Kilauea Volcano, Hawai’i: current activity and eruption update

Volcano Discovery on the July 27th update of the eruption update of Kilauea.  Join us for a bucket list experience on one of our Volcano Explorer tours departing from Kona or Waikoloa.   Sit back, relax and enjoy viewing the volcano at Hawaiʻi National Volcanoes Park – the crown jewel of the Big Island.

ground deformation varies, currently inflating

Update Tue 19 Jul 2022 23:03

The effusive eruption at the volcano continues.
A slightly increasing inflationary trend continues at the Kilauea’s summit. The previous, relatively flat deflation switched to the current uplift in the early morning of the July of 15. A short-lived ground decline has been recorded at 07:30 local time yesterday, but reverted back again into rising values.
The lava level of the active lake surface remained at the level of the bounding levees. Two lava ooze-outs have been formed at midnight and 02:00 local time tonight.
Sulfur dioxide (SO2) emissions reached to a 1700 tonnes/day on 18 July.

decreasing lava lake level

Update Sun 03 Jul 2022 14:30

A current deflation pattern followed ground variations at the volcano beginning in the early morning on 30 June as seen in the deformation graph.
Summit tiltmeters registered a changing uplift and subsidence throughout the past two days accompanied by the Halemaʻumaʻu lava lake fluctuations in depth, currently having a lowering trend.
Sulfur dioxide (SO2) emissions reached to a 1100 tonnes/day on 30 June.
The western eruptive fissure vent continues to feed the active lava lake with sporadic overflows within Halemaʻumaʻu crater.

deflation-inflation pattern continues

Update Sun 26 Jun 2022 08:52

Summit instruments registered a deflation around 17:00 local time on 24 June.
From available HVO monitoring data, a steep drop in ground deformation and lava lake level may likely reflect magma flux revert again and confirms ongoing varying values. This summit deflation-inflation cycle at the volcano continues to fluctuate almost over the last week and will likely transit back to inflation soon.
Sulfur dioxide (SO2) emissions reached to a 2300 tonnes/day on 24 June.
The western eruptive fissure vent continues to feed the active lava lake with sporadic overflows within Halemaʻumaʻu crater. The crater floor currently consists mostly of solidified lava including crater islands from 2020-21.

uplift followed magma intrusion at midnight

The recent deflation pattern at the volcano over the last 48 hours reverted into an inflation in the midnight of 20 June.
This was followed by the ground uplift by approx. 1.5 microradians associated with the lava lake level by 3 meters indicating a rising batch of magma towards the surface.
The lava continues to keep the ooze out from the western fissure vent active along the southern and northern rim of the crater floor within the Halemaʻumaʻu lava lake.

deflation continues

Update Mon 20 Jun 2022 19:59

Summit instruments detected a deflation starting around the midnight of 18 June with ground subsidence by approx. 2.5 microradians. The lava lake level has dropped by about 3 meters (10 ft) since the ground deformation started. This is most likely reflects reverts of magma batch movements under the surface leading to the lava lake sinking.
The lava flow from the western vent continues to supply to the Halemaʻumaʻu lava lake along the southern and northern rim of the crater floor.

UPDATE 20 June:
The deflation continues and the ground has sunk by 1 more microradians with the lava lake dropping by 2 meters (6 ft) over the past 24 hours.
