Moment tensor solution of the June 4, 2000 southern Sumatra, Indonesia, Ms8. 0 earthquake is estimated from teleseismic body waves recorded by long period seismograph stations of the global seismic network.
The moment tensor solutions of the March 25,1998,Antarctic plate earthquake (Mw=8.1,IRIS) and the June 4,2000,southern Sumatra,Indonesia,earthquake (Ms=8.0) were inverted using teleseismic body waves recorded by long period seismograph stations of the IRIS global seismic network.
Using teleseismic body waves recorded by long period seismograph stations of the global seismic network, the temporal-spatial source process of the June, 4,2000 southern Sumatra M S8.0 earthquake, Indonesia, was studied.
3. For the random seismic response analysis of layered sites, by combining the randomvibration and wave theory, the status of inclined body waves and the influence of elastic rock can beanalyzed conveniently.
The first,the generalized dispersion equations for the bulk wave with bonding conditions are derived. The second,the relation of the measurement accuracy with the bulk wave dispersion of the piezobiosensors are discussed and simulated by computer. At last,the theory is proved correct by the experiment results.
Based on the high-resolution body wave tomographic image and relevant geophysical data, we calculated the form and the vertical and tangential velocities of mantle flow.
Body wave velocity distribution in the Benioff zone of central Kamchatka during aftershocks of the Kronotskii earthquake of 1997
We consider a method for deriving relativistic two-body wave equations for fermions in the coordinate representation.
Variation in the duration of crawling bouts, the tendency to body wave, the rate of standing, the duration of standing bouts, and the tendency to jump after standing contributed to the differences in frequency of jumping among species.
S-wave velocity structure beneath the Ailaoshan-Red River fault was obtained from receiver functions by using teleseismic body wave records of broadband digital seismic stations.
Propagation of nonlinear body waves in a magnetic tube
The propagation of slow symmetrical small-amplitude body waves in a cylindrical magnetic tube is investigated on the basis of the nonlinear equation obtained in [3, 4].
Furthermore, two numerical examples of two-dimensional problems demonstrate the existence of two body waves, i.e.
Applying the analytical solution of plane waves, we give the velocity and attenuation coefficient of three body waves, which are affected by the wave frequency and the weakness factor of saturated discrete media.
Our results show that velocity decreases with increasing weakness factor, the attenuation coefficient increases with an increase in the weakness factor, and that the influence of weakness depends on the mode of the body waves.
On this basis, the possibility of a resonance interaction between a surface elastic SH wave propagating in the magnetic superlattice and a shear bulk wave propagating in the adjacent nonmagnetic medium is investigated.
The ratio of the moduli of the tangential components of these amplitudes is analyzed as a function of the angle of incidence and the polarization of the bulk wave.
It is shown that a polariton in the plane of propagation (sagittal plane) passing through the optical axis is transformed into a one-partial bulk wave satisfying the boundary conditions.
The frequency ranges in which the extraordinary polarized waves under analysis can exist are found, and the conditions for their resonant interaction with an ordinary bulk wave are determined.
Degeneration of a SAW into a transverse bulk wave is another strong effect influencing the anisotropy of the SAW amplitude and making whole sections of the SAW wavefront including some phonon focusing directions unobservable in the experiment.
