Receiver function analysis is one of the most powerful methods for modeling the subsurface structure beneath a seismograph station. Based on the assumption that similar receiver functions should be observed at stations located close to each other, we can construct a spatial distribution of a seismic velocity interface, such as the Moho discontinuity, to trace the distribution of P-to-S (Ps) con...

Abstract Records of 58 identical broadband seismograph stations were studied made during strong geomagnetic storms. Oscillations periods a few hours studied. These compared with synchronous variations earth tides. Anomalous changes in deformation rate observed after storms at installed near continent–ocean boundaries. They lasted days and had amplitudes millimeters per minute.
