Active Tectonics, Seismology, Seismotectonics and Geodynamics Research
within the Geophysics, Earth Physics area has broad interests ranging from waveform modelling for earthquake source studies, to elucidating lithospheric structures, to studying earthquake induced tsunamis, to developing new methods for imaging Earth's interior. The research group covers a range of activities designed to exploit the favourable location of Turkey relative to the world's active earthquake belts. This is reflected in studies using deployments of portable instrumentation to study the structure of the Anatolian continent and the mantle beneath. Research in different topics of earthquake source studies, theoretical and computational seismology are strengths of the group.

Earthquake Source Mechanisms: We study the physical processes of earthquakes. As it is widely known a better understanding of the earthquake source contributes to evaluations of earthquake damage and efforts in earthquake prediction. We analyze seismic waveforms, crustal deformations, and other geophysical data in order to investigate physical mechanisms of the earthquake source.

Seismotectonics: Using methods from a variety of geophysical fields, such as seismology and geodesy among other fields, inhomogeneities in the Earth’s crust, earthquake source mechanisms, and earthquake preparation processes are investigated to improve the understanding and evaluation of long-term earthquake occurrences. In particular, studies are conducted to investigate the heterogeneous structures in the regions of the subduction plate boundary and the lower crust of inland areas. The results of these studies help clarify the regional stress accumulation process.

Computational Seismology: High Resolution Seismic Imaging Adjoint Techniques are performed in order to resolve complexities of crustal and lithospheric structures. Furthermore, Plate-Scale seismological mapping of the Anatolia is currently being extensively studied.

Multidisciplinary Constrains on the Physical State of the Lithosphere and Asthenosphere: One of the dreams of geoscience is to connect deep structures to surface processes. To achieve this, one must understand the forces driving, and the strengths resisting, deformation. Since these forces and strengths are primarily driven by density, temperature, and composition (including volatiles), it becomes imperative to move from seismological maps of red and blue regions to maps of physical state. However, a range of phenomena can produce similar observations; for instance, melting and temperature increases can both produce similar changes in seismic velocities. Hence, a range of observables must be combined--carefully--to properly assess the range of physical state variations that fit the data.
