A new eruption began within Halema‘uma‘u crater, at the summit of Kīlauea just after 4:30 p.m. HST on January 5, 2023. Around 5:45 p.m. on the same day, an additional vent began erupting lava on the floor of the crater. The newer vent is located farther away in this image. USGS image by D. Downs.

This video, captured by the KWcam, shows a large burst of lava from the newly opened vent in Halema‘uma‘u crater, Kīlauea volcano at approximately 4:49 pm HST on January 5, 2023. This burst reached up to 50 meters (164 feet) high and sent a wave of lava across the crater floor.

The KWcam webcam, on the west rim of Kīlauea caldera, was upgraded on January 4, 2023, to a more advanced model, which provides a slightly wider view and higher image quality. This should provide an improved view of any future activity in Halema‘uma‘u. In this photo, an HVO scientist begins the process of the webcam swap. USGS photo by M. Patrick.

A tumbleweed of Pele’s hairs—collected near Saddle Road on November 29, 2022—viewed under a microscope. The scale bar in the lower right is 750 micrometers (0.03 inches) wide. The golden-brown glass strands are intertwined, whereas the thicker dark glass is rigid. The shape of the darker glass reflects the shape of the lava droplets as they quenched.

A tripod on Mauna Loa's summit and holding a GPS antenna for the Hawaiian Volcano Observatory's post-eruption survey of Mauna Loa was iced in during the recent Kona low storm. The ice broke away easily and there was no damage to the equipment.

Hawaiian Volcano Observatory geophysicist Ingrid Johanson checks on a survey-mode GPS instrument deployed near the summit of Mauna Loa. This survey will supplement HVO's network of continuous GPS instruments and provide higher spatial density of measurements for how Mauna Loa deformed during the recent eruption.

January 2023 is the Island of Hawaiʻi's 14^th annual Volcano Awareness Month. Presentations about Hawaiian volcanoes will be offered around the Island of Hawaiʻi throughout January 2023. 

As of 7:00 a.m. on December 12, Hawaiian Volcano Observatory geologists observed only residual incandescence and no lava movement in the fissure 3 vent on the Northeast Rift Zone of Mauna Loa. The channels below the vent appear drained of lava and no longer feed the main flow front. USGS image by F. Trusdell. 

The Northeast Rift Zone eruption of Mauna Loa that began the evening of November 27, 2022, continues at greatly reduced levels as of December 12, 2022 (fifteenth full day). Only incandescence was observed within fissure 3 overnight. This morning, field crews heard small explosions accompanied by sprays of spatter from the west end of the fissure 3 vent.

Geologists conducted a monitoring overflight of Kīlauea summit on the morning of December 10, 2022. They noted that the lava lake within Halemaʻumaʻu crater was mostly solidified, though incandescence was visible. USGS image by J. Bard.

Just days, ago, lava was full in the channels from the fissure 3 eruption on Mauna Loa's Northeast Rift Zone. Over the past two days, the eruption output has greatly reduced. A pond of lava in the fissure 3 cone feeds short lava flows that extended only 1.6 mi (2.6 km) from the vent.
