I have just discovered this website and was fascinated in 2004 when I was in Tenerife on holiday in May/June and heard about the activity the day after I had gone so far up the mountain. (they were not issuing any passes for the top - but were cagey as to why) and commenting back at a local cafe that myself and another few people thought they could smell rotten eggs (sulphur!).

We read local papers and found that the magma was believed to be only 3 kilometres from the surface at that time and that eide had been put on orange alert and they genuinely believe that there will be an eruption however at that point it was "could be this year - could be 1000 years. I was hoping at least a minor spat would happen whilst I was there but was disappointed!
