Karabacak et al. have published a study of the surface creep along the North Anatolian Fault in the EPSL. They used a ground-based light detection and ranging (LIDAR) system on an unreported site where three manmade walls across the fault were monitored for 3 yrs between 2007 and 2009. They found that 50–70% of the yearly slip accumulates on the faults creep section. Please find more info here doi:10.1016/j.epsl.2011.01.017

Last 6000 years climate record from Tecer Lake in central Turkey were published in Holoceneby Kuzucuoğlu et al. According to the mineralogy and grain-size distribution of lake sediments, during the mid-Holocene transition, intense droughts occured at the end of the sixth, fifth and fourth millennia BP. The characteristics of some climatic phases at Tecer seem specific to the location of the sequence which, when compared with other sites in the eastern Mediterranean, may record variations in the extent of different climatic systems.

Kose et al. 2011 have published a new data set on May-June precipitation of the Late Holocene obtained from 17 black pine tree-rings. Their study was published in the Journal of Quaternary Research. May–June precipitation reconstructions contain mostly one-year and, less commonly, two-year drought events. The longest consecutive dry period was in between 1925–1928 AD. The driest year was 1887. The wettest years for the entire western Anatolia were determined to be AD 1835, 1876, 1881 and 1901. They claimed that the study provides a better understanding of agricultural drought and management of regional water resources.

Uysal et al. 2011 have published a new study about long term seismic cycles recorded in southwest Anatolian calcite veins. The study appeared in the Journal of Earth and Planetary Science Letters. They conducted high-resolution micro-sampling, high-precision U-series dating and micro- chemical analysis on an extensional vein system in a tectonically active area. U/Th ages of the vein system is in between 23.9±0.2 ka and 11.8±0.2ka. Their study offers an innovative means of constraining the absolute timing of late Quaternary seismic and inter-seismic events in Anatolia, Turkey.

Muratli Dam on Coruh River (Source: Akpinar et al.)

A new review paper on hydropower energy potential of Turkey has been published by Akpinar et al. in Renewable and Sustainable Energy Reviews. Akpinar et al. investigated the hydropower plants in the Çoruh river basin, in the NorthEastern Turkey. There are total installed 37 dams and run of river (without storage) hydropower plants developed at various project stages, which corresponds 6.3% of total electricity energy production of Turkey.

Solar energy map of Turkey (from Kaygusuz, 2010)

A review on solar energy potential of Turkey is published in the Journal of Renewable and Sustainable Energy Reviews by Dr. Kaygusuz from Karadeniz Technical University. He claimed in the paper that the Concentrating Solar Power (CSP) generation has the potential to become cost-effective energy production of Turkey in the future as the electricity demand of Turkey is rapidly increasing. Turkish government recently supporting the development of this type of technology strongly. For more details please go to doi:10.1016/j.rser.2010.09.042
