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

Updated: Aug 8, 2022 20:06 GMT - Refresh

ground deformation varies, currently inflating

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

Lava lake level fluctuated since 30 June, currently dominated by a decreasing trend (image: HVO)

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.

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

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.

lava flow eruption continues

The activity of the volcano has been stable during the past month.
The lava flow from the western vent continues to supply to the Halemaʻumaʻu lava lake along the southern, northeastern, and northwestern rim of the crater floor.
Electronic tilt monitoring registered a summit deflation over the past 24 hours.
The Hawaiian Volcano Observatory reported that the crater floor had seen a total rise of about 106 meters (348 feet) and that 77 million cubic meters (20 billion gallons) of lava had been effused since the beginning of this eruption on September 29, 2021.

We truly love working to bring you the latest volcano and earthquake data from around the world. Maintaining our website and our free apps does require, however, considerable time and resources.
We need financing to increase hard- and software capacity as well as support our editor team. We're aiming to achieve uninterrupted service wherever an earthquake or volcano eruption unfolds, and your donations can make it happen! Every donation will be highly appreciated. If you find the information useful and would like to support our team in integrating further features, write great content, and in upgrading our soft- and hardware, please make a donation (PayPal or Online credit card payment).

Planned features:
  • Improved multilanguage support
  • Tsunami alerts
  • Faster responsiveness
Thanks to your past donations, these features have been added recently:
  • Earthquake archive from 1900 onwards
  • Detailed quake stats
  • Additional seismic data sources
