Revisiting
the Seismolab seminar by Yoshiyuki Kaneda (Japan Marine Science & Technology Center - JAMSTEC): "Outline of Plate Dynamics Research Program in IFREE/JAMSTEC" The speaker presented a lot of data and (seismic, & rheological) modeling results using a large number of slides at the Seismolab seminar . The point of this discussion is to go over these slides more carefully to gain a better understanding of the current state of knowledge of the Japanese subduction zone (primarily, Japan trench & Nankai trough). |
