More than 30 tsunami events have impacted the coasts of the Sea of Marmara in the past two millennium, clustering in Izmit Bay, the shores of istanbul, Gemlik Bay, the shores of the Kapidak and Gelibolu Peninsulas. With respect to the last well-known tsunami, the Izmit tsunami of 17 August, 1999, available field survey run-up data and marine surveys provide an opportunity to evaluate how these events were triggered. The main purpose of this study is to determine the slope failure potential as a possible tsunamigenic source in the Sea of Marmara by utilising multi-beam bathymetry, shallow and deep seismic reflection data. On the basis of the landslide geomorphology, the generation, propagation and coastal amplifications of tsunamis related to earthquake and slope failure scenarios were tested by using tsunami simulation model TWO-LAYER. The maximum water surface elevations near the shores along the north and south coasts are obtained according to the selected scenarios of tsunami generation by using available data.

Volcano stratigraphy and petrogenesis of the Nemrut stratovolcano (East Anatolian High Plateau): The most recent post-collisional volcanism in Turkey Ozdemir, Y; Karaoglu, O; Tolluoglu, AO; Güleç, Nilgün Türkan (Elsevier BV, 2006-02-28) The Nemrut stratovolcano, with its well defined summit caldera, is the most recent volcanic eruption center (1441 A.D.) in the East Anatolian High Plateau, one of the best examples of an active colllision zone. Widespread volcanism has been active in this region for the last similar to 10 Ma, producing large volumes of lavas and pyroelastics covering a broad belt, across the Bitlis Suture Zone, from the Anatolian plate in the north to the Arabian plate in the south.
Historical and pre-historical tsunamis in the Mediterranean and its connected seas: Geological signatures, generation mechanisms and coastal impacts Papadopoulos, Gerassimos A.; Gracia, Eulalia; Urgeles, Roger; Sallares, Valenti; De Martini, Paolo Marco; Pantosti, Daniela; Gonzalez, Mauricio; Yalçıner, Ahmet Cevdet; Mascle, Jean; Sakellariou, Dimitris; Salamon, Amos; Tinti, Stefano; Karastathis, Vassilis; Fokaefs, Anna; Camerlenghi, Angelo; Novikova, Tatyana; Papageorgiou, Antonia (Elsevier BV, 2014-08-01) The origin of tsunamis in the Mediterranean region and its connected seas, including the Marmara Sea, the Black Sea and the SW Iberian Margin in the NE Atlantic Ocean, is reviewed within the geological and seismotectonic settings of the region. A variety of historical documentary sources combined with evidence from onshore and offshore geological signatures, geomorphological imprints, observations from selected coastal archeological sites, as well as instrumental records, eyewitnesses accounts and pictorial...
Sub-ophiolite metamorphic rocks from NW Anatolia, Turkey Onen, AP; Hall, R (Wiley, 2000-09-01) The metamorphic rocks from near Kutahya in north-west Anatolia record different stages in the history of closure of the Neo-Tethyan Izmir-Ankara-Erzincan ocean. Sub-ophiolite metamorphic rocks within the Tavsanli zone are a tectonically composite sequence of quartz-mica schists, amphibole schists, amphibolites and garnet amphibolites. They show increasing metamorphic grade towards the base of the ophiolite. A first metamorphic event, typical of sub-ophiolite metamorphic sole rocks, was characterized by high...
SEISMIC STRATIGRAPHY OF THE FAULT-CONTROLLED SUBMARINE-CANYON VALLEY SYSTEM ON THE SHELF AND UPPER SLOPE OF ANAMUR BAY, NORTHEASTERN MEDITERRANEAN-SEA EDIGER, V; OKYAR, M; ERGIN, M (Elsevier BV, 1993-11-01) High-resolution shallow seismic reflection (Uniboom) and echosounding profiles obtained on the shelf and upper slope areas of Anamur Bay (Turkey, northeastern Mediterranean) were studied together with previous data on the onshore geology of the area to investigate the origin and related seismic stratigraphy of the submarine Anamur Canyon. It was found that the main axial trend of the submarine Anamur Canyon is aligned with the offshore projection of the N-S orientated, onshore Anamur thrust fault of Late Cr...
Seismic stratigraphy of Late Quaternary sediments of western Mersin Bay shelf, (NE Mediterranean Sea) Okyar, M; Ergin, M; Evans, G (Elsevier BV, 2005-10-15) High-resolution shallow seismic-reflection profiles obtained from the western Mersin Bay have revealed the existence of the two distinct depositional sequences (C and B) lying on a narrow and relatively steeply-sloping continental shelf which mainly receives its sediments from the ephemeral rivers. The upper Holocene sedimentary sequence (C) is characterized by stratified (simple to complex) to chaotic reflection configurations produced by the development of a prograding wedge of terrigenous sediment.
