The road of the film has been obstructed by a small landslide, but the damage in eastern Nepal is not as acute as in the central part of the country. Saturday April 25th's M7.8 earthquake registered M5.7 in Sankhuwasabha (as measured at the disctrict headquarters of Khandbari). Article about road here.
We are currently in Kathmandu (safe and doing well, please don't worry) and will return to the east in early May. To learn more about the effects of the earthquake I would suggest searching facebook, as that is the way most information is being organized and relief efforts are being coordinated.
May 29th update: Just back from a trip to Khadbari and back and damage from the earthquake truly is minimal on this side of Nepal. Some damage to houses was visible, but by no means extensive, and there were no blockages on the road itself.
