Changureh - Avaj Earthquake of June 22th 2002

Changureh - Avaj Earthquake of June 22th 2002

 

On 22 June 2002, at 07:28:20 local time, a destructive earthquake struck some vast regions in Qazvin, Hamedan and Zanjan provinces in Iran. This earthquake was also felt in Tehran, Kermanshah, Qom, Central, Ardebil and Gilan provinces as well. The magnitude of this earthquake as announced by the Earthquake Information Center of the US Geological Survey was 6.5 in Richter scale.

 

The earthquake was recorded by 65 digital accelerographs installed in different points of the area. The number of accelerographs are 78 arrive. The maximum acceleration recorded in this event so far is about 0.5g at the Avaj station, which is situated 26km from the earthquake hypocenter. There is no doubt that the acceleration in regions closer to the epicenter of the earthquake is higher than that recorded by Avaj station and this high acceleration may be regarded as one of the major reasons of destruction and collapse of rural buildings. 

 

The macro-seismic area in Avaj consists of numerous faults and fractures which are of north-west - south-east direction. The epicenter was located at the west and North-west Mountains of Avaj area. The macro-seismic area of Avaj earthquake is located in the vicinity of the macro-seismic Buin-Zahra earthquake of September 1st, 1962. The Buin-Zahra earthquake destroyed 91 villages in the area entirely and caused the death of 12200 persons. In total, more than 300 villages were damaged or destroyed. In 180 villages, considerable damages and mortalities was reported. The Buin-Zahra earthquake was associated with a fault continued inconsistently from the west of Ipak to the nearby of Ilderchin in a distance about 80km with 130 North to West direction. The magnitude of Buin-Zahra earthquake was 7.2 in Richter scale.
