A volcanic eruption could destroy the Icelandic town of Grindavik or lead to extensive ash clouds, experts have warned. The country has been shaken by more than 800 small earthquakes, prompting fears that the tremors could disrupt the Fagradalsfjall volcano on the Reykjanes peninsula in the southwest of the country. Almost 4,000 people were evacuated from Grindavik over the weekend as authorities feared that molten rock would rise to the surface of the earth and potentially hit the coastal town and a geothermal power station. Ragga Agustsdottir, who lives close to Grindavik, said residents were fearful of what could happen if an eruption struck. “The scenario on the table now is that it will happen in or just north of the town of Grindavik. There’s no good option here,” she told The Independent. It comes as scientists warned Iceland’s south-western peninsula could face “decades” of volcanic instability following volcanic eruptions along the peninsula. “We expect to see volcanic eruptions along the peninsula, not just repeatedly in the same location. This instability could last decades,” the Icelandic Met Office’s Matthew Roberts told the BBC. Read More Iceland earthquakes: Are flights still running amid fears of volcano eruption?
