.

Work on the Hawaiian Volcano Observatoryʻs new permanent home and a field station continue despite a recent scare, when its temporary home in Hilo was on the original list of federal buildings “not core to government operations,” according to the Trump Administration.

It took about 10 hours or so, but the vents inside Halemaʻumaʻu Crater within Hawai’i Volcanoes National Park once again did not disappoint, but officials warn there are some hazards to watch out for accompanying the roaring geysers of molten rock.

It was a dark and stormy night when the eruption near Nāpau Crater on Kīlauea’s East Rift Zone began Sept. 15, 2024. So much so that Hawaiian Volcano Observatory webcams were no help in detecting if there was an eruption or not. But you know who could? Residents of Volcano, who could smell sulfurous and burning odors.

The latest eruptive activity started at 8:22 p.m. Feb. 19 and ended at 9:18 a.m. Feb. 20. Lava flows from this episode covered 73% of the Halemaʻumaʻu Crater floor in the southern part of Kaluapele, the volcano’s caldera.

Episode 9 of the Big Island volcano’s ongoing summit eruption in Halemaʻumaʻu Crater began at 10:16 a.m. Tuesday. Lava flowing into the crater from the north vent covered about a quarter of the crater floor by 10:45 a.m. Slow effusion of lava also started at about 10:50 a.m. from the south vent.

Kīlauea volcano’s Episode 7 of eruptive activity ends abrubtly 16 hours after it began, but inflation at the summit is already on the rise again, so it might not be long until an Episode 8 is underway.

Hawaiian Volcano Observatory said based on the durations of Episodes 5 and 6, and the short pauses that separated them, this episode of eruptive activity in the Big Island volcano’s caldera will likely last 10 to 20 hours.

Hawaiian Volcano Observatory says another eruptive event could start within the next 1 to 2 days if the inflation rate at the Big Island volcano’s summit stays similar to that during Episode 5. The tiltmeter at Uēkahuna bluff started recording the start of inflationary tilt at 1 p.m. Jan. 25.

Episode 6 of the Big Island volcano’s latest eruption, which began the week of Christmas 2024, is underway as lava flows onto the crater floor from a geiser that started at about 11:28 p.m. Jan. 24.
