Researchers in Hawaii have captured dramatic footage of a "firehose" of red-hot lava plummeting down a cliff into the Pacific Ocean, sending fragments of lava and clouds of gray smoke into the sky. It's coming from the big island's Kilauea volcano, which has been erupting since January 1983. On New Year's Day, about 21 acres of rock from the Komokuna lava delta collapsed. After that, "the exposed lava tube continued to feed a cascade of molten rock down the steep sea cliff," according to the USGS Hawaiian Volcano Observatory. That's what we're looking at now.
