Hawaii News
A new third eruption this year at the volcano's summit started.
Following a period of strong seismic activity and rapid inflation over the past three weeks, the new effusive eruption within the Halemaʻumaʻu crater commenced at 03:15 PM local time yesterday.An opening of vents was reported as dynamic as usual. A new eruptive fissure, currently spreading from the eastern margin of the lava lake across the down-dropped block to the east, actually consists of a chain of several vents, erupting small lava fountains. Mild spattering continues to generate emissions of incandescent and fluid lava that layers the recent lava lake. The live-stream video of the activity within the Halemaʻumaʻu crater is available here.
Sulfur dioxide (SO2) emissions may reach their peak for the next few days, gradual decrease is expected thereafter.
Therefore, the Hawaiian Volcano Observatory (HVO) raised the alert status for the volcano to "Red".
There are no indications of any significant changes near populated areas, and thus no increased lava threat to people.

Update Sep13:
The effusive eruption within the Kilauea caldera continues.
Several active vents of the eruptive fissure placed on the easternmost and westernmost part of the downdropped block became inactive yesterday. The number of active lava fountains, therefore, shrinked into the range of approx. 750 meters (0.5 miles). Lava fountains are arranged in an east-west trending linear from where continue to feed the lava lake through a lava tube system. The eastern rim of the crater has been covered by new lava flows.
Several spatter cones have been building around the active fissure vents.
A height of lava fountains has decreased since the eruption onset but remains high about 10-15 meters (32-50 ft).
The new lava lake level has increased by 5 meters since the eruption started.
Ground deformation instruments continue to detect the summit area deflated over the past 24 hours.
Satellite-based measurements of SO2 concentrations in the atmosphere measured 49,000 tonnes on 11 September.
The live-stream video of the activity within the Halemaʻumaʻu crater is available here.
