From: Lg wave propagation in the area around Japan: observations and simulations
Record section and snapshot derived by FDM simulation along profiles A and B. Record section of vertical-component seismogram along (a) profile A (to Kyushu) and (b) profile B (to Honshu across the Sea of Japan) and the snapshots of P (red) and S (green) wavefields at 80, 200, 320, and 440 s from earthquake start. Theoretical travel time curves for the major phases are shown.
