Moving mountain

Etna Sliding Seawards!

The BBC reports that Mount Etna is sliding ESE at 14mm per year. Using high precision GPS stations an Open University geologist now has 11 years of data and says the slide is unmistakeable. The movement is possible because the volcano is sitting on slightly sloping platform of weak sediments.

This movement makes the measurement of the volcanoes expansion and contraction more difficult.
