A fresh aftershock measuring 5.9 on the Richter scale has hit Pakistan.
Its epicentre was about 120km northwest of the capital Islamabad.
There have been no immediate reports of any casualties or damage after the tremor, which came 15 days after the devastating earthquake that left 53,000 people dead.
As the relief effort for victims in the region enters its third week, complaints persist about the distribution of aid.
There are many mountain settlements in Pakistan, and the section of Kashmir it controls, which have still not received any help.
President Pervez Musharraf has said the amount of funding pledged for reconstruction and rehabilitation is totally inadequate.
Yesterday, the UN's Humanitarian Co-ordinator for Pakistan said the earthquake relief effort must intensify if it is to save lives and help those most affected by the disaster before the onset of winter.
Jan Vandemoortele said officials were now in a race against time and were getting more tents, emergency shelters and helicopters to the most remote areas.
The quake killed at least 51,000 people in Pakistan and 1,300 in Indian Kashmir, as well as injuring more than 74,000 people and leaving over three million homeless.
