Since 1st May 2011, the region of Eastern Kazakhstan is experiencing an important seismic activity with more than 8 events of magnitude larger 4.0 in 2 days.

These earthquakes occurred within the Kazakhstan platform, which lies North of the Tien Shan Mountains. The Tien Shan region is a highly seismic area at the boundary between the Tarim bassin and the stable Kazakhstan platform, resulting from the complex Indian plate subduction under the Eurasian plate.
On January 3rd, 1911, the Kebin earthquake of magnitude 8.2 struck the city of Almaty, making 450 victims. It occurred about 100km from the May 1st 2011 earthquake. (source: T. Utsu ; International Handbook of Earthquake and Engineering Seismology; vol. A; 691-718). On June 8th 1887, a similar event of magnitude 7.3 took place.
