Statistical Seismology Science Gateway

Seismic hazard assessment and risk analysis are critical for human life since these fields study and model expected earthquakes to produce seismic hazard maps and to determine the risk of damage from potential earthquakes to buildings, dams, etc. The Statistical Seismology Science Gateway, built on the gUSE framework, holds a comprehensive set of tools and models covering seismic data analysis, hazard assessment and risk analysis. It provides an environment in such a way that skilled users can experiment their own approaches by simply accessing the gateway services, while novice users can easily use existing applications. This chapter focuses on the development of the workflows implementing these tools and models as well as the portlets to access them. It also discusses how easily gUSE framework was customised to build this science gateway and how it is operated.


An Interdisciplinary Approach for Regional Seismic Damage Estimation
Askan Gündoğan, Ayşegül; Erberik, Murat Altuğ; Karim Zadeh Naghshineh, Shaghayegh; Yakut, Ahmet (2017-01-09)
In order to mitigate seismic risk in urban regions, the first task is to identify potential seismic losses in future earthquakes. Seismic loss estimation is an interdisciplinary framework including a wide range of contributions from geophysical and earthquake engineers, physical and economic planners to insurance companies. In this study, a moderate size city in Turkey, namely Erzincan, is modeled completely from geophysical attributes to the built environment. Erzincan city is on the eastern part of the No...
A grid-based seismic hazard analysis application
Kocair, Çelebi; Şener, Cevat; Akkaya, Ayşen; Department of Computer Engineering (2010)
The results of seismic hazard analysis (SHA) play a crucial role in assessing seismic risks and mitigating seismic hazards. SHA calculations generally involve magnitude and distance distribution models, and ground motion prediction models as components. Many alternatives have been proposed for these component models. SHA calculations may be demanding in terms of processing power depending on the models and analysis parameters involved, and especially the size of the site for which the analysis is to be perf...
Prediction of potential seismic damage using classification and regression trees: a case study on earthquake damage databases from Turkey
Yerlikaya-Ozkurt, Fatma; Askan Gündoğan, Ayşegül (Springer Science and Business Media LLC, 2020-09-01)
Seismic damage estimation is an important key ingredient of seismic loss modeling, risk mitigation and disaster management. It is a problem involving inherent uncertainties and complexities. Thus, it is important to employ robust approaches which will handle the problem accurately. In this study, classification and regression tree approach is applied on damage data sets collected from reinforced concrete frame buildings after major previous earthquakes in Turkey. Four damage states ranging from None to Seve...
An assessment of the 3 February 2002 Cay (Turkey) earthquake (Mw=6.6): Modeling of ground motions and felt intensity distribution
Can, Gizem; Askan Gündoğan, Ayşegül (2021-11-01)
Estimation of earthquake ground motions is important for several purposes including seismic design, analysis, risk mitigation and disaster management. For regions with insufficient data, simulations become critical, particularly for earthquake engineering applications requiring full ground motion data. In this study, stochastic finite-fault simulation of the 3 February 2002 Cay event is presented at three available stations within epicentral distances less than 200 km. The simulations are initially validate...
Simulation of large earthquakes and its implications on earthquake insurance rates: a case study in Bursa region (Turkey)
ÜNAL, Baris; Askan Gündoğan, Ayşegül; Kestel, Sevtap Ayşe (2017-01-01)
Ground motion intensity parameters of past and potential earthquakes are required for a range of purposes including earthquake insurance practice. In regions with no or sparse earthquake recordings, most of the available methods generate only peak ground motion parameters. For cases where full ground motion time histories are required, simulations that consider fault rupture processes become necessary. In this study, a major novel use of simulated ground motions is presented in insurance premium calculation...
