The total death toll stood at 249, with at least 185 people killed in Pakistan and at least 64 more in Afghanistan, according to official reports from the two countries.
The death toll could climb in coming days because communications were down in much of the rugged Hindu Kush, where the quake was centered.
The U.S. Geological Survey put the epicenter near Jarm in Afghanistan's northeastern province of Badakhshan, 150 miles from the capital, Kabul, with effects felt in India and Pakistan.
