NEW DELHI: Two minor earthquakes awoke residents of the Indian capital of New Delhi early Tuesday, shaking buildings but with no immediate reports of damage.

India's Meteorological Department (IMD) said first a 3.1-magnitude tremor struck at 12.41 am local time (1911 GMT) at a depth of 10 kilometres, placing its epicentre in the capital city of nearly 10 million people.

Almost exactly an hour later, a second, marginally larger 3.3-magnitude quake also struck, the IMD said on its website.

An AFP reporter in Delhi said the tremor shook buildings audibly, and that there were at least two minor aftershocks.
