Mass Wasting in Canada

 Ross Frank

10/7/2025

Landslides are a serious natural disaster that often happens in different parts of Canada, especially in places with mountains or steep hills. They occur when rock, soil, or mud slides down a slope, usually because of heavy rain, melting snow, earthquakes, or even construction that weakens the ground. British Columbia experiences the most landslides because it gets a lot of rain and has rugged terrain. These events can damage roads, homes, and power lines, and sometimes they even take lives. The cost of repairing the damage can be very high, and landslides continue to be a big problem for many Canadian communities.


In Canada, landslides cost an estimated $200-$400 million a year. The flow rates of landslides can get upwards of 100 km/hr (62 MPH). This isn't shocking because, according to the Government of Canada, thousands of landslides occur every year across the country. The deadliest landslide in Canadian history happened in 1903. A small mining town known as Frank, Alberta, was caught underneath 82 tons of limestone rock that slid down Turtle Mountain. 73 people, unfortunately, lost their lives in this tragic accident. Between the years of 1771 and 2019, there have been a total of 786 landslides that have resulted in deaths in Canada. Of those 786, 356 have been in British Columbia.

    Hello Ross, thank you for posting this! I enjoyed reading your post and learning more about mass wasting in your country.

      I imagined Canada would have many interesting natural phenomena because I thought about snowslides and how the ground in its mountains would always be wet. I also thought there would be many streams from the melting snow. In addition, avalanches can occur during certain times of the year.
      Something that surprised me was the amount of money landslides cost Canada each year. I was also shocked by how they affect the population, especially when they knock out power or block roads that are likely very important for transportation.

    You did a great job explaining how landslides impact Canada and supported your points with strong facts and statistics. Your paragraph clearly shows how serious and widespread this issue is, especially in British Columbia. - Switzerland BY

    Very interesting- what would be the suggested mitigation efforts for this hazard?

The Position of Tectonic Plates in Canada

Image
 Ross Frank Earth Catastrophes and Disasters August 27, 2025      Canada is located in the northern part of North America. So, it is covered almost completely by the North American plate. The only part that isn't inside the North American Plate, is the western most part of Canada. The plate that is touching the North American Plate there is the Juan De Fuca Plate. Even though there are no plate boundaries, there is still a lot of seismic activity all around Canada. Most of the seismic activity happens in the eastern half of the country. There isn't a real explanation for the activity since there is no plate boundary, but it is believed to be due to crustal weakness in these areas.  Image:  https://geology.com/plate-tectonics.shtml#lithospheric Info:  https://www.seismescanada.rncan.gc.ca/zones/eastcan-en.php

Coastal Erosion in Canada

 Ross Frank Earth Catastrophes and Disasters 11/15/25       Coastal erosion occurs when land and sediment are eroded from coasts due to waves, rain, human activities, and other factors. This can lead to land and property getting swallowed up by the rising sea levels, which changes the waves in coastal regions. Canada has the longest coastline in the world, at 243,797 km. So, coastal erosion would be a natural hazard that would affect millions of Canadians. Coastal erosion can be caused by waves due to the rising sea level. All over Canada, shorelines are being forced inland because of the rising sea. This is a problem because that means there is a loss of land and property. There are also habitats that get lost with the loss of land on the coasts. Due to the size of Canada's coastline alone, I would say that there is a great risk of coastal erosion affecting the country. Erosion is a natural process, so there is no way to stop it from happening. But there are ways to...

About My Country - Canada

 Ross Frank August 21, 2025 Earth Catastrophes and Disasters The country that I chose for this semester is Canada. Canada was founded on July 1, 1867. It is located in the northern part of North America. It has a population of 38.8 million as of 2024. Most of Canada is a cold and snowy place, so in the wintertime there are a lot of avalanches. With all that snow in the spring there are a lot of floods once the snow begins to melt and come down the mountains. Another hazard that occurs a lot is earthquakes.        It is good to know the difference between hazards, disasters, and catastrophes. First, everything falls under the umbrella of natural processes. Once humans get in its path, that's when it becomes a hazard, or it has the potential of threating human life. One step up from that is a disaster. A hazard is considered a disaster when it happens within a certain amount of time withing a defined space. The next level up from there is a catastrophe, it is...
