  Spatial and temporal analysis of current seismic quiescence in the east anatolian fault zone, Eastern Part of Turkey

  Öztürk, S.; Sariçiçek, I.

  In the scope of this study, an evaluation of recent seismic quiescence in the East Anatolian Fault Zone, eastern part of Turkey, is made by using the standard deviate Z-value. For this purpose, a statistical assessment of the spatial and temporal variations of the seismicity rate changes in the beginning of 2013is performed by using ZMAP software package. Results show that four areas with an apparently seismic quiescence may be important in the East Anatolian Fault Zone in the beginning of 2013. These anomalies are observed centered at 39.48°N-39.712°E (between Ovacik and Pülümür, Tunceli), the second one is found centered at 39.06°N-40.297°E (including Karakoçan, Sancak-Uzunpinar and Göynük fault zones), the third one is found centered at 38.55°N-38.763°E (between Malatya fault and EAFZ, north of Pötürge, Malatya) and the last one is found centered as 39.95°N-35.647°E (between Ceyhan-Yumurtalik-Karatas, Adana). The beginnings of these seismic quiescence anomalies are recently observed and nearly started in the beginning of 2007.For this reason, special attention should be given to these regions where the seismic quiescence is observed.

  Imaging of the deteriorations and concrete quality of the tunnels (Zigina, Torul) with ground penetrating radar

  Saricicek, Isil; Seren, Aysel

  Ground Penetrating Radar (GPR) that give high resolution image and no damage to the researched surface, holds an important place in the use of near surface shallow researches. In this study; it is aim to investigate the fracture-crack system, the stratigraphy and the deterioration of the walls of Zigana Tunnel which is located at the way Trabzon-Gümüşhane in order to evaluate the existence of risk area leaking water out and structure contents. Furthermore, in addition to Zigana tunnel, the concrete quality of the Torul tunnel which has built recently was investigated. During examinations, GPR data were collected along totally 20 profiles at the entrance of the both sides of tunnels by using 500 MHz and 800 MHz shielded antennas. After applying data processing stages to the collected data, 2D and 3D images were acquired and interpreted.
