It's one thing if the lava is heading for a smallish town but when there is a city in the way things can get very bad.
From The Watchers, January 31:
Þorvaldur Þórðarson, a professor of volcanology at the University of Iceland, has expressed concerns about potential volcanic activity under Húsfellsbruna, a vast lava field situated between Bláfjalla and Heiðmerkur. His observations, published in Morgunblaðin, stem from recent seismic activity in the area, suggesting that the Brennisteinsfjöll volcanic system, located near the Reykjanes Peninsula, may have been activated.
The series of earthquakes in this region has been interpreted as a sign of possible tension build-up at the bottom of the earth’s crust or magma accumulation in the molten rock reservoirs beneath the solid crust. This geological phenomenon is particularly significant considering that during the last eruption on the Reykjanes Peninsula, Húsfellsbruna was the lava that flowed closest to the capital city, Reykjavík.
Professor Þórðarson emphasized the gravity of the situation, stating that it is not out of the question for lava from this area to flow close to Reykjavík, potentially extending even further than during the last eruption. Given these risks, he advocates for the initiation of serious preventive measures and plans, stressing the importance of not relegating such measures to a secondary priority.
He also recalled a historical precedent, noting that the last time an eruption occurred this far north on Brennisteinsfjallariinn, lava nearly reached the sea at Straumsvík....
