In this study, Landsat 5 Thematic Mapper (TM) and SPOT HRV Panchromatic data were analysed to determine the geometry of an active fault segment (the Ganos segment) in Gaziköy-Saros region, west of Marmara Sea, Turkey. Gaziköy-Saros/Ganos segment is a part of North Anatolian Fault Zone (NAFZ). North-Anatolian fault is considered to be one of the most important active strike-slip faults in the wo...

S U M M A R Y We investigate the representation of the radiated energy, E R, in earthquakes. In seismology E R is estimated from either far-field seismic waves or the stress and displacement on the fault plane. Although E R comes from the entire volume of the Earth, it can be expressed as an integral over the fault plane. However, the integrand cannot be given a simple physical meaning such as ...

This paper presents a complete scheme for protection of transmission lines, including fault detection, fault classification as well as fault location. The fault location module utilizes the modeling of transmission lines through their differential equations. The differential equation for the line is solved having its resistence and inductance as parameters. In this approach there is no need for...

to assess seismic hazard, it is essential to estimate the potential seismicity, particularly estimation of size of the largest earthquake that can be identified by a distinct fault or earthquake source. one of the methods applied to estimate magnitude of earthquake is use of empirical relationships between magnitude and fault parameters. fault parameters for the earthquakes from early instrumen...

the near field ground motions have a high amplitude pulse like at the beginning of the seismogram which are significantly influenced by the rupture mechanism and direction of rupture propagation. this type of ground motion cause higher demands for engineering structures and its response spectrum is dramatically different than far field spectra. tabriz is one of the ancient cities in azerbaijan ...

The isolation technique is widely studied and applied in structural engineering due to its excellent seismic performance. However, the existing research mostly focuses on conventional structure under action of regular ground motions. In this paper, a story-adding structure, base-isolated isolated were simulated by using numerical simulation methods. dynamic response characteristics three struct...

additional dampers are employed in order to decrease the dynamic response of structure against the earthquake and wind loading recently. in this study, two types of systems related to waste of inactive energy, i.e. frictional damper which is categorized in dampers dependent on movement and viscoelastic damper which is categorized in dampers dependent on velocity, in making steel structures resi...

Performance coefficients are widely used in seismic design codes to achieve performance objectives. The values of these have significant importance achieving pre-specified goals. Studies shown that near-fault earthquakes decrease the ductility and increase risk failure structures; however, current use same structures against near- far-fault records. In present study, 1-, 5-, 10- 15-story specia...
