Color code:  Orange 

Volcano id: 371030

Activity summary:
The eruption in Fagradalsfjall continues at similar rate as before. From the latest Pléiades image acquisition (LMI) the extrusion rate has been assessed to be about 5.3 m3/sec. The last DOAS traverse, performed on the 28.03, gave an SO2 flux estimate up to 19 kg/s. The gas plume height as assessed from calibrated images this morning gave a plume up to 1.0 km asl. There is no production of ash and tephra. A minor seismic activity is still ongoing and localized around the Fagradalsfjall area. Because of the lack of ash and tephra emission in the atmosphere, the aviation color code for Fagradalsfjall-Krýsuvík is maintained ORANGE as there are no imminent hazard for the aviation.

Cloud height:
Few hundreds of meters up to 1.0 km asl of volcanic gas plume. No ash production.

Other cloud information:
Few hundreds of meters up to 1.0 km of volcanic gas plume. No ash production.

Remarks:
Volcanic SO2 is expected to be drifted predominantly to the South in the coming hours and for the all day tomorrow. Lava flows are currently a very localized hazard.
