An earthquake measuring 4,3 hit the Indian capital and its surrounding areas at dawn on Monday, shaking high-rise buildings, the weather office and witnesses said.
The epicentre of the tremor, felt at 11.13pm GMT, was near the border of New Delhi and the neighbouring state of Haryana, which surrounds the capital on its north, west and south.
The USGS put the time of the earthquake at 11.17pm GMT and said it measured 4,6, and was at a depth of 10km.
One local TV channel said there were some cracks in buildings near the epicentre but the report could not be independently confirmed. There were no reports of any major damage elsewhere across the city of 14-million people.
People in many areas were shaken out of their beds and gathered in open spaces as their doors and windows rattled violently, the Hindi-language Star News channel said.
A tremor of a similar magnitude hit India’s financial capital of Mumbai and the surrounding Konkan region on Saturday but caused no damage.
