Quebec rockslide

The Quebec rockslide occurred on September 19, 1889, after a day of heavy rain in Quebec City, Canada. An overhanging piece of slate rock broke off from Cap Diamant and fell 90 metres (300 feet) onto the houses below. The homes of 28 families on Champlain Street were crushed, burying roughly 100 people under 24 metres (80 feet) of broken slate rock. The final death toll exceeded 40 people.[1]

Cap Diamant

Cap Diamant (English: Cape Diamond) is a cape on an edge of the Promontory of Quebec and on which Quebec City is located, formed by the confluence of a bend in the St. Lawrence River to the south and east, and the much smaller Saint-Charles River to the north.

Jacques Cartier, the French explorer who found glittering stones in the high cliff, thought the stones contained diamonds. After he brought samples of these stones to France in 1542, experts concluded that these "diamonds" were actually quartz, hence the proverb "Faux comme un diamant du Canada" ("as fake (or as false) as a Canadian diamond").In 1759, the troops of British General James Wolfe climbed Cap Diamant toward the Plains of Abraham to conquer Quebec.

In 1889 the Quebec rockslide fell from Cap Diamant.


The term landslide or less frequently, landslip, refers to several forms of mass wasting that include a wide range of ground movements, such as rockfalls, deep-seated slope failures, mudflows, and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides. Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event (such as a heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable.

List of disasters in Canada by death toll

List of Canadian disasters by death toll is a list of major disasters (excluding acts of war) which occurred in Canada or involved Canadian citizens, in a definable incident, where the loss of life was 10 or more.

List of landslides

This list of landslides is a list of notable landslides and mudflows divided into sections by date and type. This list is very incomplete as there is no central catalogue for landslides, although some for individual countries/areas do exist. Volumes of landslides are recorded in the scientific literature using cubic kilometres (km3) for the largest and millions of cubic metres (normally given the non-standard shortening of MCM) for most events.
