Video footage shows a landslide in Hunza Valley, northern Pakistan after a massive earthquake hit on Monday.

The landslide killed a local teacher who was on her way home from school, Pakistani media said, and stirred up dust and blocked a road next to the valley.

About 11,000 houses have been damaged in Pakistan's northwest region due to the earthquake, but did not cause widespread damage to infrastructure, authorities said.

At least 266 people were killed, but the death toll could climb as road and communications links are restored to isolated villages and as winter sets in across the rugged Hindu Kush mountains where the earthquake struck.

Monday's initial quake of magnitude 7.5 was followed by seven aftershocks, of intensity ranging as high as 4.8, the US Geological Survey said.
