I see that Halemaumau in Hawaii is erupting again. Post from a well known local Ikaika Marzo who was sharing many photos last time.

https://volcanoes.usgs.gov/hans2/index/ ... 5:37-08:00Shortly after approximately 9:30 p.m. HST, the USGS Hawaiian Volcano Observatory (HVO) detected glow within Halemaʻumaʻu crater at the summit of Kīlauea Volcano. An eruption has commenced within Kīlauea’s summit caldera. The situation is rapidly evolving and HVO will issue another statement when more information is available.

Update On New Kilauea Eruption (Dec. 21, 2020)
https://www.youtube.com/watch?v=oYy5-FeG53c
Video 4:48Scientists and emergency officials said on Monday morning that the new eruption at the summit of Kilauea has stabilized. The Volcano Alert Level was lowered from Warning to Watch, and the Aviation Color Code from Red to Orange, reflecting the less-hazardous nature of the ongoing eruption. ...

Kīlauea starts new eruptive cycle with a lava show

Kīlauea Volcano on the Big Island of Hawaii reawakened on Dec. 20 with a flourish, fountaining lava in its summit crater. Temblor talks with volcanologist Michael Poland about what the eruption means.
At 9:30 p.m. local time on Dec. 20, Kīlauea Volcano erupted for the first time since 2018. After seismicity ramped up about starting at approximately 8:30 p.m., lava broke out of the walls of Kīlauea’s summit crater, Halema’uma’u. The fresh lava vaporized the crater’s water lake, swapping it for a new lava lake on the crater floor. Fountains initially flowed out of three vents in the crater wall, filling the crater at a rate of several meters per hour. Don’t worry: Rates have slowed to about 1 meter, or approximately 3 feet, per hour and as of the morning of Dec. 22, the lava lake was still more than 480 meters, or approximately 1,600 feet below the crater rim. And even if the lava lake does eventually overflow, it will flow onto the summit caldera floor.
The volcano’s last eruption ended in 2018, after consistently erupting for 35 years. While much of that lengthy eruption had been fairly safe, with effusive lava flows at the ocean front and bubbling lava lakes in the Pu’u ‘Ō’ō cone and the summit, the increased activity in 2018 spectacularly disrupted life on the Big Island. From May through August 2018, Kīlauea erupted as much lava as it normally produces in 10 to 20 years. It opened up a couple of dozen new fissures, shot lava fountains more than 80 meters (260 feet) into the air, buried roads and destroyed some 700 homes. Then, it stopped.
At the end of the 2018 eruption, scientists thought that the magma reservoir that had been feeding the eruption had emptied like a deflated balloon, explaining why the eruption stopped. “We had speculated that the volume of magma that was in that reservoir was actually about what was erupted,” says volcanologist Michael Poland of the U.S. Geological Survey. But subsequent studies have suggested the massive eruption actually only drained a small fraction of the total volume of the reservoir, he says.
Kīlauea is one of the most active volcanoes on Earth and also one of the best instrumented. As such, scientists — and the world, thanks to the Hawaiian Volcano Observatory webcams — can see what’s happening at the volcano in real time.
Article continues Q & A style, I consider it worth a gander.

https://www.usgs.gov/volcanoes/kilauea/ ... anoes-fy23Kīlauea volcano is erupting. At approximately 3:15 p.m. HST on September 10, 2023, the USGS Hawaiian Volcano Observatory observed eruptive activity in Kīlauea summit webcam images and from field reports indicating that an eruption has commenced within Halemaʻumaʻu crater and on the down dropped block to the east in Kīlauea’s summit caldera, within Hawai‘i Volcanoes National Park.
