Unfortunately there are not a lot of helpful homepages, organizations or a ministry in Argentina which supplies us with information about volcanoes. On top nowbody really knows what is going to happen. The Russians fly to Mars but we have still no clue when or which Volcano is going to go off. So the little information there is we have to get mostly from our neighbour, Chile. Here is a good homepage if you are interested in updates on Volcanoes. On the other hand it is also true that most active volcanoes are in Chile and not in Argentina. We do not have lots of active volcanoes but get the ashes from Chile!
