This fountaining was preceded by several days of significant precursory activity that included cyclic spatter and dome fountains from both the north and south vents that fed large lava flows on the crater floor including a flow from the south vent that reached 1,000 meters (3,300 feet) in length.
Sustained lava fountains erupting from the north vent are currently reaching heights of more than 200 meters (660 feet) and feeding a lava flow on the crater floor. Intermittent spatter continues from the south vent.
