A major earthquake rocked Pakistan's southwest Saturday, sending people running into the street in panic just days after another quake in the same region killed 359 people, officials said.
The U.S. Geological Survey said on its website that a 6.8 magnitude quake was felt in Pakistan's southwestern Baluchistan province.
Pakistan's Meteorological Department measured the earthquake at 7.2 magnitude. The department said its epicenter was located about 150 kilometres west of the town of Khuzdar.
There were no immediate reports of casualties, said Abdur Rasheed, the deputy commissioner of Awaran district where both quakes were centred.

There may have been little left to damage after Tuesday's disaster. Few of the mud and homemade brick houses in the area survived the 7.7 magnitude quake that levelled houses and buried people in the rubble.
Since then tens of thousands of people have been sleeping under the open sky or in tents. Rasheed said they had received reports that some homes damaged but still standing after Tuesday's quake had collapsed Saturday.
He said they are trying to get information whether people were living in some of the partially damaged homes.
Chief Pakistani meteorologist Arif Mahmood told Pakistani television that it was an aftershock from this week's earthquake and such tremors might continue for weeks.
Least populated region
Pakistan television showed people at the main hospital in Awaran district fleeing into the street. In the provincial capital of Quetta, the tremor was so strong it prompted members of the local parliament to evacuate the building.
Baluchistan is Pakistan's largest but least populated province. The rough terrain and the lack of decent roads have made it difficult for rescue staff. The Pakistani Air Force has been making air drops of supplies and using helicopters to ferry injured people to medical care.
But at least two of those helicopters have come under fire from separatists, say Pakistani officials. The Pakistani military has been trying to suppress an uprising in the vast, arid province for years by separatists who want their own state for the Baluch people.
To the north Pakistan is dealing with militants who want to overthrow the central government and establish a hard-line Islamic state.
Peace talks with militants
Newly-elected Prime Minister Nawaz Sharif has vowed to pursue peace talks with the militants as a way to end the fighting. But the militants have given little indication they are interested in negotiations.
They initially rejected talks with the government and later demanded Islamabad release prisoners and begin withdrawing troops from the group's tribal sanctuary before talks could begin. Recent attacks have also called into question their interest in negotiating.
On Saturday, a spokesman for the Tehreek-e-Taliban criticized Sharif, saying his new government is not serious about holding peace talks. The spokesman, Shahidullah Shahid, did not explicitly reject the offer but his words gave little room for negotiations.
The comments appeared to have been sparked by an interview Sharif made with the Wall Street Journal during a trip to New York, in which he said militants must lay down their arms and follow the constitution. Previously Sharif had not given preconditions for the talks.
"By telling us that we will have to lay down arms and respect the constitution, the prime minister, Nawaz Sharif, showed that he is following the policy of America and its allies," the spokesman said. "We will hold talks with it only when it gets the real power to take decisions."
