1929: Grand Banks
built 194 days ago
On November 18, 1929, at 017:02 Newfoundland time, an earthquake occurred of the coast of Grand Banks, Newfoundland. A tsunami was triggered by a sub-marine landslide and the earthquake, which had a Richter magnitude of 7.2 with an epicenter of 44.5°N, 56.3°W. The tsunami caused $400,000 in damage and killed 29 people, the highest death toll attributed to an earthquake in Canada.

The 1929 Laurentian slope earthquake, along with the 1933 Baffin Bay magnitude 7.3 event indicate that large earthquakes along Canada's eastern continental margin are not uncommon. The new year 2005 National Building Code accounts for the expected level of earthquake shaking from a similar earthquake anywhere along the length of this margin. 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.

When originally commissioned in 1929, the intent for the mural was that it would remain on Market Street. As WSFS Bank commemorates its 175th Anniversary, it is meeting the expectations of the community that the mural will stay on Market Street and will be preserved for current and future generations of Delawareans.

On November 18, 1929 at 5:02 pm Newfoundland time, a major earthquake occurred approximately 250 km south of Newfoundland along the southern edge of the Grand Banks. This magnitude 7.2 tremor was felt as far away as New York and Montreal (see isoseismal map of felt area below). On land, damage due to earthquake vibrations was limited to Cape Breton Island where chimneys were overthrown or cracked and where some highways were blocked by minor landslides. A few aftershocks (one as large as magnitude 6) were felt in Nova Scotia and Newfoundland but caused no damage.
