The M-w=7.4 earthquake that affected the northwestern part of Turkey oil August 17, 1999, and in particular the gulf of Izmit, had dramatic consequences also as regards tsunami generation. The main cause of the earthquake was a dextral strike-slip rupture that took place along different segments of the western part of the North Anatolian Fault (WNAF). The rupture process involved not only a number of distinct strike-slip fault segments, but also dip-slip ancillary faults, connecting the main transcurrent segments. The general picture was further complicated by the occurrence of subsidence and liquefaction phenomena, especially along the coasts of the Izmit bay and in the Sapanca Lake. Tsunami effects were observed and measured during post-event surveys in several places along both the northern and the southern coasts of the bay. The run-up heights in most places were reported to lie in the interval 1-3 m: but in the small town of Degirmendere, where a local slump occurred carrying underwater buildings and gardens of the waterfront sector, eyewitnesses reported water waves higher than 15 m.

A critical examination of near-field accelerograms from the sea of Marmara region earthquakes
Akkar, S; Gulkan, P (Seismological Society of America (SSA), 2002-02-01)
In 1999, Turkey was struck by two major earthquakes that occurred 86 days apart on the North Anatolian Fault system. Both earthquakes had right-lateral strike-slip mechanisms with moment magnitudes greater than 7. The number of strong-motion records obtained from the Kocaeli earthquake (17 August 1999, M-w 7.4) was 34. The second event, designated as the Bolu-Duzce earthquake (12 November 1999, M-w 7.2), triggered 20 instruments. Among the records that we have from these earthquakes, seven are from near-sou...
The Chios, Greece Earthquake of 23 July 1949: Seismological Reassessment and Tsunami Investigations
Melis, Nikolaos S.; Okal, Emile A.; Synolakis, Costas E.; Kalogeras, Ioannis S.; Kanoğlu, Utku (Springer Science and Business Media LLC, 2020-03-01)
We present a modern seismological reassessment of the Chios earthquake of 23 July 1949, one of the largest in the Central Aegean Sea. We relocate the event to the basin separating Chios and Lesvos, and confirm a normal faulting mechanism generally comparable to that of the recent Lesvos earthquake located at the Northern end of that basin. The seismic moment obtained from mantle surface waves, M-0=7x10(26) dyn cm, makes it second only to the 1956 Amorgos earthquake. We compile all available macroseismic dat...
The 2002 Denali fault and 2001 Kunlun fault earthquakes: Complex rupture processes of two large strike-slip events
Özacar, Atilla Arda (Seismological Society of America (SSA), 2004-12-01)
We studied the source processes of two large continental earthquakes, the 3 November 2002 Denali fault earthquake and the 14 November 2001 Kunlun fault earthquake, associated with strike-slip faulting along ancient sutures. We inverted teleseismic P waveforms using a pulse-stripping method for multiple time windows with different focal mechanisms and derived composite source models. According to our results, the 2002 Denali fault earthquake began with initial thrusting (M-W 7.3) along a 40-km-long segment o...
An overview of local site effects and the associated building damage in Adapazari during the 17 August 1999 Izmit earthquake
Bakır, Bahadır Sadık; Sucuoğlu, Haluk (Seismological Society of America (SSA), 2002-02-01)
Two major earthquakes occurred in Turkey along the North Anatolian fault in 1999. The first one, which occurred on 17 August 1999, had a moment magnitude of 7.4 and ruptured the 140-km segment of the fault in the Marmara region. Adapazari, a city with a population of 190,000, which is mostly located on a deep alluvial basin in the near field of the ruptured fault, was among the worst-affected urban areas in the earthquake-affected region. The distribution of damage over the city was highly nonuniform, indic...
The 20th July 2017 Bodrum-Kos Tsunami Field Survey
Dogan, Gozde Guney; Annunziato, Alessandro; Papadopoulos, Gerassimos A.; GÜLER, HASAN GÖKHAN; Yalçıner, Ahmet Cevdet; Cakir, Tarik Eray; Sozdinler, Ceren Ozer; ULUTAŞ, ERGİN; Arikawa, Taro; Süzen, Mehmet Lütfi; Guler, Isikhan; Probst, Pamela; Kanoğlu, Utku; Synolakis, Costas (Springer Science and Business Media LLC, 2019-07-01)
The July 20, 2017 Bodrum-Kos Earthquake caused tsunami wave motions and damage in the south of Bodrum Peninsula, Turkey, and on Kos Island, Greece. Immediately after the earthquake, we conducted several post-tsunami field surveys including interviews in coastal zones impacted by the tsunami, i.e., the coastlines of Bodrum Peninsula, Karaada Islet and Akyaka Town in Gokova Bay, Turkey, and eastern Kos Island, Greece. We present observations and measurements to document the variation of the tsunami effects al...
