The new year 2005 National Building Codeaccounts for the expected level of earthquake shaking from a similar earthquake anywhere along the length of this margin. The quake’s epicentre was located about 400 kilometres south of the Grand Banks of Newfoundland. There was never an accurate official list of the victims produced by any branch of the Newfoundland government. Also lost were more than 280,000 pounds of salt cod.

On November 18th, 1929, at 5:02pm local time, a magnitude 7.2 earthquake ruptured approximately 250 kilometers offshore of Newfoundland. The shock had a moment magnitude of 7.2 and a maximum Rossi–Forel intensity of VI (Strong tremor) and was centered in the Atlantic Ocean off the south coast of Newfoundland in the Laurentian Slope Seismic Zone. On November 18, 1929, a M = 7.2 earthquake occurred at the southern edge of the Grand Banks (at the mouth of the Laurentian Channel), 250 km south of Newfoundland. Damage on land was concentrated on Cape Breton Island in the northern part of Nova Scotia where chimneys were overthrown or cracked. 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.

November 1929 — One of many houses the tsunami destroyed on the Burin Peninsula. Although the Grand Banks earthquake occurred only 75 years ago, the general feeling in the scientific community is that similar tsunami-generating earthquakes are very rare. Simplified schematic plot of the velocity profile (a) before and (b) during the slump motion simulated with the depth-averaged BingClaw model (modified after Kim et al. The star indicates the epicenter of the earthquake. 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).
