Overviewon Seismicityof Turkey
The majority of the population (72 %) live in seismically active areas.
Eurasian Plate
Anatolian
Block

Due to on the interaction among the Arabian, Africanand Eurasian tectonic plates, a wedge-shaped
continental crust known as the Anatolian block wasformed.

African Plate
The movement on the wedge takes place on two major strike-slip faults:
 The 1500-km long North Anatolian Fault Zone (NAFZ), The 550-km long East Anatolian Fault Zone (EAFZ).

Overview on Seismicity of Turkey

TR-NSMN was established in 1973 with 67 analog recorders.

All the accelerographs are located on thefree surface in densely populated cities in
active regions such as NAFZ, EAFZ and theAegean Graben Systems.

TR-NSMN with 678 stations in total consists of 3 different digital tri-axial force-balance accelerometers of CMG5TD (24 bit) at 338 stations, SARA (24 bit) at 115 stations, GSR (16/18 bit) at 8 stations, and GMSplus (24 bit) at217 stations.
Data transmission is provided via dial-up, ADSL, GPRS EDGE (mostly) and satellite.

 The Japan Meteorological Agency (JMA) Seismic Intensity Network, 180 seismographs and600 seismic intensity meters.
 K (Kyoshin) –Net ( > 1000 stations) and KiK (Kiban Kyoshin)-net ( >700 stations) Seismic Intensity Information Network of Local Governments
 About 200 JMA stations and 500 K-Net stations have been already placed, 2600 seismic
intensity meters were newly installed.

Conclusionan Recommendations
 History of strong motion observation reaches a half of a century in Turkey and The observation density
has been extremely getting higher.
 Characteristics of recent strong motion instruments and observation work in Japan can besummarized as follows: Calculation and display of seismic intensity scale and/or spectral intensity, Prompt transmittance and announcement of seismic information,
 Prompt transmittance and announcement of seismic information,
 Rapid publication of digital acceleration data.
In the light of this information; it is suggested that TR-NSMN should be developed as in the case of Japan.
More reinforcement of the strong motion observation targeted at building structures is earnestly expected.
