 and this resulted in about 25,000 lost lives. It has been estimated that if the earthquake had occurred 5 minutes later, children would have not been in schools' unstable buildings. This short time delay could have saved many lives. The earthquake was followed four minutes later by a magnitude 5.8 aftershock.

It cost over £3 billion ($3.5 billion USD) to repair the damaged property.

 was also temporarily closed down because of the earthquake.

Since most of the hospitals in the area were destroyed, and because of extremely low winter temperatures, officials at all levels were not ready for a disaster of this scale and the relief effort was therefore not launched properly. The Armenian government let in foreign aid workers to help with the recovery in the earthquake's aftermath, and this was one of the first cases when rescue and relief workers from other countries were allowed to take part in relief works in the Soviet Union. Mikhail Gorbachev, on a visit to the United States, cut his trip short and went directly to Armenia to visit the quake-affected areas.
Contributions poured in from around the world to help the earthquake victims through the winter and to rebuild much of the housing. Spitak was totally rebuilt in a location next to the previous town, with many neighborhoods having very distinct architecture reflecting the country which donated or built the homes there. A monument expressing the appreciation of the Armenian people for assistance from the U.S. was erected in Washington D.C. in 1990.

. During the earthquake, the northeast-facing side of the Spitak section rode up and over the southwest-facing side. The main shock occurred near the intersection between the Alavar fault and the Pambak-Sevan fault.

Despite the fact the earthquake was only of a moderate size, with a magnitude of 6.9, there were various factors contributing to the large scale magnitude and destruction that followed. These included the time of day, freezing winter temperatures, poor soil conditions and inadequate building construction.
