The effusive eruption of the volcano resumes and has remained essentially unchanged since the last update.
Fountaining, about 49 ft (15 m) tall, continues from the only western fissure vent as the lava supply from the chain of vents stretching from the lake's center to its southern margin has ceased over the past few days.
The lava spattering continues to build the spatter cone above the eruptive fissure.
The western end of the lake shows a maximum elevation of approximately 780 meters (2559 ft) above sea level as measured by field crews on October 9, which is a 1 meter (3ft) increase over the past day and a total increase of about 37 meters (121 ft) since lava emerged on September 29.
The Hawaiian Volcano Observatory (HVO) reported that "The central island and several of the smaller eastern islets from the 2020 lava lake are still above the lake surface along with an island of the 2020 western vent rampart in the northwest part of the lake. The lava lake is not level across its surface due to the location of the vent in the western end. Areas closer to the vent are about 1-2 meters (3-7 ft) higher in elevation compared to the north and south part of the lake and 8 meters (26 ft) higher than the east end of the lava lake. Crustal foundering is mainly focused on the western part of the lava lake with lava flowing north and south around the central island through narrow cascades to reach parts of the eastern end of the lake."
Sulfur dioxide (SO2) emissions remain elevated at approx. 5300 tonnes/day measured on 8 October.
The seismic activity remains elevated but stable.
