Fagradalsfjall

Time: 02. Aug 2023, 17:29 GMT

Color code:  Orange 

Volcano id: 371032

Activity summary:
The minor effusive eruption which commenced on 10 July has been declining over the past few days. The data collected by colleagues at the University of Iceland, the Icelandic Institute of Natural History and the National Land Survey of Iceland on 31 July show an extrusion rate of about 5 m3/s for the period 23-31 July, which is almost half of what was measured the previous time. The GPS data indicates signs of deflation at depth which probably coincides with the deep source feeding the eruption. The overall dataset confirms that the eruption is slowly decreasing, and it might possibly come to an end in the coming days/weeks.

Cloud height:
The gas plume height has been within 1-2 km asl as assessed by calibrated cameras most of the time, and it exceeded 2.5 km on 1 August.

Other cloud information:
Today a very thin and faint plume is hardly detectable by eye.

Remarks:
Lava flows, gas pollution, grass and moss fires continue being the main hazards posed by the current eruption on a local scale.
