IODP drilling off Tohoku: J-FAST science to be expanded by Expedition 386
Having knowledge that resulted from IODP Expedition 343 JFAST in hand, looking at paleoseismic events, “fossils” of past earthquakes, becomes more important. The slope from the continental shelf to the Japan trench is not a gentle slope; it is rough, with terraces and basins, which seismic reflection surveys tell us have been filled with layers of deposits from other slope failure events.
