Japan is located on the Pacific Ring of Fire, a region of special interest in earthquake research. The range of possible earthquake magnitudes and specifically the processes driving giant earthquakes – i.e. earthquakes with a moment magnitude (Mw) of nine or more – and how often they occur, however, is not fully understood. To gain an improved perspective of earthquake maximum magnitude and recurrence, researchers need to look back into the geological record. This is the aim of the upcoming International Ocean Discovery Program (IODP) Expedition 386 “Japan Trench Paleoseismology”, involving a team of scientists who will leave the port of Yokusuka onboard the research vessel Kaimei on 13th April 2021.

The expedition is led by Dr. Ken Ikehara, from the Geological Survey (AIST) in Japan, and Prof. Michael Strasser at the Institute of Geology, University of Innsbruck (Austria). Michael Strasser is an associate member at MARUM and works closely with researchers in Bremen.
