Halema'uma'u Lava Lake Double Rainbow

9:53 PM · Feb 23, 2021

One strong rainbow, and one faint rainbow inside Halema'uma'u. "A pot of lava at the end of the rainbow? A rainbow formed over Halema‘uma‘u crater following an afternoon rain shower on February 22. Rainbows are often observed over Halema‘uma‘u, as mist and rain move across the caldera. This photo was taken from within an area of Hawai‘i Volcanoes National Park that remains closed to the public for safety reasons." ~ USGS-HVO USGS Activity Summary: "Kīlauea Volcano is erupting. Lava activity is confined to Halemaʻumaʻu with lava erupting from a vent on the northwest side of the crater. Field measurements as of February 22 indicate the lava in the western (active) portion of the lake in Halema‘uma‘u is 216 m (712 ft) deep. Webcams show intermittent crustal foundering. The eastern portion of the lava lake has a stagnant and solidified surface crust. SO2 emission rates remain elevated but continue decreasing; measurements on February 22 were 600 t/day." USGS Summit Observations: "The most recent sulfur dioxide emission rate measurements from February 22 are about 600 t/d and continue to gradually drop— this rate is lower than the emission rates from the pre-2018 lava lake (around 5,000 t/d). The summit tiltmeters show the inflationary trend of a new DI event started early this morning after midnight. Seismicity remains stable, with elevated tremor and one minor earthquake."
