On 18 December a volcano on the Reykjanes peninsula in south-west Iceland finally erupted, spewing glowing orange jets of lava surrounded by billowing clouds of red smoke. The population of Grindavík, a small fishing town nearby, had been evacuated in November after a series of small earthquakes. The government said the eruption did not present a threat to life; there were no disruptions to flights to and from Iceland, as this type of eruption does not usually produce much ash. Icelandic police have warned tourists to ‘think four times’ before attempting to get close to the eruption, after they had to rescue an exhausted hiker by helicopter. Iceland’s president, Guðni Jóhannesson, said: ‘Our priorities remain to protect lives and infrastructure. We wait to see what the forces of nature have in store. We are prepared and remain vigilant.’ The meteorological office said on 20 December that the power, seismicity and deformation of the eruption had decreased.
