Magnitude information is an essential measure when assessing risks of large-scale earthquakes and tsunamis. Tsunami deposit characteristics, inundation characteristics, tsunami hydrodynamics, and sedimentation processes are the keys to obtaining magnitude information. Research on the 2011 off the Pacific coast of Tohoku Earthquake and Tsunami covering both terrestrial and subaqueous environments offers a basis for drawing a comprehensive picture of tsunami sedimentology, and increasing our ability to extract magnitude information. Issues related to estimating magnitude information related to a tsunami from its deposits are discussed in the context of some recent and earlier research on the 2011 and 869 Jogan earthquakes and tsunamis, and implications for future research are presented.
