Abstract

Uncertainty in the determination of fault locking depth and strike slip rates by GNSS measurements

Highlights

  • Today, measurements from global navigation satellite systems (GNSS) are accurate enough for geodetic and geophysics research, ranging from defining short-time crustal movements to regular inter-seismic deformations of plate movements [11, 17]

  • This study examines the effects of GNSS velocities derived from different datum definitions on fault locking depth and strike-slip rates, the parameters of elastic rebound theory

  • The comparison of results obtained from six different solutions in fault locking depths and strike slip rates in eastern part of North Anatolian Fault Zone (NAFZ) can be seen in Tab. 4

Summary

Poyraz

Original scientific paper A GNSS network of 36 points was established in 2006 in the eastern part of the North Anatolian Fault Zone, which is located between Tokat and Erzincan. This study compares GNSS velocities estimated with different datum definitions and the effects on fault locking depth and strike-slip rates, which are parameters of elastic rebound theory. These two parameters contain preliminary information on possible earthquakes in the region. GNSS mjerenja su obavljena 2006 ÷ 2008 u dolini Kelkit te su izračunate brzine tih točaka. U ovoj se analizi uspoređuju GNSS brzine dobivene različitim definicijama podatka i učinaka na dubinu zaustavljanja rasjeda i brzine horizontalnog kretanja, što su parametri teorije elastičnog odboja (elastic rebound theory). Ključne riječi: brzine horizontalnog kretanja; dubina zaustavljanja; GNSS (globalni navigacijski satelitski sustav); zona rasjeda sjeverne Anatolije
