Extended Nucleation of the 1999 Mw 7.6 Izmit Earthquake
Michel Bouchon,Hayrullah Karabulut,Mustafa Aktar,Serdar Özalaybey,Jean Schmittbuhl,Marie-Paule Bouin +5 more
TL;DR: Observations show that one of the best-recorded large earthquakes to date, the 1999 moment magnitude 7.6 Izmit (Turkey) earthquake, was preceded by a seismic signal of long duration that originated from the hypocenter that consisted of a succession of repetitive seismic bursts, accelerating with time, and increased low-frequency seismic noise.
Journal ArticleDOI
A shallow fault-zone structure illuminated by trapped waves in the Karadere–Duzce branch of the North Anatolian Fault, western Turkey
Yehuda Ben-Zion,Zhigang Peng,David Okaya,Leonardo Seeber,John G. Armbruster,Naşide Özer,Andrew J. Michael,Serif Baris,Mustafa Aktar +8 more
TL;DR: In this paper, the authors discuss the subsurface structure of the Karadere-Duzce branch of the North Anatolian Fault based on analysis of a large seismic data set recorded by a local PASSCAL network in the 6 months following the Mw = 7.4 1999 Izmit earthquake.
Journal ArticleDOI
Space and Time Evolution of Rupture and Faulting during the 1999 İzmit (Turkey) Earthquake
Michel Bouchon,M. Nafi Toksöz,Hayrullah Karabulut,Marie-Paule Bouin,Michel Dietrich,Mustafa Aktar,Margaret Edie +6 more
TL;DR: In this article, the authors used the records of the ground motion obtained at near-fault accelerometers to study the space and time evolution of rupture and faulting during the Izmit earthquake.
Journal ArticleDOI
The 1999 İzmit Earthquake Sequence in Turkey: Seismological and Tectonic Aspects
TL;DR: In this paper, the authors show that the Yalova cluster was triggered by the mainshock and infer that dynamic extensional strains played a major role in triggering this cluster.
Journal ArticleDOI
The seismotectonics of the Marmara region (Turkey): results from a microseismic experiment
Cemil Gurbuz,Mustafa Aktar,Mustafa Aktar,Haluk Eyidogan,A. Cisternas,H. Haessler,Aykut Barka,Mehmet Ergin,Niyazi Türkelli,Orhan Polat,S.B. Üçer,Sadi Kuleli,Serif Baris,Bülent Kaypak,Tolga Bekler,Ekrem Zor,F. Bicmen,A. Yoruk +17 more
TL;DR: In this article, the authors presented a synthesis of recent studies of active tectonics in the region, including inland and underwater observations, in order to have a critical appraisal of the existence of large seismic gaps in the central and eastern Marmara Sea.
