The 2002 Tbilisi earthquake occurred on April 25 in the Caucasus country of Georgia. The United States' National Earthquake Information Center (NEIC) placed the magnitude at 4.3 Ms and 4.8 mb. This moderate magnitude event resulted in a maximum MSK intensity of VII (Very strong) to VIII (Damaging). An independent investigation estimated the total losses at $160 million (US) while the Centre for Research on the Epidemiology of Disasters estimated the total losses at 350 million. Between five and seven were killed, 52–70 were injured, and more than 1,000 were left homeless.

Tectonic setting

The Greater Caucasus occupy the region between the Black Sea and the Caspian Sea and includes Aremenia, Azerbaijan, Georgia, and the Russian Caucasus. This mountainous region has been forced northward and upward as a result of the Arabian Plate colliding with the Eurasian Plate.[5]
