Kilauea (Hawai’i): (2 Apr) The high lava-fountain phase of the current eruptive episode (number 16), which had begun late on 31 March. continues: The volcano Observatory HVO wrote that the tall fountains started in Halemaʻumaʻu crater at 10:24 a.m. HST local time on April 1, 2025, about 12 hours after the start of the episode. „Fountaining from the south vent rapidly increased to over 200 feet (70 meters) in height by 10:40 a.m. HST and exceeded 700 feet (215 m) by 10:50 a.m. HST. Low dome fountaining and overflows continue from the north vent.
„Episode 16 was preceded by weak spattering in the north vent that began at approximately 5:20 p.m. HST on March 31, 2025. Since 6:00 p.m. HST, spattering became continuous and increased to low fountaining (15-30 feet or 5-10 meters high). Lava level gradually rose in the vent and began overflowing out of the north vent cone onto the floor of Halemaʻumaʻu at 10:57 p.m. HST on March 31.
„At south vent, small spatter fountains were first observed by field crews at 8:30 a.m. HST on April 1, but they probably were active deeper in the vent prior to that time. The south vent became more active at 10:12 a.m. HST on April 1 and began producing significant lava flows. Fountains in this episode are likely to exceed 1000 feet (300 meters) similar to episode 15.“
