Answer:
Explanation:
Landslides and avalanches have resulted in more than 600 deaths in Canada since 1840 and have caused billions of dollars in damage. These mass movements of soil, rock or snow occur in all parts of the country, in mountains and flatlands, and usually without warning. Hazards include the impact of rapidly moving debris, the collapse of ground beneath a structure and secondary effects such as river damming and landslide-generated waves.
Landslides and avalanches are defined according to the size or type of debris generated, distance moved, speed of flow and underlying geology. There are eight major types that occur in Canada -- rock avalanches, debris avalanches, snow avalanches, flowslides, rockslides, rock falls, debris flows and slumps. Surprising to most, they don't only occur on a steep mountain slope. Many parts of Canada face some form of avalanche or landslide hazard.
A rock avalanche is the disintegration of a large rock mass on a mountain slope and its rapid movement downhill. The 1959 Pandemonium Creek avalanche in BC reached speeds of up to 360 km/h. In 1903, 90 million tonnes of limestone fell from Turtle Mountain and buried the coalmining town of Frank, Alberta where about 75 people died.
Prevalent only in BC, debris avalanches involve the rapid mass movements of rock originating on the slopes of volcanoes. Several have taken place in this century on the Pleistocene volcanoes of the Garibaldi Volcanic Belt in southwestern BC. They are a major hazard to development in the region.
