A comparison of two thermal images from the F1cam thermal webcam located on the rim of Halema‘uma‘u crater, at the summit of Kīlauea volcano. These two images were taken 48 hours apart. The left image from December 20 at 8:22 a.m. HST, shows the water lake that was in the bottom of the crater—approximately 13 hours before the start of the summit eruption at Kīlauea. The

This comparison shows thermal images taken yesterday and today during USGS Hawaiian Volcano Observatory helicopter overflights. The main difference in this 24 hour period is the significant rise and infilling of the lava lake within Halema‘uma‘u crater at Kīlauea summit. This morning, the lake depth was measured at approximately 130 yards. USGS images by M. Patrick. 

The recent eruption at Kīlauea Volcano's summit, within Halema‘uma‘u crater, has generated a lava lake that is being fed by two fissures. Halema‘uma‘u crater has previously been occupied by a water lake (July 2019 to December 2020) and a lava lake (2008 to 2018). The current lava lake is larger than both previous lakes; though it occupies a similar (but larger) location of

Aerial imagery collected during a USGS Hawaiian Volcano Observatory overflight at approximately 11:35 a.m. HST. This photo shows the two active fissures in Kīlauea Volcano's ongoing summit eruption in Halema‘uma‘u crater. These fissures in the wall of Halema‘uma‘u crater feed a growing lake at its base. In the center of the lake, an island rises approximately 17 m (55 ft)

Aerial visual imagery collected during an overflight of Kīlauea Volcano's summit just after 11 a.m. HST on December 21, 2020, was used to create a preliminary topographic model. When compared to pre-eruption topographic models, it shows that the bottom of Halema'uma'u crater has been filled by over 100 m (yd) of lava. Map by B. Carr.

On the morning of Dec. 21, Hawaiian Volcano Observatory gas scientists use a FTIR spectrometer on the rim of Halema‘uma‘u crater. The FTIR measures the composition of the gases being emitted during Kīlauea Volcano's ongoing summit eruption by measuring how the plume absorbs infrared energy. The plume being generated by the ongoing eruption is sulfur-dioxide (SO2) rich, but

A helicopter overflight today (Dec 21, 2020) at approximately ~11:30 AM HST allowed for aerial visual and thermal imagery to be collected of the new eruption within Halema'uma'ucrater at the summit of Kīlauea Volcano. This preliminary thermal map shows that the new lava lake is 580 m (yd) E-W axis and 320 m (yd) in N-S axis. The lake area is about 13.6 hectares (33 acres

Hawaiian Volcano Observatory field crews captured this photo of the thick gas plume, produced by the Kīlauea summit eruption, obscuring the intensity of the sun. Crater Rim Drive (a closed region of Hawaii Volcanoes National Park) is covered in a layer of tephra—volcanic glass—which has been transported by trade winds in the eruption plume, blanketing the pavement below.

HVO geologist retrieves and labels tephra samples from collection buckets placed downwind of Halema‘uma‘u crater after the onset of the Kīlauea summit eruption. These samples are collected for petrological analysis to gain further insight into the eruption dynamics.

Aerial view of the Kīlauea summit eruption from a Hawaiian Volcano Observatory overflight at approximately 11:20 a.m. HST. The two active fissure locations continue to feed lava into the growing lava lake in Halema‘uma‘u crater, with the northern fissure (pictured right) remaining dominant.

Concentrations in drinking-water wells that exceeded the health-based screening level of 4,000 micrograms per liter largely occurred in carbonate-rock aquifers, particularly in southern Florida and central Texas, and in areas where upwelling brines mix with potable

Kīlauea summit KW webcam image taken on December 20, 2020, just before 6 p.m. HST. Three and a half hours later, at 9:30 p.m., an eruption began in the walls of Halemaʻumaʻu crater, vaporizing the lake. You can view live KW webcam images here. USGS photo. 

Shortly after approximately 9:30 p.m. HST, an eruption commenced at the summit of Kīlauea Volcano. Red spots are the approximate locations of fissure vents feeding lava flowing into the bottom of Halema‘uma‘u crater. The water lake at the base of Halema‘uma‘u crater has been replaced with a growing lava lake. Lava coverage is deeper by 10 m (32 ft) or larger and bigger in

The black oystercatcher, a keystone species in nearshore ecosystems, plays an important role in structuring nearshore systems and is highly susceptible to human disturbance. Current inventory and monitoring efforts may not adequately address the information needs for estimating long-term trends for this species. To address these issues, the goal of this research is to

The U.S. Geological Survey is conducting research to guide the recovery of the threatened Elkhorn coral, Acropora palmata, in Dry Tortugas National Park and throughout the western Atlantic. A small Elkhorn colony, raised from a fragment collected after a storm, is shown here in the foreground after it was cemented to the reef to establish a new coral population.

Examining environmental deoxyribonucleic acid (eDNA) in water samples has demonstrated promise for identifying fish species present in water bodies. However, whether or not this same approach can be used to assess relative abundance, biomass, and species composition in large (greater than [>] 200-hectare) waterbodies is unclear.
