Realizing the seismic sensitivity of the North East region, Nagaland University (NU) department of Geology organized a two-day workshop on Understanding Earth System Science in collaboration with Central Ministry of Earth Sciences (MOES), New Delhi seismology division which got underway at Hotel Saramati, Dimapur on Saturday. Giving an overview of earth system sciences (ESS), MOES advisor, Dr. B. K. Bansal affirmed that the central department was only into its fourth year but India was already at par with other developed countries in research with its improved infrastructural facilities over the years. ‘The North East region lies in one of the most hazardous seismic zones’, he said, and encouraged NU to put together training programmes on the subject matter on a regular basis. Dr. Bansal also called for introduction of ESS at university level.
Speaking at the inaugural programme as chief guest, NU Vice Chancellor (VC), Prof. K. Kannan expressed appreciation over the growing interest and enthusiasm meted out by both students and department on the subject of earth system sciences (ESS). He asserted that the system was a complex phenomenon where all its entities like geology, physics, math, geography etc. needed to be given equal importance and further urged students to keep a focus on all the compartmentalized subjects. The VC also emphasized on conducting continuous fire-integrated programmes to promote the subject and assured that he would be initiating proposal for creation of a school of ESS in Nagaland.
The first day of the workshop had technical sessions on Earthquake Monitoring & Evaluation by NEHU department of Geography, Dr. B. S. Mipun who highlighted on locating earthquakes through seismograph networks and discussed direct and secondary effects of earthquakes. He stated that direct effects were solely those related to deformation of the ground near the earthquake fault itself while most of the damages done by earthquakes were due to secondary effects which were not directly caused by fault movement, but resulting instead from the propagation of seismic waves away from the fault rupture. Dr. Mipun said those secondary effects result from the temporary passage of seismic waves but can occur over very large regions causing wide-spread damage.
Other related topics which were deliberated during the session included Seismo-Tectonic Sector of Manipur & Adjoining Areas by MU department of Geology, Dr. Arun Kumar; GIS & Remote Sensing in Nagaland by state Planning & Coordination department GIS & RS Centre, Er. M. Kithan; and Climate Change by MU department of Geology, Dr. R. P. Tiwari.
