A probability model for regional focal mechanism solutions
Bulletin of the Seismological Society of America, 1980abstractThe increase in the number of determinations of fault-plane solutions and their use for inferences on regional and local tectonics and stress fields makes it advisable to treat them in a standard way in groups on a regional basis. Probability models for joint group estimation of the shear dislocations, involving data from I earthquakes and J ...

Focal mechanism and source depth of earthquakes from body- and surface-wave data
Bulletin of The Seismological Society of America (BSSA), 1971The determination of focal depth and other source parameters by the use of first-motion data and surface-wave spectra is investigated. It is shown that the spectral ratio of Love to Rayleigh waves (L/R) is sensitive to all source parameters.

Two focal-mechanism solutions for earthquakes from Iceland and Svalbard
Tectonophysics, 1977Abstract Strike-slip solutions have been obtained and are presented here for the focal mechanisms of one earthquake from Iceland and one from Svalbard, on 13 and 18 January 1976, respectively. A fault plane is suggested for the Iceland earthquake.

Focal mechanism solutions for Albanian earthquakes for the years 1964–1988
Tectonophysics, 1994Abstract Focal mechanism solutions for 175 Albanian earthquakes of Albania for the years 1964–1988 were obtained by using an interactive computer technique. The results obtained are elaborated upon by applying Fisherian statistical analysis to obtain parameters for the mean stress direction in five zones.

Focal mechanism solutions and its tectonic significance in the trench of the eastern South China Sea
Acta Seismologica Sinica, 2005According to the activity of earthquakes and volcanoes along the Manila trench and its adjacent region, combined with analysis of focal mechanism solutions and geophysics data, the Manila trench is still being downward subduction in the depth of 200 km.

Modern tectonic stress field in the Chinese mainland inverted from focal mechanism solutions
Acta Seismologica Sinica, 1999The inversion of modern tectonic stress field in China is made by regions on the basis of focal mechanism data in the period of 1920–1996. Results of the inversion show that the maximum principal compressive stress σ1 axis strikes nearly north-south direction in the Tibet Plateau and western China, east-west direction in North China.
