Authorities evacuated a town and Blue Lagoon spa in southwestern Iceland on Tuesday as a volcano threatened to erupt for the eighth time. National broadcaster RUV says magma began flowing at a volcano near the town of Grindavik, where some 40 homes have been evacuated. The community was largely evacuated a year ago when the volcano came to life after lying dormant for 800 years. The Icelandic Met Office says magma flow was accompanied by an intense earthquake storm similar to previous eruptions.
