Broadband ground motion simulation within Duzce city (Turkey)

Özmen, Ekin
Earthquakes have more hazardous and devastating effects in populated areas. To prevent damage and reduce the risks, broadband records are collected to use in the seismic hazard assessment and engineering seismology. In areas with significant seismic activity and insufficient seismic networks, the simulated ground motions become more important. Broadband ground motion simulations are performed for 12 November 1999 Duzce earthquake. Deterministic simulations are performed for low frequency part and stochastic simulations are performed for high frequency part of the ground motion record. Broadband ground motion simulations are done using EXSIM program for the stochastic high frequency portion of the ground motion and COMPSYN program for the deterministic low frequency portion. The comparisons of the real and simulated ground motion simulations are done in both time and frequency domains. For comparisons, four stations are selected, namely BOL, DZC, GYN and SKR which are located near Duzce City. Comparisons of observed damage with the distribution of simulated ground motion are also given. Additionally, attenuation of simulated data is compared against ground motion prediction equations. Finally, simulated records of the 12 November 1999 Duzce earthquake are used in dynamic response analysis of three selected frames. The responses from simulated data is compared with those from the real data.


Probabilistic seismic hazard assessment for earthquake induced landslides
Balal, Onur; Gülerce, Zeynep; Department of Civil Engineering (2013)
Earthquake-induced slope instability is one of the major sources of earthquake hazards in near fault regions. Simplified tools, such as Newmark’s Sliding Block (NSB) Analysis are widely used to represent the stability of a slope under earthquake shaking. The outcome of this analogy is the slope displacement where larger displacement values indicate higher seismic slope instability risk. Recent studies in the literature propose empirical models between the slope displacement and single or multiple ground mot...
Probabilistic seismic hazard assessment of Ilgaz - Abant segments of North Anatolian fault using improved seismic source models
Levendoğlu, Mert; Gülerce, Zeynep; Department of Civil Engineering (2013)
Bolu-Ilgaz region was damaged by several large earthquakes in the last century and the structural damage was substantial especially after the 1944 and 1999 earthquakes. The objective of this study is to build the seismic source characterization model for the rupture zone of 1944 Bolu-Gerede earthquake and perform probabilistic seismic hazard assessment (PSHA) in the region. One of the major improvements over the previous PSHA practices accomplished in this study is the development of advanced seismic source...
Ground motion simulations based on regional input parameters and their impact on insurance premiums: Bursa case
Ünal, Barış; Askan Gündoğan, Ayşegül; Kestel, Sevtap Ayşe; Department of Earthquake Studies (2015)
Determination of earthquake parameters are required for earthquake resistant design and retrofitting of exsisting structures. There are not many options to obtain earthquake data for regions with no or sparce earthquake recordings. Even though some methods are aplicable to these regions they generate only peak ground motion parameters. For cases that require the full ground motion simulations are necessary. Simulations can also be used for gaining knowledge about source, path and site effects. In this study...
Seismic Intensity Maps for the Eastern Part of the North Anatolian Fault Zone (Turkey) Based on Recorded and Simulated Ground-Motion Data
Askan, Aysegul; Karim Zadeh Naghshineh, Shaghayegh; Bilal, Mustafa (2017-01-01)
Seismic intensity maps are employed globally in the aftermaths of earthquakes for rapid response purposes. These maps involve correlations between intensity and peak ground-motion values. In this study, we focus on eastern sections of the North Anatolian fault zone (NAFZ). The eastern segments of the NAFZ are less investigated and have sparse seismic networks compared with western ones. In particular, we study Erzincan, which is a small city in eastern Turkey, located in the conjunction of three active faul...
Ground motion prediction equations based on simulated ground motions
Gür, Kader; Askan Gündoğan, Ayşegül; Kale, Özkan; Department of Earthquake Studies (2018)
Ground Motion Prediction Equations (GMPEs) are one of the key elements in seismic hazard assessment to estimate ground motion intensity measures by basically taking into account source, path and site effects. Most of the existing predictive models are derived from databases compiled from real (or observed) ground motion data. However, in data-poor regions, a novel practice to develop new GMPEs is to use simulated or hybrid ground motion datasets for performing reliable seismic hazard analysis. Simulations o...
