1911 Kebin Earthquake Shakes Almaty on January 3
An earthquake registering 7.7 Mw destroyed Almaty in Russian Turkestan.
On January 3, 1911 a strong earthquake hit Russian Turkestan, leveling much of Almaty. The quake’s magnitude and the damage it caused marked one of the region’s deadliest natural disasters.
The quake and its immediate impact
The earthquake registered a moment magnitude of 7.7 Mw and struck the valley areas of Chon‑Kemin, Chilik and Chon‑Aksu. In Almaty, more than 770 buildings were destroyed and 452 people lost their lives.
The shaking produced about 125 miles (201 km) of surface faulting across the surrounding valleys, a clear sign of the fault’s length and the energy released.
Why the magnitude matters
Moment magnitude (Mw) measures the total energy an earthquake releases, using a logarithmic scale similar to the older Richter scale. An Mw of 7.7 indicates a very large release of energy, enough to cause widespread structural collapse.
Because the scale is based on seismic moment, it provides a consistent way to compare earthquakes of different sizes, even when local magnitude readings differ.
Almaty and Russian Turkestan in 1911
At the time, Almaty (then part of Russian Turkestan) was a growing city in the foothills of the Trans‑Ili Alatau mountains. The region was administered as a Krai of the Russian Empire and was home to speakers of Russian, Uzbek, Kazakh, Kyrgyz and Tajik.
The disaster highlighted the vulnerability of a rapidly expanding urban center situated near active fault lines, influencing later building practices in the area.
Key facts
- Date: January 3, 1911

Frequently asked questions
What is the difference between Mw and the Richter scale?
Mw measures the total seismic energy released, while the Richter scale estimates amplitude of seismic waves; both use logarithmic scales but Mw is more consistent for large quakes.
How did the 1911 quake affect Almaty's development?
The destruction forced reconstruction with greater attention to seismic safety, shaping building codes and urban planning in the growing city.
