The seismology department at first erroneously gave the epicentre as Amritsar and put the quake's depth at 19 km. It later sent a revised statement to confirm the quake was in Tajikistan. It ascribed the error to a software mistake.

"Not since the earthquake of 2005 have the tremors in Srinagar been bad enough to force me out of the house. I grabbed a blanket & ran. I didn't remember to take my phone & so was unable to tweet earthquake while the damn ground was shaking," he tweeted.
"The epicentre of the earthquake is Tajikistan. Our preliminary findings said the epicentre was Amritsar. We have now revised the epicentre," J L Gautam, Operations Head of the NCS said.
According to M Rajeevan, Secretary in the Ministry of Earth Sciences, "The message was wrongly taken out by the system. It has been corrected."
The NCS had also said there were two quakes - the Tajikistan one occurred at 10.31 PM while the Amritsar quake happened at 10.34 PM.
"There was only one quake," Gautam said later.
