Subduction zone guided waves and the heterogeneity structure of the subducted plate: Intensity anomalies in northern Japan
The subducting Pacific plate acts an efficient waveguide for high-frequency signals and often produces anomalously large intensity on the eastern seaboard of northern Japan during deep earthquakes. The waveform records in the region of high intensity show a low-frequency (f < 0.25 Hz) onset for both P and S waves, followed by large, high-frequency (f > 2 Hz) later arrivals with a long coda. This behavior is not explained by a simple subduction zone model comprising a high-velocity plate with...[Show more]
