Elevated earthquake activity beneath the summit began at approximately 2 a.m. HST this morning, December 23," the National Park Service said in a news release. The USGS changed the advisory levels to warning after Kilauea started erupting around 2:30 a.m. which USGS confirmed on webcams. The advisory level has since been downgraded to watch. "This one came on really fast," Ken Hon of the USGS told Wake Up 2Day. "What we saw was a swarm of earthquakes as a crack opened up and allowed magma to come from the magma chamber up to the surface." A line of fissures was seen with lava fountains at the base of Halemaʻumaʻu. Initially the fountaining was reaching heights of 250 to 300 feet but are now stabilized at well over 100 feet.
