We are thinking of planning a trip to Bariloche next April 2012. Is is possible to get an idea whether the recent volcanic activity will continue to affect the region? e.g. the effect on the lakes etc if ther is no further activity?
SLH, Puyahue is still rumbling and emitting some ash and volcanologists are even warning there could be another big eruption with a "plug" of lava showing signs of giving way.
The Argentinian government has declared Bariloche and surrounds an "environmental disaster area". Millions of pesos in assistance are being made available to farmers and a big recovery and clean-up operation is underway. But have a look at this video report from Britain's The Telegraph http://www.telegraph.co.uk/earth/earthvideo/8580835/Chilean-volcano-fills-lake-with-ash.html of a lake filled with ash.
I'm no marine biologist, but even if there're are no more eruptions that's going to have an effect for years. almost 7 years ago
