Officials say the 7.6 magnitude earthquake that struck close to Muzaffarabad in Pakistan-administered Kashmir on 8 October caused nearly 75,000 deaths and devastation that may take a decade to repair.
Pakistan has confirmed more than 73,000 deaths, most of them in Pakistani-administered Kashmir. India says nearly 1,400 have died in the sector it administers. Tens of thousands were injured and up to three million left homeless.
The World Food Programme says some 500,000 people in remote areas have received no aid at all. One of the biggest problems is meeting the demand for tents that can provide shelter as the cold weather worsens. Fears are mounting of a second wave of deaths from untreated injuries and exposure.

* Many roads in the affected area are damaged and/or impassable
Impact: Pakistan-administered Kashmir was the region hardest hit, with much of the capital, Muzaffarabad, destroyed. The head of United Nations relief operations, Jan Egeland, said he had never seen such devastation. The town of Bagh was badly affected and the impact in some remote villages remains unknown. Nearby Rawalakot suffered some damage, although most schools and colleges there were closed for a public holiday and casualties were not so high.
Landslides blocked roads and there was extensive damage to electricity, water and telephone infrastructure and all the city's hospitals.
Toll: The death toll in Pakistan-administered Kashmir alone may exceed 40,000, with some 70,000 injured, regional prime minister, Sikander Hayat Khan, said shortly after the quake. Federal figures now suggest that may have been an underestimate.
Aid: Muzaffarabad is the hub of the aid operation in Pakistan-administered Kashmir. Substantial amounts of aid have now arrived although it took several days to clear key routes on the mountainous roads. Helicopters are operating out of the city but have been grounded by bad weather for hours at a time.
Many of the city's 600,000 residents have had to sleep outside in the cold. A sports stadium is being used to house the homeless, care for survivors and distribute food and water.
There have been numerous reports of looting. Medecins Sans Frontiers are warning of a potential water-borne disease epidemic.

Toll: The government of North-West Frontier Province says nearly 38,000 people died in the province, but federal estimates have been much lower.
Aid: Pakistani military helicopters are ferrying aid into Balakot. Many of those arriving by road are local volunteers bringing private donations and tools to help trawl the rubble and bury the dead. Thousands of people are still living in the open and some villages further up the valley are still receiving little or no assistance.
Impact: The districts of Uri and Tangdar near the Line of Control are the worst affected, and 10 villages in the area are still cut off.
