In IIT roorkee there is no interview, admission in M.Tech Earthquake Engg on the basis of GATE score. There are three streams in earthquake engineering Structure Dynamics, Soil dynamics and SVRA. Most of the students are not aware about this department. Structure dyn is more demanding then soil and SVRA is last.

Now come on the your answer for Structure dyn the last gate rank near by AIR 1000 for gen category , OBC 3000, SC & ST near 5000. For soil dynamics more higher like 1400 for general category. SVRA is the hope of last gate ranker and it goes AIR 1800 for general category. These all ranking are based on Spot round at IIT Roorkee.

Best of Luck !!
