Earthquake

The territory of Kyrgyzstan is one of the most seismically active regions on the planet where there are up to 1,500 tremors a year of varying strength. High seismic activity is due to tectonic processes and complex geological and tectonic setting.
In the historical memory of the people, first information about the catastrophic disaster are the days when in the valley of Chon-Kemin river an ancient city was completely destroyed (the name of which is not known). More specific data refers to the end of the XVIII century (in 1770 "a lake was filled up" near Belovodsk) and in the beginning of the next century (in 1807 in Almaty, there was a "terrible accident, which echoed all the way into Kyrgyzstan).
Detailed systematic information on earthquakes begins with a description of the Belovodsk disaster in 1885 (magnitude 9-10 ). The earthquake completely destroyed Belovodsk and Kara-Balta villages; on the slopes of the Kyrgyz ridge were rock falls, landslides, and debris, and a crack of 20 km long and 2 m wide developed in the foothills.
In 1911, in the North Tenir-Too there was a great seismic disaster (Kemin earthquake measuring magnitude 10-11), which killed more than 1,500 people. The length of large-scale violations of the earth's surface (cracks, collapses, landslides, etc.) reached 250 km.
In June 1938, there was an earthquake with the strength of aftershocks up to magnitude 8 with an epicentre near Jel-Arik station (eastern extremity of the Chu basin). The Chatkal earthquake in 1946 measuring 9-10 seized a huge area. Settlements located in the epi-central area were turned into rubble (stretching up to 100 km long, 15-20 km wide); in the valleys and foothill areas significant falls and breakdowns occurred. Large cracks opened up, where part of Sary-Chelek lake was blocked by rubble.

In 1970, in the eastern part of the Issyk-Kul basin, Sarykamysh earthquake occurred measuring magnitude 8-9 . By the size of the hearth and the released energy, it is the largest earthquake on the northern slopes of Teskey Ala-Too ridge. The zone of maximum shock (20x10 km). There was massive avalanches, landslides and rock falls observed in the mountains.

In 1978, Tyup earthquake occurred with its intensity in the epicentre reaching 8-9. More than 50 settlements of Tyup area were damaged and destroyed.

In 1977, on the territory of Batken district of Osh region (south-eastern part of the Fergana Valley) was an earthquake of magnitude 8-9, which was felt by a large part of Kyrgyzstan, Uzbekistan and Tajikistan, as well as in the south-western regions of Kazakhstan.
Earthquake (8-9) occurred in the south-western part of the Alay basin, which is marked as Daroot-Korgon.
In May 1992, in the south of Kyrgyzstan a Kochkor-Ata earthquake occurred (on the scale of 7-8). The epi-central area extended up to 40 km in length and 5-7 km in width.

One of the strongest earthquakes in recent years was Suusamyr (August 1992), which covered the territory from the Kazakh steppes to the North Pamir in the south. The zone of maximum shock covered the southern and northern slopes of Suusamyr ridge, Suusamyr, Aramzin, Ketmen-Teben and Talas basins. All settlements within its proximity were destroyed by 60-80%. Avalanches and landslides in the mountains led to the loss of life and destruction of numerous animals.
In January 1997, in the mountains of Jaman-Davan of Naryn region, a magnitude 7-7.5 earthquake was registered, which was felt throughout the territory of northern Tenir-Too. Top
