Session Description South Asia is a seismically very active because of its complex geotectonic setups and uneven distribution of structural heterogeneities having bearing to collisional-subduction tectonics associated with active geodynamical processes. The frequent occurrences of trans-boundary moderate to strong earthquakes beneath south Asia as witnessed by the recently reported earthquakes , such as the 2011 Sikkim earthquake ; 2015 Nepal earthquake, 2016 Afghanistan earthquake. The intricate geodynamical processes have been playing an important role in seismogenesis beneath the region. There is no systematic studies has been carried out so far to understand what sub-surface geodynamical processes are responsible for making the entire crust and sub-crust vulnerable to the brittle failure. A series of seismological studies has been conducted in isolation without a common consensus on the nature of structural heterogeneities beneath the region by different researchers using different tools to understand causative factors for the frequent seismogenesis beneath the region. It is, therefore, imperative to estimate the varying degree of structural heterogeneities beneath the south Asia using huge quantity of high quality seismological data recorded by the existing seismological networks consisted of different types of seismographic stations ascribed to different institutions of south Asia by deploying 3-D / 4-D seismic tomography of the region to generate a common consensus among researchers on seismogenesis responsible for frequent disastrous earthquakes, creating panic in the region.
The session on “CRUSTAL DYNAMICS AND SEISMOGENSIS BENEATH SEISMICALLY ACTIVE REGIONS OF SOUTH ASIA” is proposed to invite researchers / scientists / seismologists/ academicians for comprehensive deliberations on seismic structure of the crust and sub-crust having supportive evidence from other independent geo-scientific (gravity, magnetotelluric, geodetic, etc) findings for better understanding of the hidden mystery of earthquake generating processes beneath South Asia.
