People living in those houses are unharmed as they have moved to safer places apprehending damage to the structures, he said.
IAF's C-130 Hercules aircraft, commissioned after choppers engaged in the operations earlier failed to fly relief material to affected areas due to inclement weather, has also not been able to serve its purpose so far.
The plane returned from a sortie on Monday morning without dropping relief packages in affected areas due to overcast skies and low visibility conditions, NDMA member in charge of relief operations in the hill state, V K Duggal, said.
The aircraft is supposed to airdrop relief material in worst-hit Uttarkashi, Chamoli, Pithoragarh and Rudraprayag districts, including Kedarnath.
The process of cremating bodies is being carried out in Kedarnath area amid bad weather by a team of over 70 experts and trained personnel even as they are said to be facing food shortage.
