An unsupervised learning algorithm: application to the discrimination of seismic events and quarry blasts in the vicinity of Istanbul

Küyük, Hüseyin Serdar; Yıldırım, Eray; Doğan, Emrah; Horasan, Gündüz; Yıldırım, Engin (COPERNICUS GESELLSCHAFT MBH, 2011)

The results of the application of an unsupervised learning (neural network) approach comprising a Self Organizing Map (SOM), to distinguish micro-earthquakes from quarry blasts in the vicinity of Istanbul, Turkey, are ...
Analysis of strong ground motion data from the Van earthquake (Turkey), 2011

Beyhan, Günay; Keskinsezer, Ayhan; Ozkan Kafadar (SPRINGER HEIDELBERG, 2019)

An earthquake of magnitude 6.6 (ML) and 7.2 (Mw) occurred at 13: 41 p.m. local time on October 23, 2011 in the western of the Ercek Lake and about 20 km away from the city center of Van, Turkey (EQE-KOERI in The October ...
Application of k-means and Gaussian mixture model for classification of seismic activities in Istanbul

Küyük, Hüseyin Serdar; Yıldırım, Eray; Doğan, Emrah; Horasan, Gündüz (COPERNICUS GESELLSCHAFT MBH, 2012)

Two unsupervised pattern recognition algorithms, k-means, and Gaussian mixture model (GMM) analyses have been applied to classify seismic events in the vicinity of Istanbul. Earthquakes, which are occurring at different ...
Assessment of geothermal energy potential by geophysical methods: Nevsehir Region, Central Anatolia

Kıyak, Alper; Karavul, Can; Gülen, Levent; Ertan Peksen; A. Riza Kilic (ELSEVIER SCIENCE BV, 2015)

In this study, geothermal potential of the Nevsehir region (Central Anatolia) was assessed by using vertical electrical sounding (VES), self-potential (SP), magnetotelluric (MT), gravity and gravity 3D Euler deconvolution ...
Bala (Ankara) Earthquakes: Implications for Shallow Crustal Deformation in Central Anatolian Section of the Anatolian Platelet (Turkey)

Saatçılar, Ruhi (SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2010)

Central Anatolia is quiet in terms of seismic activity, and rarely earthquakes up to magnitude 5.6 occur in the inner part of the Anatolian block or Anatolian platelet. Southeast of Ankara, the capital city of Turkey, two ...
Buried underground archaeological structures investigation with electrical method: diyarbakir Ulu Mosque (Turkey)

Karavul, Can; Nihan Arig; T. Fikret Kurnaz; Demirkol, Aşkın (NATL INST OPTOELECTRONICS, 2015)
