| 内容記述 | Analytical expressions of dynamic strains and tilts on the surface of a semi-infinite medium due to a buried shear fault are derived with Cagniard's method. The essential difference compared with the solution in an infinite medium is the appearance of SP and Rayleigh waves in a semi-infinite case. Some examples of strain and tilt waveforms are illustrated and the features of each phase are investigated. For a point source, the amplitude of SP phase is comparable to that of P phase. For this reason, attention must be payed when one analyzes strain records using the solutions in an infinite medium, especially in the case of a shallow focus. For a moving source, if it propagates towards the observing point, the resultant SP phase becomes far larger than P phase by a kind of Doppler effect. Except for the cases mentioned above, the solution calculated in an infinite medium gives generally a good approximation to the exact solution in a semiinfinite medium, at least where the initial parts of waveforms are concerned. | |||||
