Fagradalsfjall (Reykjanes Peninsula, Iceland): Authorities and geophysicists consider to built artificial dams in order to avoid damaging fiber optic cables and other important infrastructure.
Artificial dams are supposed to divert the lava flow expected in Suðurstrandavegi valley within a week or months. Barriers work only temporarily, but given the experiences from the last eruption in 2021, the idea is well worth it.
Engineers are expected to design the same dams in advance in case of the lava overflows into the Suðurstrandavegi valley.
...12 Aug:
The activity at the eruption site continues with little changes since yesterday, but has been stable for now.
The IMO institute reported that the main lava flow direction has transited from eastward to northward, but not into Suðurstrandavegi valley yet. According to the University of Iceland, it seems the flow continues to travel through narrow and steep chutes which makes the effusion rate higher and more abundant. A rising volume of slowly spreading field of lava on the east has been reduced due to direction change.
