Reanalyzation of three focal-mechanism solutions for earthquakes from Jan May en, Iceland and Svalbard

Tectonophysics, 1978
Abstract A reanalyzation of three previously published focal mechanism solutions has given the results presented in Table I. The previous solutions, which are also given in Table I, were published by Bungum and Husebye (1977) for the Jan Mayen event, and by Bungum (1977) for the Iceland and Svalbard events.

Automatic determination of focal mechanism solutions using initial motion polarities of P and S waves

Physics of the Earth and Planetary Interiors, 2004
Abstract This study proposes an automatic method of determining a focal mechanism solution. This method includes picking initial motion polarities of P and S waves and judging reliability of the solution. The method of picking the polarities is as follows. Displacement waveform data are calculated only for S waves.
