Buildings in Lord's Cove tossed and smashed by the tsunami. [8] Scientists have examined other layers of sand believed to be deposited by other tsunamis in an effort to determine the occurrence rates of large earthquakes. 1, p. 97-148. [6], In 1952, American scientists from Columbia University put together the pieces of the sequentially broken cables that led to the discovery of the landslide and the first documentation of a turbidity current. At the heads of several of the long narrow bays on the Burin Peninsula the momentum of the tsunami carried water as high as 13 metres. The worst damage was reported on the island then named Île-aux-Chiens (meaning Island of the Dogs; till 1931), now known as L'Île-aux-Marins (The Island of the Sailors).

[citation needed] One sand layer, thought to be deposited by the 1929 tsunami, at Taylor's Bay was found 13 centimetres (5.1 in) below the turf line. Seismologists at Canada's Dominion Observatory determined the original intensity values by sending questionnaires to local postmasters (here's a sample intensity questionnaire response from Lewisporte, Newfoundland). The Negative Impact on the Natural Systems The tsunami affected the tides and ocean currents. The day following the tsunami a winter storm moved into the area, dropping temperatures and adding sleet and snow to the survivors' misery.

This destruction of the seabed was believed by many Newfoundland fishers to be the dominant factor in poor fish catches during much of the Great Depression. The earthquake triggered a large submarine slump (an estimated volume of 200 cubic kilometres of material was moved on the Laurentian slope) which ruptured 12 transatlantic cables in multiple places (locations of cable breaks can be seen as small red triangles on the isoseismal map) and generated a tsunami (a large induced sea wave).

The word tsunami usually brings to mind seismic waves in the Pacific or the Indian Oceans. This region, called the Laurentian Slope Seismic Zone, aligns north-south along the southern edge of the Grand Banks near Newfoundland. While there are few studies of prehistoric tsunami deposits in low-latitude regions, surveys of recent tsunami effects, in addition to 2004, include Indonesia, Philippines, Papua New Guinea, Hawaii, Peru, Nicaragua, the Caribbean and Mediterranean.

The deposition of such a large volume of sediments will take a while before there is enough to form an underwater landslide the same size as that in 1929. The poor catches seem to be the result of a failure of the bait fishery. The quake’s epicentre was located about 400 kilometres south of the Grand Banks of Newfoundland. Data took weeks to collect and months to interpret. Analyses of the 1929 Grand Banks tsunami indicate that it was generated by the large slope failure rather than by the earthquake itself (Murty, 1977, Clague, 2001). 36 The 1929 Grand Banks tsunami plays an especially important role in this regard.
