HVO field crews observed activity within Halema‘uma‘u, at Kīlauea Volcano's summit, overnight from within a closed area of Hawai‘i Volcanoes National Park. The area remains closed to the public for safety reasons and HVO field crews are equipped with a range of specialized safety gear and personal protective equipment.

This photo, taken at approximately 5:30 a.m. December 29, 2020, shows Kīlauea's ongoing summit eruption. The western vent in the wall of Halema‘uma‘u continued to erupt overnight, and the northern/eastern vent remained inactive. At approximately 3:45 a.m. HST today (Dec.

HVO scientists monitor the ongoing Kīlauea summit eruption from within an area of Hawai‘i Volcanoes National Park that remains closed to the public for safety reasons. They are equipped with a range of specialized safety gear and personal protective equipment such as gas masks, helmets, gloves, and eye protection.

This graphic depicts the changes to Kīlauea Volcano's summit resulting from the eruption that began on December 20, 2020. Pre-eruption topography of Halema'uma'u crater, collected in 2019, is shown on the left and compared to the topography at the summit on December 26, 2020.

Portions of Crater Rim Drive that down-dropped during Kīlauea's 2018 collapse events, are visible in the lower left. This area remains closed to the public due to hazardous conditions.

A helicopter overflight yesterday (Dec. 28, 2020) at approximately 10:30 AM HST allowed for aerial visual and thermal imagery to be collected of the new eruption within Halema'uma'u crater at the summit of Kīlauea Volcano. This preliminary thermal map shows that the lake area has not changed significantly since the thermal map that was made on December 26.

HVO scientists use a laser rangefinder to measure the distance to the lava lake surface at Kīlauea's summit.

HVO field crews observed the continuing eruption in Halema‘uma‘u at Kīlauea's summit early this morning. Overnight, the western vent in the wall of Halema‘uma‘u continued to erupt, and the northern/eastern vent remained inactive. At approximately 4:30 a.m. HST today (Dec. 28), HVO field crews measured the lava lake as 179 m (586 ft) deep.

The eruption with Halema‘uma‘u continues on the evening of December 28, 2020. This photo shows an HVO scientist making observations of Kīlauea's summit lava lake, with Mauna Loa in the background. HVO scientists have been monitoring the eruption from within an area of Hawai‘i Volcanoes National Park that remains closed to the public for safety reasons.
