Some are staying in guesthouses, while schools have been turned into makeshift shelters packed with stores of bottled water after a blanket of volcanic ash contaminated ground water.

Only a few dozen people remained in Chaiten, whose snow-capped volcano of the same name erupted on Friday, triggering earth tremors and spewing a cloud of ash two miles (three km) into the air. There is no record of the volcano erupting in the last 2,000 years, according to Sernageomin, a government mining and geology agency.

Ricardo Larenas, 32, took his wife and two children to safety in Puerto Montt, then went back to protect their belongings.

"I came back here after living in Norway for 16 years. I brought a lot of money with me and frittered it away. My furniture workshop is all I have left," he said.

Southern Chile is fragmented into hundreds of small islands and fjords. Some residents had never ventured from Chaiten itself until the 3,280-foot (1,000-meter) volcano six miles (10 km) away forced them to go.

"I am amazed how big the continent is," said Claudia, an elderly resident, on arriving by boat at the southern island of Chiloe, mistaking it for mainland Chile. "I have never left Chaiten before."

She clasped a plastic bag containing a few basic items she had managed to salvage before being evacuated.

Technicians were dispatched to restore phone in the area, 760 miles (1,220 km) south of the capital of Santiago, and ensure electricity supplies while experts took water samples.

Before they were ferried to safety, some people in the area wore white surgical facemasks to avoid inhaling the ash that lay 6 inches (15 cm) deep in some areas.

The National Emergency Office said volcanic activity continued, with fine ash falling. Visibility remained poor as ash clouded the skies and the smell of sulfur hung heavy in the air.

"The panorama here is pretty complicated," Interior Minister Edmundo Perez Yoma said during a visit to the area. "We have completed the first phase of the operation, which was the evacuation of practically all of the local population.

"We don't know if this is a situation that will last days, or weeks or even more."

Schools were closed on Friday, and hospitals treated people for irritated eyes and breathing difficulties.

Across the nearby border in Argentina, authorities in Chubut province asked residents to avoid rubbing their eyes and to wear glasses and long sleeves to avoid ash making contact with skin.

Chile's 2,000 volcanoes include two of Latin America's most active -- Villarica and Llaima. Scientists say some 500 are potentially active. Chile has the world's second most active string of volcanoes behind Indonesia.

Llaima, about 435 miles (700 km) south of Santiago, erupted on New Year's Day, spewing ash and molten lava and forcing dozens of tourists and staff to evacuate a wilderness park.

It also belched ash in February and lava crept down its slopes.
