This process marked a turning point, as government ministers and international organizations collaborated under this framework with local engineers and local people to organize the systematic rebuilding of the city.
Eighty-five to ninety percent of buildings and infrastructure in the Bam area were either damaged or destroyed, with 75% of houses being completely destroyed, plus 70-90% of Bam's residential areas.
Earthquakes occur as the result of both reverse faulting and strike-slip faulting within the zone of deformation.
Preliminary analysis of the pattern of seismic-wave radiation from the December 26 earthquake is consistent with the earthquake having been caused by right-lateral strike-slip motion on a north-south oriented fault.
The earthquake occurred in a region within which major north-south, right-lateral, strike-slip faults had been previously mapped.
The Bam earthquake is 100 kilometres (62 mi) south of the destructive earthquakes of June 11, 1981 (magnitude 6.6, approximately 3,000 deaths) and July 28, 1981 (magnitude 7.3, approximately 1,500 deaths).
These earthquakes were caused by a combination of reverse-motion and strike-slip motion on the north-south oriented Gowk fault.
The rupture length of the earthquake was estimated to be around 24 kilometres.
More than half of the quake was produced from its southern segment
On January 8, the International Federation of the Red and the U.N. launched an international appeal for relief together at a conference in Bam, appealing for $42 million and $31.3 million respectively.
In response a reported 44 countries sent in personnel to assist in operations and 60 countries had offered assistance in the aftermath of the earthquake.
During the nights following the earthquake, the temperatures would drop to "bitterly cold" extremes, effectively killing some survivors.
