The Chaiten volcano in northern Patagonia, Chile, had been dormant for 9,500 years under its obsidian dome before erupting spectacularly and without warning one year ago, spewing ash 20km (12 miles) into the air and forcing the local population to flee.
In February it exploded again with renewed fury, ripping a 1km tear in the south side of the dome and prompting the government to order the indefinite evacuation of the 200 residents who had returned during the previous year. But today, 70 of the residents stubbornly refuse to leave, living day-to-day without running water or electricity and in constant danger of being swallowed up by new volcanic activity.
