  3. 2. Monitoring of Santorini (Greece) volcano during post-unrest period (2014-2016) with Interferometric Time series of Sentinel-1A

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Christos Bountzouklis; [2016]
    Keywords : Santorini Volcanic Complex; earth observation; volcanic hazard; SAR Interferometry; Sentinel-1A; physical geography and ecosystem science; Earth and Environmental Sciences;

    Abstract : Ground deformation monitoring is one of the main geoindicators that should be considered to assess volcanic hazard. Satellite earth observation data and Synthetic Aperture Radar (SAR) interferometry have been used continuously since 1992 to measure or study the temporal evolution of surface deformation in volcanic areas in conjunction with ground-based geodetic measurements.
