The lava flow within Halemaʻumaʻu crater (image: HVO)
The effusive eruption within Halemaʻumaʻu crater continues at fluctuating levels.
The lava lake is being fed by lava from the western fissure vent over the past 24 hours.
At about 10:00 local time yesterday, small and short-lived overflows have been observed at the western part of the lake followed by lava spill outs traveling to the south and west direction. Minor ooze outs occurred along the crater rim during the past 24 hours.
The summit tiltmeter detected a slight uplift (inflation) of the ground by 0.4 microradians accompanied by rapid increase between 7:30 and 13:00 local time yesterday related to lava flows from the west vent.
