Seismic monitoring
Geographically Kyrgyzstan is located in the limits of the Tien-Shan orogen, the modern tectonic activity of which defines a high seismicity of this territory. Very strong earthquakes with magnitude up to 8 and a lot of weaker events occur here. In average we process about seven thousand earthquakes per year. That is why a seismic monitoring was and remains one of the most actual problems for our republic.

Developmental stages of Kyrgyz System of Seismic Monitoring
The instrumental seismic observations in Kyrgyzstan have begun since on the base of analogue stations that essentially influenced on the network efficiency.
In October, 1990 the first digital broad-band seismic station AAK10 has been installed on the Kyrgyz territory as observation point of Global Seismographic Network IRIS/IDA. This seismic station is included into IMS CTBTO as a 3C auxiliary station AS060.
Since 1991 the telemetry network KNET consisting of 10 stations, equipped with broad-band high-sensitive devices has begun its operation here.
In 2007, within the frame of CTBT capacity building, NORSAR, with support from the Ministry of Foreign Affairs of Norway, provided the Kyrgyz Institute of Seismology with 10 digital broad-band stations, most of which have been installed in the south of Kyrgyzstan characterized by the high level of seismic activity.
In 2009 the new seismic network has been registered in FDSN as KRNET (Kyrgyz Republic Digital Network). At present it consists of 16 broad-band stations located on all territory of Kyrgyzstan. Moreover under IRIS support the real time data of 13 KRNET stations are openly accessible at the IRIS–DMC website.
Nowadays the Kyrgyz system of seismic monitoring includes 10 KNET stations and 16 KRNET stations, otherwise 26 seismic stations.

Data transmission and exchange
AAK (AS060) waveforms in real time mode are sending to the IDC CTBTO.
KRNET waveforms in real time mode are sending to the IRIS/DMC.
Since 2011 both preliminary and final bulletins of KRNET data are sending to the ISC.
