This post is the first of a new series I plan to write, on the techniques used to study and monitor volcanoes. The reason science is the best method we have of investigating the world around us is not so much what we know, but how we know it. I thought I'd start with a technique that always amazes me; we can measure centimetres of ground deformation over an area of many square kilometres, from an altitude of 800 km. Interferometric Synthetic Aperture Radar, InSAR for short. read more
