USGS webcam--F1cam
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
...Kīlauea summit eruption thermal image comparison
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.
December 21, 2020—Kīlauea summit eruption reference map
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

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.
Scientists use a FTIR spectrometer
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
