Model and observed seismicity represented in a two dimensional space
Annals of Geophysics, 1976 In recent years theoretical seismology lias introduced<br />some formulae relating the magnitude and the seismic moment of earthquakes<br />to the size of the fault and the stress drop which generated the<br />earthquake.<br />In ...

Evaluation of Performance Levels and Response Modification Factors for Prestressed Reinforced Concrete Frames Using Nonlinear Pushover Analysis [PDF]
Journal of Structural and Construction Engineering, 2018 The use of different methods of prestressing systems is very common in gravity frames at the present time. This technology can also be used in lateral load resisting frames.

Seismic moment tensors and kinematic source parameters [PDF]
Geophysical Journal International, 1982 Summary. Parameters pertaining to the kinematics of a finite source are usually estimated by fitting specific fault models to the data. On the other hand, these parameters, including source location, are also contained in the moment tensors of higher degree.

Seismic attenuation in Faroe Islands basalts [PDF]
We analysed vertical seismic profiling (VSP) data from two boreholes at Glyvursnes and Vestmanna on the island of Streymoy, Faroe Islands, to determine the magnitude and causes of seismic attenuation in sequences of basalt flows.

Optimal estimation of scalar seismic moment [PDF]
Geophysical Journal of the Royal Astronomical Society, 1982 Summary. For any seismic source specified by a frequency-dependent moment-rate tensor M(ω), we define the total moment MT(ω) =||M||/2 and the isotropic moment MI(ω) =|trM|/6. A method is presented for estimating these scalar seismic moments from noisy seismic data when the source mechanism is uncertain or completely unknown.
