A strong earthquake centred in the towering Hindu Kush mountains shook a wide area of eastern Afghanistan and Pakistan early Friday, swaying buildings in the Afghan and Pakistani capitals.

There were no initial reports of damage or casualties from the quake, which struck about 12:21 a.m. Afghan time (1951 GMT, 3:51 p.m. EDT Thursday).

However, the temblor was centred in a remote mountain area where communications are poor and reports of casualties take time to reach the capital.

The earthquake had a preliminary magnitude of 6.2 and was centred in the mountains about 268 km northeast of Kabul and 230 km west of Mingaora, Pakistan, according to the U.S. Geological Survey.

Buildings shook in the Pakistani cities of Peshawar and the capital Islamabad, and the quake was felt as far east as Lahore near the Indian border, Pakistani television stations reported.

The Afghan Interior Ministry said it had no immediate reports of deaths or damage.

Paul Caruso, a geophysicist with the U.S. Geological Survey, said that even though the quake was centered in a remote area, casualties were still possible given the size of the temblor. Caruso said Friday’s quake was felt as far away as New Delhi.

Mr. Caruso said the area is capable of producing large earthquakes because of the compression created when what is now India slammed against the Asian continent millions of years ago.

He said the largest quake recorded in that area was 7.8 on March 14, 1965.
