Hawaiian Volcano Observatory: Episode 18 of the ongoing Halemaʻumaʻu eruption resumed with lava overflowing the south vent at 3:20 a.m. HST on April 22 followed by the onset of fountaining from both vents at 3:30 a.m. HST. Lava began overflowing the north vent at 3:47 a.m. HST. Fountains are currently over 650 feet (200 meters) high at the south vent and over 160 feet (50 meters) at the north vent. Both fountains are feeding a vigorous flow on the floor of Halemaʻumaʻu crater. Lava has currently covered about over 20% of the floor of Halemaʻumaʻu crater. Strong deflation accompanied the onset of lava flows at 3:20 a.m. and tremor increased with the onset of fountaining from both vents.
