The quake struck at 21:00:13 (20:00:13 UTC). Seventy-seven villages in the Friuli region were affected. Gemona del Friuli was greatly damaged and despite extensive emergency measures and international aid by the end of 1976 15000 people were still living in camping trailers, 1000 in tents and 25000 in evacuation centres. The damage was estimated at $4.25 million. Much of the town has since been reconstructed. The tremor was felt in Venice as well as neighboring Austria, Switzerland and Slovenia (at the time SFR Yugoslavia). In Slovenia, the upper Soča valley and the Brda area was particularly affected, with the village of Breginj nearly completely demolished. The earthquake damaged several buildings in Nova Gorica and was felt also in the Slovenian capital, Ljubljana.

The Italian Government nominated Chamber of Deputies member Giuseppe Zamberletti as coordinator of aid efforts on behalf of the regional administration. The national funds were assigned to the reconstruction of the damaged buildings by Zamberletti and the regional council of Friuli Venezia Giulia. From September to December 1976 all the earthquake victims were accommodated into prefabricated buildings, in order to better cope with the winter. Many local inhabitants lived in the Government supplied trailers for many years while homes were rebuilt. After Zamberletti's mandate the regional government of Friuli Venezia Giulia was able to completely rebuild many towns, thanks to an accurate resource management, however some towns took over a decade to fully recover. Nowadays, many years after the tragedy, the State's intervention, the earthquake management and reconstruction in Friuli Venezia Giulia are seen as a great example of efficiency and reliability.
