"The Delhi Metro Rail structures are completely safe in case of any seismic or tectonic activities like earthquakes taking place in Delhi," a DMRC spokesperson said.
The spokesperson maintained that the Metro rail structures have all been designed to handle seismic events corresponding to zone 4 and all Indian codes (IRC:6, BIS:1893, BIS:13920 and RIS codes) which give guidance on designing of structures for earthquakes, and "have been strictly followed in all the structural construction of the Delhi Metro Project".
"But the same study in its conclusion clearly said that the direct risk to Metro structures and rail line structures have already been addressed and reduced owing to application of risk sensitive building codes," the spokesperson claimed.
"The Metro design engineers have adequately addressed all risks to Metro structures which may happen during an earthquake," the spokesperson said, adding that the structures are absolutely safe for carrying passenger traffic.
