Abstract

The aim of this paper is to characterize tsunami deposits in Holocene peat at tidal marshes on northwestern Vancouver Island. The AA. studied the architecture, stratigraphy, and sedimentology of 2 sand sheets at Fair Harbour, Neroutsos Inlet, and Koprino Harbour to understand their deposition, preservation, identifying characteristics, and paleoseismic significance. The 2 sand sheets are similar in age, stratigraphic position, and morphology to tsunami deposits farther south that have been attributed to the 1964 Alaska earthquake and to the last great earthquake on the Cascadia subduction zone about 300 yr ago
