Travelers considering taking the ferry from Puerto Montt, or Isla Chiloe to Chaiten as a way to get to Patagonia should consider the following events and have a plan B:
On December 14, Volcan Chaiten erupted again. Here is a quote copied from Dr. Ralph Harrington's'
http://volcanism.wordpress.com/ site:
The latest SERNAGEOMIN bulletin on Chaitén, no. 65, covering the period 9 to 15 December 2008, has been released. The complete original report as a PDF is available via Werner Luis’s Chaitén site, and a condensed version has been published on the SERNAGEOMIN site. The newest dome, ‘New Dome 2′, which has been growing very rapidly, is clearly a very unstable structure and is experiencing major gravitational collapses, producing lateral explosions and
generating block and ash flows which are choking the Chaitén river and threatening the remains of Chaitén town with new inundations. There is also concern about the strength and stability of the south flank of the volcano’s original dome, which is bearing the weight of the new domes that have developed since May. A failure here would bring a large-scale collapse, swamping Chaitén river valley and town with vast quantities of ash and debris. In short, a very unstable and unpredictable situation.THIS DOES NOT MEAN YOU SHOULD NOT PLAN A TRIP TO THIS AREA. It only means that you should be prepared for your trip plans to change in the event of an "event". If a significant volcanic event happens, It is possible that your ship/ferry may be canceled, or if you are in route and , your ship/ferry may be diverted. Travel through Argentina into Futa and south is not affected.
