The interpretation of diatom biostratigraphy is a little used technique in the study of onshore
tsunami sedimentation. Evidence is presented from examples from three tsunamis in which
sediments were either observed to have been deposited; documentary evidence attests to
the presence of sediment sheets, or finally, in the case of palaeo tsunamis, morphological
and stratigraphical evidence permits the interpretation of tsunami inundation and the
subsequent deposition of sediment. Examples from Scotland and Canada, and preliminary …

Evidence is presented from examples from three tsunamis in which sediments were either
observed to have been deposited; documentary evidence attests to the presence of
sediment sheets, or finally, in the case of palaeo tsunamis, morphological and stratigraphical
evidence permits the interpretation of tsunami inundation and the subsequent deposition of
sediment. Examples from Scotland and Canada, and preliminary results from Indonesia,
illustrate distinctive diatom assemblages that are associated with tsunami sedimentation.
