Abstract

Two individuals of pompano, Trachinotus ovatus (Linnaeus, 1758), were captured in Filburnu Bay (İstanbul Strait), representing a new record for the fish fauna of the Turkısh Straıts System. Occurrence of this thermophilic species is presumably related to the increased seawater temperatures in the region.

Abstract

Following the Kocaeli Earthquake (17 August 1999), the seismic reflection profiles gathered in the Gemlik Bay in 1984 were reinterpreted in order to identify the characteristics of the sedimentary depositional environments and their relations with the tectonic setting. A discussion followed about the implications for seismic hazard assessment in the Gemlik Bay region.

Abstract

In the present study, coastal field observations, detailed bathymetric data and analyses of single-channel, high resolution seismic reflection data are used to characterise tsunami generated during the Kocaeli Earthquake (August, 17^th 1999) in the Izmit Bay.

Abstract

The fault rupture of the Kocaeli Earthquake ( M_W  7.4, at 03:02 on August 17^th, 1999) was well defined on land. In the present study, single-channel, high resolution seismic reflection data were used to characterise the underwater fault signatures of the Kocaeli Earthquake in the Izmit Bay and at the eastern Marmara Sea. Some personal opinions are also given about the speculations for a possible (<30 years) and devastating (>magnitude 8) earthquake in the Marmara Sea.
