    City Of Bingol In May 2003: Assessment Of Strong Ground Motion Records
    (Indian Acad Sciences, 2014) Ceken, U.; Beyhan, G.; Selim, Hamit Haluk
    The main shock of Bingol earthquake (M-w = 6.4) recorded by six accelerometers in the area occurred at 03:27 local time on May 1, 2003. The largest acceleration value of north south component was recorded as 545.5 cm/s(2) at the nearest station which is 12 km away from the epicenter of earthquake. Especially, 0.15 s short period was observed when high spectral acceleration value occurred. An acceleration value greater than 50 gal was recorded at the BNG (Bingol) station and structural damage occurred within 6.5 s was very important for the near source and strong ground motion seismology. The recorded peak acceleration values were greater than the estimated empirical acceleration values. However, the structural damage was not as high and widespread as expected. This occurrence was explained by considering the factors of earthquake source, frequency content, effective duration, effective acceleration value, local soil conditions, rupture direction and attenuation.

    Raised braided stream gravels on Mount Keldağ, Hatay (Eastern Mediterranean coast, Turkey): Implications of transformation to beachrock and ensuing tectonic uplift
    (Springer Science and Business Media B.V., 2019) Erginal, Ahmet Evren; Polymeris, Georgios S.; Karataş, Atilla; Giannoulatou, Valeria; Şahiner, Eren; Meriç, Niyazi; Erenoğlu, Oya; Selim, Hamit Haluk; Karabıyıkoğlu, Mustafa
    On the seaward northwest slopes of Mount Keldağ, Hatay, the combination of an unconformably overlapping sequence of cemented gravels on a wave-cut platform, and a raised notch and irregular pits left by grazing molluscs on the walls of this notch, carved in an NE-trending high-angle fault plane, retain the record of raised braided stream gravels transformed into beachrock. From the OSL ages, this study reveals that deposition of this sequence occurred between 232.30 ± 31.62 and 214.01 ± 27.42 ka during the penultimate interglacial. The four distinct facies identified are massive matrix-supported conglomerate, massive to crudely stratified gravel, cross-stratified gravel, and clast-supported open-work gravel. Extending to the paleo-coastline during the MIS7 highstand, this sequence was cemented by carbonate and iron-oxide cements and records an uplift of around 0.1 mm/year up to the present.
