Experts have warned of a potential volcanic eruption near the town of Grindavik, which could lead to extensive destruction or ash clouds. This concern follows over 800 small earthquakes in the region, indicating possible activity from a volcano on the Reykjanes peninsula in southwest Iceland. Nearly 4,000 residents of the town were evacuated amid fears that molten rock could surface, threatening the town and a nearby geothermal power station. Scientists from the Icelandic Met Office have warned of a prolonged period of volcanic instability on the peninsula, possibly lasting decades, with eruptions expected in various locations. On 15 November, Thorvaldur Thordarson, a volcanology professor, assessed the probability of an eruption at 30%, a decrease from earlier higher estimates. Despite fears of an impending volcanic eruption, flights in and out of Keflavik international airport, only ten miles from the eruption site, are continuing as usual. In 2010 another volcano in Iceland grabbed the world's attention by spewing ash into the atmosphere and bringing European air travel to a halt.
