The 2003 Altai earthquake, or 2003 Chuya earthquake, occurred on September 27 at 18:33:26 local time with a moment magnitude of 7.3 and a maximum Mercalli intensity of X (Extreme). The epicenter of this oblique-slip shock was in Altai Republic, Russia near the borders of Mongolia, China, and Kazakhstan. Three deaths and five injuries were reported and the total damage was listed as $10.6–33 million.
Earthquake
[edit]This earthquake had components of right-lateral strike-slip and reverse movement in a segmented fault zone which had not been previously recognized.[5]
Damage
[edit]Between 99 and 300 houses destroyed, along with 1,942 other buildings affected. It was the strongest earthquake in this region since an estimated magnitude 7.7 earthquake on December 20, 1761.[3][4]
Ground effects
[edit]Landslides affected the Kosh-Agachsky and Ust'-Ulagan Districts.[4]
