Earthquake Occurrence and Effects in Ocean Areas 
Wilson, B. W., Technical Report CR 69.027 
Publication Date: February 1969 
Location: Worldwide 
Period of Coverage: Varies from site to site; however, this document 
deals mainly with the 1900s. 
Contents: This document evaluates earthquake hazards in ocean areas through- 
out the world. It seeks to examine some of the available earthquakes and 
their associated ground movements, and hence to appraise the potential effects 
of such motions on ocean bottom structures, both from the standpoint of the 
ground-motion itself as well as the hydrodynamic effects of the surrounding 
water. 
Data include a map of the distribution of seismic zones in the world, 
cross-sectional maps of high-risk earthquake zones showing earthquake epi- 
centers and hypocenters, maps of oceanic plates, seafloor spreading, and 
oceanic trenches and ridges. Other data and information are given (see table 
of contents). 
This report presents collectively a large number of undersea earthquake 
information and data for engineers; however, none of the data presented here 
are original.
