On January 19, 1975 an earthquake of magnitude 6.8 occurred in the border districts of Himachal Pradesh, India. The earthquake caused considerable loss of life and varying degrees of damage to construction in the area. Traditional and recent buildings suffered extensive damage. Landslides, rock falls and avalanches caused considerable damage to the Hindustan-Tibet road. Extensive fissures in the ground developed at the epicenter. Greatest damage was noted along the N-S trending Kaurik-Chango fault following the Parachu and Spiti river valleys, suggesting its genetic interrelationship with the earthquake.
