Notification of change in aviation color code

Katla

Time: 27. Jul 2024, 15:54 GMT

Color code:  Yellow 

Volcano id: 372030

Activity summary:
In the early hours of today, 27 July 2024, increased seismic tremor and earthquake activity begin within the Katla caldera. Presently, a glacial outburst flood is occurring from the eastern side of Mýrdalsjökull - the ice-cap overlying the Katla volcano. The cause of the flood is long-term geothermal activity beneath Mýrdalsjökull. As a precaution, we have temporarily increased the aviation colour-code to take into account the heightened possibility of volcanic unrest. Outburst floods from Mýrdalsjökull often occur during the summer months, especially July. However, the ongoing flood is larger than usual, hence in the increased response.
