The ability of Japanese strong-motion arrays for inferring earthquake source processes is investigated using a source inversion method previously developed on the basis of the Wolberg's prediction analysis. The ability of the whole array and the contribution of individual array stations are estimated for three array networks existing in Japan. They are for the 1984 Naganoken-seibu earthquake, the 1978 Miyagiken-oki earthquake, and the anticipated Tokai earthquake.
The results indicate that two different kinds of stations are simultaneously required to infer detailed source processes. One is near-source stations, and the other is stations surrounding the earthquake fault with good azimuthal coverage.
