A moderate earthquake measuring 5 on the Richter scale jolted Islamabad and parts of NWFP on Sunday but there were no immediate reports of damage, officials said. "It was a moderate intensity earthquake," said the chief of the Seismological Department Chaudhry Qamaruz Zaman. He said it was an aftershock of the massive October 8 quake that killed more than 73,000 people in the country. The shocks were felt at 7:49am in Islamabad and in Balakot and also in Mansehra and Swat districts, the officials said. The epicentre was 200 kilometres northeast of Peshawar. Two low intensity aftershocks, measuring 4.0 and 4.1, were felt later at 8:18am and 8:21am respectively, officials said.
