| Abstract: | Summary The estimation of the theoretical short-period PKiKP/PKIKP magnitude calibrating curves for deep foci, based on the Earth model PREM and the zero approximation of the ray theory is presented. A set of calibration curves is given for periods 0.8 s, 1.2 s and 1.6 s, for depths 25 km, 200 km, 400 km and 600 km and the epicentral distance range of 12 200 km to 19 800 km. In the calculation we consider the mutual interference of PKiKP and PKIKP wave branches in the corresponding distance range of 13 000 km to 16 000 km for the chosen Gabor's signal. Calibrating curves reflect mainly the distribution of model parameters, the prevailing period and in the distance range of interference also the form of the chosen signal. |
