USGS webcam--F1cam

Color thermal images of lava lake

Detailed Description

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 image on the right was taken today at 8:22 a.m. HST, December 22. The water lake had been replaced by a lake of lava that was fed by multiple fissure that opened on the Halema‘uma‘u crater wall. Note the difference in temperature scales (degrees Celsius) between the two images.
