With the aid of equations (72) and (76) we can determine the horizontal displacement q(t), using its operational representation given in equation (65). 4. Summary.-An exact solution is given for the motion of the surface of a uniform elastic half-space produced by a point pressure pulse situated at a depth H below the surface. The time variation of the pressure pulse is assumed to be given by t...

SUMMARY The ongoing InSight mission has recently deployed very broad band seismometers to record the Martian seismic activity. These recordings constitute first data set collected at surface of Mars. This unique but sparse compels for development new techniques tailored make best use specific context single station-multiple events with several possible ranges uncertainties on event location. To...

The accurate location of seismic events is a basic discriminant for underground nuclear test monitoring (Bolt, 1976; Dahlman and Israelson, 1977; Blandford, 1982). Of particular interest are determining epicentral confidence regions and providing constraints on estimated focal depths. In this study, only routine teleseismic P travel-time data are used, as provided by worldwide stations reportin...

The spectral decay parameter, K, defined by Anderson and Hough (1984) is described as a function of distance, R, and site, S, as K(R, S) = Ko(S ) + E(R). The terms E(R) and K0(S) are found by a method that is unbiased by prior assumptions about the nature of the distance dependence. Variance using this model is substantially smaller than in simpler models that do not incorporate both site effec...

In the present work, a multiscale post-seismic relaxation mechanism, based on existence of distribution in time, is presented. Assuming an Arrhenius dependence time with uniform distributed activation energy mesoscopic scale, generic logarithmic-type macroscopic scale results. The model was applied case strong 2015 Lefkas Mw6.5 (W. Greece) earthquake, where continuous GNSS (cGNSS) series were r...
