Last week, I was 2000 miles away off the north-west coast of Africa on the island of Tenerife. According the popular belief Tenerife is made out of the strato volcano called Teide, but actually Teide is simply a small volcano nestled in the crater of a much larger and more terrifying volcano called Las Cañadas. But this is not the end of the volcano-ception, Cañadas itself is sat on top of a much older shield volcano called Teno, but this was a less explosive sort of volcano.
We spent the week studying the ash, pumice and pyroclastic density current deposits formed in the multiple eruptions of Las Cañadas – some of these layers were 8 m thick! If you want to get a feel for the type of eruption, look at the eruption of Mount Pinatubo in June 1991 and think much bigger! (There’s a great documentary about it too). This trip was probably the best field trip I have been on so far – but as always I feel that it is best explained to you through pictures:
As always if you wish to know more about volcanoes or field trips feel free to ask me! Please do because I actually love talking about it 😛
