A global approach to provide magnitude estimates for earthquake early warning alerts

Küyük, Hüseyin Serdar; Richard M. Allen (AMER GEOPHYSICAL UNION, 2013)

We examine five different methods to estimate an earthquake's magnitude using only P wave data for use in earthquake early warning systems. We test two input parameters: the maximum predominant period of the P wave ((max)(p)) ...
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 ...
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 ...
Automatic earthquake confirmation for early warning system

Küyük, Hüseyin Serdar; S. Colombelli; A. Zollo; R. M. Allen; M. O. Erdik (AMER GEOPHYSICAL UNION, 2015)

Earthquake early warning studies are shifting real-time seismology in earthquake science. They provide methods to rapidly assess earthquakes to predict damaging ground shaking. Preventing false alarms from these systems ...
Clustering Seismic Activities Using Linear and Nonlinear Discriminant Analysis

Küyük, Hüseyin Serdar; Yıldırım, Eray; Doğan, Emrah; Horasan, Gündüz (388 LIMO RD, WUHAN, CHINA MAINLAND 430074, PEOPLES R CHINA, 2014)

Identification and classification of different seismo-tectonic events with similar characteristics in a region of interest is one of the most important subjects in seismic hazard studies. In this study, linear and nonlinear ...
Designing a Network-Based Earthquake Early Warning Algorithm for California: ElarmS-2

Küyük, Hüseyin Serdar; Richard M. Allen; Holly Brown; Margaret Hellweg; Ivan Henson; Douglas Neuhauser (SEISMOLOGICAL SOC AMER, 2014)

The California Integrated Seismic Network (CISN) is developing an earthquake early warning (EEW) demonstration system for the state of California. Within this CISN ShakeAlert project, three algorithms are being tested, one ...
Earthquake Preparedness Strategies for Telecom Backbone with Integration of Early Warning Systems and Optical WDM Networks (Invited Paper)

Dikbıyık, Ferhat; Küyük, Hüseyin Serdar (IEEE, 2016)

In this study, we explore three different strategies for such situation; 1) Extreme approach that reprovisions all connections in danger with full or degraded bandwidth, 2) relax approach that reprovisions only critical ...
Efficiency of wave impeding barrier in pipeline construction under earthquake excitation using nonlinear finite element analysis

Göktepe, Fatih; Küyük, Hüseyin Serdar; Çelebi, Erkan (SPRINGER INDIA, 2014)

Earthquakes have caused colossal casualties and severe damages to engineering structures and especially leading to substantial economic loss to the underground structures and/or infrastructures. Pipelines are one of most ...
In-situ Experiment on Dynamic Soil-Structure Interaction

Göktepe, Fatih; Çelebi, Erkan; Küyük, Hüseyin Serdar (GAZI UNIV, 2017)

The traditional methods utilized in today's seismic design of structures involve structure's foundation as a fixed base by assuming soil does not deforms. Earthquake input motion is also considered as a horizontal movement ...
On the use of Stockwell transform in structural dynamic analysis

Küyük, Hüseyin Serdar (INDIAN ACAD SCIENCES, 2015)

Time-frequency analysis of earthquake records using Fourier transform is a fundamental, reliable and useful tool in earthquake engineering and engineering seismology. It will be however no longer functional if the frequency ...
Optimal Seismic Network Density for Earthquake Early Warning: A Case Study from California

Küyük, Hüseyin Serdar (SEISMOLOGICAL SOC AMER, 2013)
