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.
