According to officials from Chile's national emergency office, Chile's Chaiten volcano spewed molten rock and a vast cloud of gas on Thursday. Last year, around 7,000 nearby residents had to be evacuated after the volcano erupted.
REUTERS - Chile's Chaiten volcano, which erupted spectacularly last year, spewed a vast cloud of ash as well as gas and molten rock on Thursday in a partial collapse of its cone, prompting a fresh evacuation.
Television footage showed a cloud of ash billowing into the sky over the town of Chaiten, which lies about six miles (10 km) from the crater.
Authorities evacuated 160 people from the area. Around 7,000 nearby residents were evacuated last year after the volcano, dormant for thousands of years, erupted. The government is planning to relocate the town.
Officials from Chile's national emergency office, Onemi, flew over the volcano and saw a kilometer-long crack in the cone of ash that has steadily grown in the crater, part of which has collapsed.
"Large quantities of gases and pyroclastic material were observed," Onemi said in a statement, adding that rains in the area combined with the ash could cause flooding in and around the town of Chaiten, located 760 miles (1,220 km) south of the capital Santiago.
However, while there was a large volume of ash, there had been none of the earth tremors or groaning sounds that accompanied the initial eruption last year, it said.
Interior Minister Edmundo Perez Yoma ordered all government personnel out of the area, and called on around 30 to 40 civilians who refuse to leave to follow suit.
"It is dangerous to stay in the area. They must leave," Perez Yoma said. "We have insisted for a long time now that it is completely irresponsible to keep living in the town."
"If they insist on staying there, they do so at their own risk," he added. "We can't keep risking public money or the lives of public workers to protect a few who don't want to face reality."
The government insists on moving the entire town. But some residents vow to stay put and are unfazed.
"I looked up and saw a tremendous column (of ash), just like in the beginning, one-and-a-half kilometers high," Claudio Chelgui, a resident who decided to return to Chaiten despite government warnings, told local radio.
"I didn't see much because it was overcast, and there was this huge column and fierce sound."
Emergency officials are exasperated.
"We have repeatedly said there is a red alert and that people should not be there, and if that had been respected, then police would not be evacuating people," an Onemi official said, asking not to be named.
He said the volcano has been in a permanent state of eruption since May of last year, when a cloud of debris soared as high as 20 miles (32 km) into the air. The cloud was kept aloft for weeks by the pressure of constant eruptions, covering towns in neighboring Argentina with volcanic ash.
Chile's chain of volcanoes, the second-largest in the world after Indonesia, includes some 2,000 -- of which 500 are potentially active.
