Bhubaneswar is comparable to Ahmedabad in respect of seismic vulnerability and can have similar damage to its building infrastructure in case of a likely earthquake of comparable intensity of shaking to that experienced in Gujarat in 2001.

First shows , the seismic zones in India and 2nd shows major earthquakes of the last 5 centuries. These two should give you a better idea of the earthquake risks in Bhubaneswar.
All buildings greater than five stories high in Seismic Zone III and above must comply with IS 13920. This has been stated by Prof Durgesh C Rai, eminent earthquake engineer from IIT, Kanpur in his studies covering all aspects of the earthquake engineering in the context of Indian experience.
Bhubaneswar falls in the same seismic zone III classification as Ahmedabad, but Bhubaneswar is far less likely to witness the sort of damage that Ahmedabad felt in 2001.
This is because Ahmedabad is about a hundred kms away from areas classisfied as zoneIV and zone V, which are regions of heavy seismic activity.
Bhubaneswar, on the other hand, is close to 500kms away from the closest region classified as zone 4. In fact most of Orissa is actually classified as Zone II, which is lower than Bhubaneswar regions Zone III classification.
