SANTIAGO (Reuters) - Chile's Llaima volcano, one of South America's most active, is spewing lava in southern Chile, the government said on Tuesday, ordering an evacuation just two months after the spectacular eruption of the Chaiten volcano further south.
Snow-capped Llaima, near Chile's picturesque lake region, erupted violently on New Year's Day, forcing the temporary evacuation of some tourists and residents from the surrounding Conguillio National Park, and then belched ash and lava in February.
On Tuesday the government ordered a 9-mile exclusion zone around the 10,253-foot (3,125 meter)-high volcano and ordered the evacuation of around 40 people from the area, about 435 miles south of the capital Santiago.
"There is renewed activity as lava is flowing towards the Calbuco River," said Juan Cayupi, a volcanologist at the state National Emergency Office. "(The lava) has reached around 800 meters (2,600 feet) to a 1,000 meters (3,300 feet) from the crater."
Cayupi said he flew over the volcano on Thursday and saw gases emanating from a small dome in the interior of the crater, but saw no lava at the time.
"The risk in this case is that there could be abrupt melting of snow because of the lava, which could produce torrents (of water and other material)," he added.
The renewed activity comes after Chaiten volcano, 760 miles
south of Santiago in Chilean Patagonia, started erupting on May 2 for the first time in thousands of years, spewing ash, gas and molten rock.
The nearby town of Chaiten has been caked in volcanic ash and the volcano continues to emit hot gas and ash. Chile's flagship carrier LAN suspended flights to the southern town of Puerto Montt on Tuesday, citing ash from the volcano. Jet engines need thorough servicing after coming into contact with the ash.
A 30-mile radius around Chaiten volcano was evacuated, and the area remains off limits to thousands of evacuees.
Ash from Chaiten, which initially soared as high as 20 miles, as well as rain swelled rivers in the area. Flooding damaged dozens of houses, carrying some wooden homes off their foundations.
Chile's chain of some 2,000 volcanoes is the world's second-largest after Indonesia's. Around 50 to 60 are recorded to have erupted, while a total of 500 are deemed potentially active.
