  10. WAVEFORM DATA DISTRUBITION Our waveform data is open publicly. Anyone can connect to the login page using http://barbar.koeri.boun.edu.tr/sismo/zKDRS/login.asp link 2nd NEAMTWS Task Team Meeting30 September-1 October 2008, Southampton, UK

  11. THE APPLICATION OF SEISAN SEISMIC PACKAGE AND ARISEN PROBLEMS TO ROUTINE OBSERVATIONS OR DATA PROCESSING IN KANDILLI OBSERVATORY KOSEOGLU KUSMEZER A. Bogazici University, Kandilli Observatory and Earthquake Research Institute, Istanbul, Turkey 2nd NEAMTWS Task Team Meeting30 September-1 October 2008, Southampton, UK

  12. GEOLOGIC AND TECTONIC SETTINGS The western part of the NAF zone across the Marmara Sea is shown in bathymetric and topographic map. Main active faults are plotted as bold lines. (X Le Pichon 2001) 2nd NEAMTWS Task Team Meeting30 September-1 October 2008, Southampton, UK

  13. SEISMICITY OF THE REGION Seismicity of the Marmara Region between 2000-2007. Explosions are extracted from data. 2nd NEAMTWS Task Team Meeting30 September-1 October 2008, Southampton, UK

  14. SEISMIC STATIONS Green indicates Short Period and Black signs show Broadband Stations in Marmara Region 2nd NEAMTWS Task Team Meeting30 September-1 October 2008, Southampton, UK

  15. WHY SEISAN • It includes most useful packages and analysis tools for seismologists, • User friendly programs, • Allows to archive data in parametric and/or waveform formats for easy retrieval and processing, • Allows determination of different magnitude scaling systems, • It is open source, therefore the package can be modified for any needs. 2nd NEAMTWS Task Team Meeting30 September-1 October 2008, Southampton, UK

  16. OUR OBJECTIVES FOR USING SEISAN • Expected big earthquake in Marmara Region • Magnitude saturation problem, • Mo is influential especially earthquakes between 4.5<M<9.0 • Enables to digitally analysis for big earthquakes • Allows us to compare Moment Tensor Inversion solutions. 2nd NEAMTWS Task Team Meeting30 September-1 October 2008, Southampton, UK
