dc.description.abstract | The great Sumatra earthquake of 26th December, 2004 (0629 hrs IST) followed by the unique Indian ocean tsunami have added a new dimension to the natural hazard scenario of the country. Hitherto, the coastal region is associated mainly with such hazards like cyclones, storm surges, sediment slumps, coastal erosion, etc. Seismicity associated with compressional tectonics is another hazard in the Indian mainland, including the coastal regions. However, the mega event and the associated aftershocks mostly oriented along the Andaman-Nicobar islands arc indicate the possibility of Andaman-Nicobar area as a significant seismic hazardous zone of the country. In this paper, the seismicity of the Indian mainland, including the Andaman and Nicobar Islands is briefly reviewed. | |
