A 5.1-magnitude earthquake struck just outside Islamabad July 25, the U.S. Geological Survey said, but local officials said there were no immediate reports of damage or casualties.
Residents of the Pakistani capital reported buildings and vehicles shaking after the quake hit at 1:59 am local time.
The tremor struck at a relatively shallow depth of 26 kilometers, USGS said, with the epicenter located 15 kilometers to the northeast of Islamabad.
The quake was felt in several Pakistani cities in the provinces of eastern Punjab and northwestern Khyber Pakhtunkhwa, Ghulam Rasul, a senior meteorologist at the Pakistan Meteorological Department said.
The local meteorologists put the size of the quake at 4.6 magnitude and the depth at just 10 kilometers.
Pakistan straddles part of the boundary where the Indian and Eurasian tectonic plates meet, making the country susceptible to earthquakes.
It was hit by a 7.6-magnitude quake on October 8, 2005 that killed more than 73,000 people and left about 3.5 million homeless, mainly in Pakistan-controlled Kashmir.
