Relationship between the accuracy of a source inversion and fault-arry parameters and optimum array geometry for the source inversion are quantitatively investigated. The estimation is done by using a source inversion method based on the Wolberg's prediction analysis. A complete Green's function in an elastic half-space is taken into account in the source inversion. The results obtained suggest that numerous stations surrounding a fault are required to investigate the detailed fault rupturing process and are consistent with the array geometries proposed at the 1978 International Workshop on Strong-motion Earthquake Instrument Arrays. The optimum strong-motion array for a strike-slip fault is characterized by stations well distributed in azimuth, while the optimum array for a dip-slip event has stations arranged in a grid-shaped form. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
