The Asian "Mega Tsunami" (2004) has struck most of the territorial nations of South Asia including the East Coast of India.  The NRDMS Division, Department  of Science and Technology, Government of India, New Delhi, has conceived and executed on All India Co-ordinated Programme on "Tsunami Disaster Assessment and Mitigation" through various institutions of expertise on Geomatics in Earth System Dynamics and the related natural disasters.  The Geomatics technology which includes Arial Photography, Photogrammetry, Satellite Remote Sensing, Digital Image Processing, GPS Surveys, GIS modeling etc. was used in this programme, geo-spatial data bases were created on Tsunami disasters over Natural, Physical and Human Resources and futuristic mitigation strategies were evolved there from.  The book illuminates the results of the studies carried out along the Indian Coast and a bird's eye view on the tsunami studies in Norway.    In addition, some special papers on the role of mangroves as Tsunami mitigator, Impacts o Tsunami over marine water quality, coral ecosystem etc; the administrator's experience over the tsunami crisis management, NGO's perspective, certain societal issues triggered by the killer Tsunami and citizen's perspective, etc. also find a place in this volume.
