Fig. 4From: Prediction of maximum P- and S-wave amplitude distributions incorporating frequency- and distance-dependent characteristics of the observed apparent radiation patternsSpatial distributions of modeled radiation pattern coefficients. Frequency ranges are a 0.5–1 and b 4–8 Hz, respectively. Theoretical radiation pattern coefficients in infinite homogeneous medium are also plotted in c. d Assumed one-dimensional velocity structure model (Ukawa et al. 1984) and calculated takeoff angles of Event 11 (depth of 11 km)Back to article page
