However, according to the US Geological Survey, the strength of the earthquake was measured 5.2 on the Richter scale.
The quake took place 9km below the surface. The tremors were felt for less than ten seconds.
“The intensity was 4.9 and the epicentre was Bahadurgarh, Delhi-Haryana Border,” a senior MeT official said.
There were no immediate reports of any casualty. The fire brigade and police said they have not received any immediate calls of casualty or damage.

This is the third tremor in Delhi, which is among the 30 cities which fall in the high risk seismic zone, since September last year.
