Given that Italy is the one country in Europe (apart from Iceland) that understands volcanoes
I don't know about that, SSK, I live an hour's drive from the Garrotxa with its 70 dormant volcanoes, dormant yes but a strong smell of sulphur from many of them.......the city of Olot is built over the region and there are three volcano cones pushing up through the city itself. Historically there has been a major erruption in the Garrotxa roughly every 10,000 years - the last one was 13,000 years ago, so any time now......
