We consider ground seismic acceleration in static seismic analysis while our piping supports are taken from aboveground structures and equipments, quite tall!

Is it not against seismic codes in US and India as fire resulting from leakages post earthquake can result in loss of costly infrastructure?
I understand that east coast is not earthquake prone.But, amplified acceleration shall be considered as per seismic codes in India, I understand.
If I am wrong, please correct me.

PS:I dislike ignoring axial tensile force in flange leak check by NC method which can hamper public safety while providing short term gain in productivity in piping stress analysis. By shortcuts, we gain in short term, but build a risky future. Often fire happens in piping flange leak due to this short cut!
