Multitemporal SAR coherence analysis: Lava flow monitoring case study

This paper is focused on an operational case study related to the adoption of a Multi-Temporal Coherence (MTC) color composite approach to support monitoring activities of volcanic eruption events. A specific case study related to the volcanic eruption in Fogo Island (Cape Verde), which started on late November 2014 will be presented and discussed. A MTC analysis based on data acquired by the COSMO-SkyMed SAR satellite constellation of the Italian Space Agency is describe in details. The thematic accuracy of the MTC based analysis is assessed exploiting as comparison data lava extents derived by very high resolution satellite imagery acquired in the same period.
