A moderate earthquake measuring 5.5 on the Richter scale hit Uttarakhand on Wednesday night, at around 8.45 p.m., causing tremors in the hill state and adjoining areas, including Delhi and NCR.
No loss of life or property was, however, reported from anywhere.
Although the earthquake lasted for only a few seconds, it triggered panic at many places, especially Dehradun -- the state capital of Uttarakhand -- and people rushed out of their houses.
The India Meteorological Department (IMD) official said the epicentre of the earth quake was 121 km away from Dehradun, in Rudraprayag, and at a depth of 30 km.
"The epicentre was in Rudraprayag of Uttarakhand and the tremors felt in Delhi and NCR were the impulses," he told IANS.
This is the second earthquake in Uttarakhand in the past 24 hours. On Tuesday, a 3.3 magnitude quake was reported in the state.
Strong tremors were felt in Uttarakhand' s Nainital, Udham Singh nagar, Champavat, Dehradun, Pithoragarh, Bageshwar and Hrishikesh.
In Uttar Pradesh, tremors were felt in Meeru and Baghpat. Tremors were also felt in Himachal Pradesh's Shimla, Kullu and Mandi, and some parts of Punjab and Haryana.
