Earthquake itself caused about a total of $400,000 of damage. Dense coastal settlements along the south and east coasts of Newfoundland have long been a feature of this part of Canada because of the fish resources provided by the banks. Seismic shaking is a major trigger for sediment redistribution in subduction zones, and clouds of dilute suspended sediment have been reported in association with large earthquakes. Bucher cited effects of the 1929 Grand Banks earthquake and tsunami (speculating, as others had and would, about the cause of the timing of submarine cable breaks); he also mentioned the 1933 Sanriku coast tsunami in Japan.
