Haroon just got back after delivering aid to Muzaffarabad, the capital of Pakistan-administered Kashmir and probably the worst hit place. It is situated very near the epicenter of the quake.
According to him, conditions there are the worst imaginable. Camps are setup, but the recent rains have caused more mudslides. Roads are open and accessible, though with a certain level of danger. They are as wide as before (i.e. pretty narrow) and the capacity is severely limited.
People are moving out of the cities, though the villages are still places where help is needed the most. The army is the main organization administering the aid so I think it would be a good idea to coordinate with them for any relief efforts.
Another advice. If you are delivering aid anywhere, avoid handing out medical supplies to the locals. Give it to professionals instead to avoid unnecessary wastage.
