Krysuvik-Trolladyngja (Iceland) - Report for 10 August-16 August 2022 - NEW

The fissure eruption in the Krýsuvík-Trölladyngja volcanic system that began on 3 August continued in the Meradalir valley during 10-16 August.
Lava erupted mainly from a central cone and flowed ESE.
According to the Institute of Earth Sciences the effusion rate had notably decreased, from an average of 11 cubic meters per second during 4-13 August to 3-4 cubic meters per second during 13-15 August.
A news article stated that the effusion rate significantly decreased during 0530-0630 on 13 August based on information from IMO staff who were investigating the eruption site for new changes.
The Institute of Earth Sciences estimated that 10.6 million cubic meters of lava had covered an area of 1.25 square kilometers by 15 August.
Data collected during an overflight on 16 August indicated that the effusion rate had further reduced to 2 cubic meters per second during the previous day, though the uncertainty in that estimate was high.
On 16 August residents reported seeing a purple-tinged sulfur dioxide gas cloud over the eruption area slowly drifting SW during sunrise.
