A volcano in south-western Iceland has erupted, spewing red streams of lava in the latest display of nature’s power, triggering the evacuation of the popular Blue Lagoon geothermal spa. The eruption began in the early afternoon following a series of earthquakes north of Grindavik, a coastal town of 3,800 people that was also evacuated. The Met Office said lava was shooting about 50 metres (165ft) into the sky from a fissure about one kilometre (1,100 yards) long. The Blue Lagoon thermal spa was evacuated before the eruption began, national broadcaster RUV said.
