What's in a Name?
How Mount Breakenridge Got Its Name
The mountain was named by Lieutenant Palmer in 1859. He named it after Archibald T. Breakenridge, who was part of his team. They were exploring the area from Harrison Lake to the Lillooet River.
The Local Name for the Mountain
The local Indigenous people, called the Lower Lillooet people, have their own name for the mountain. In their language, Ucwalmícwts, the mountain is called mólkwcen. This name is also used for a fishing spot near Stokke Creek, which flows into Harrison Lake from the mountain.
Understanding Landslides and Tsunamis
What is a Landslide?
Mount Breakenridge is being studied by scientists because of a large crack on its side. This crack is called a shear zone. It's like a big fracture in the rock. Scientists worry that a large part of the mountain could break off and fall into Harrison Lake.
How a Landslide Can Cause a Tsunami
If a big piece of the mountain falls into the lake, it would push a huge amount of water. This could create a very large wave called a megatsunami. These waves can cause a lot of damage. The cracks in the mountain might have become bigger because of heavy rain and small earthquakes in the area.
What is a Tsunami?
When a landslide happens in water, it can create a tsunami. This is when the falling rock or debris pushes the water, making big waves. These waves can be very powerful. They can cause a lot of damage, especially in narrow parts of the coast where the wave's energy gets stronger.
What Could Happen?
Areas and Industries at Risk
If a landslide and tsunami happened at Mount Breakenridge, it could cause a lot of destruction. These types of waves are strong enough to harm nearby towns. They can even wash away all the sand from a beach.
The town most at risk is Harrison Hot Springs, located at the south end of the lake. Other towns that could be affected include Port Douglas at the north end of the lake, and even parts of the Fraser Valley. Any town along the Harrison River could also be in danger.
Many local businesses would also be affected. Roads could be destroyed, making it hard for logging trucks to move wood. Fishing businesses might not be able to work because the lake would be disturbed. Tourist activities like skiing and camping would also be badly affected.
Safety Plans in Place
People in the areas that could be affected have some safety plans. There are special walls and structures built to help stop debris from flowing onto roads. There is also a tsunami warning system. This system uses sirens, phone calls, and door-to-door messages to tell people about danger.
You can also find safety information online. These resources suggest plans like getting to higher ground quickly if a tsunami warning is given. However, there might not be much time to react if a tsunami happens suddenly.
How the Area Can Recover
More buildings and homes are being built in the region. This means the community could be more vulnerable to a disaster. However, the natural forests in the area might help reduce the force of a tsunami. This could lessen the damage and save lives.
After a big event like a tsunami, nature usually starts to heal itself. This is called secondary succession. It means that if the area isn't completely destroyed, plants and animals can eventually return. But how well the area recovers also depends on how people help clean up and rebuild. Roads, factories, and homes might need to be rebuilt, either partly or completely.
Why This Matters
It's important for everyone to know about the possible danger from Mount Breakenridge. Tsunamis are very powerful, but people can prepare to lessen the damage. This includes planning how to evacuate and being ready to help with recovery efforts.
People's homes, jobs, and lives are at risk. The animals and plants in the area are also in danger. If rare species are lost, it could greatly affect the local ecosystem. The economy would also suffer a lot, especially the logging, fishing, and tourism industries.
Past Tsunamis in British Columbia
British Columbia has experienced tsunamis before.
- In 1700 and 1946, tsunamis caused by earthquakes happened but did not reach the shore.
- In 1960, a huge earthquake caused a tsunami that damaged log booms in Tofino.
- In 1964, another large earthquake caused a 14-foot wave. This wave flooded parts of Hot Springs Cove, Bamfield, and Port Alberni. It traveled very fast and caused about 8 million dollars in damage.
- The last tsunami, in 1975, was caused by an undersea landslide in the Kitimat Inlet.
