Capturing a new phase of unrest at Santorini volcano, Greece
This is a Full Scientific Report resulting from NERC Geophysical Equipment Facility Loan 952, principal investigator Prof David Pyle.


Loan 952 supported the deployment of three cGPS receivers to augment geodetic studies of the first episode of active deformation and seismicity of the modern era at Santorini volcano, Greece. The instruments were deployed from July to October 2011, and were used primarily to complete a dense re‐occupation of the twelve Greek Military Triangulation Points on Santorini. Processing of these data, and comparison with the earlier occupations of the same network (in 1955 and in the 1980’s), provide the critical evidence that the episode of inflation at Santorini which took place from January 2011 – July 2012 was indeed the first major episode of deformation a this volcano since 1955; and most probably since the last eruption, in 1950. A report of our analysis of the geodetic data, combined with an analysis of the InSAR data for the period 2010‐2012 has recently been published in Nature Geoscience.
