Islamabad, Jan 24 (Agencies): An earthquake measuring 6.3 on the Richter scale shook northern Pakistan on Monday though there were no reports of damage or casualties due to the second major tremor to hit the country within a week.

Meteorological Department chief Arif Mehmood said the quake had its epicentre in Tajikistan at a depth of 89 km.

Tremors lasting about 10 seconds were felt in cities like Islamabad, Rawalpindi and Peshawar at 7.45 am.

The quake was also felt in areas across northwest Pakistan, including Mardan, Malakand Charsadda, Swat and the tribal belt bordering Afghanistan.

People left their homes in panic though there were no reports of damage or casualties, officials said.

A 7.3-magnitude temblor, which was felt as far apart as Delhi and Dubai, rocked southwest Pakistan on January 19.

About 200 mud houses collapsed due to that quake and two women died of heart attacks.

In October 2005, a quake measuring 7.6 on the Richter scale struck the Kashmir region and killed over 70,000 people.
