In the 1950s, my father helped build the dams and tunnels at Kemano to help provide power for the Kitimat aluminum smelters.

I experienced my first magnitude 7.0-7.5 earthquake when I was almost 23 months old. It almost knocked me to the ground. That 1946 Vancouver Island earthquake struck Vancouver Island on June 23 at 10:15 a.m.[1] with a magnitude estimated at 7.0 Ms[2] and 7.5 Mw.[6] The main shock epicenter occurred in the Forbidden Plateau area northwest of Courtenay. While most of the large earthquakes in the Vancouver area occur at tectonic plate boundaries, the 1946 Vancouver Island earthquake was a crustal event. Shaking was felt from Portland, Oregon, to Prince Rupert, British Columbia. This is one of the most damaging earthquakes in the history of British Columbia, but damage was restricted because there were no heavily populated areas near the epicentre, where severe shaking occurred. There were, however, a whole series of landslides in the Forbidden Plateau area there were a whole series of landslides blocked streams and rivers to create lakes. The first hikers into the area gave them great names, Landslide Lake, Rock Fall Lake, Earthquake Lake etc.; over time these natural dams were eroded to nothing, leaving nothing but fading memories of those lakes. This earthquake is Canada's largest historic onshore earthquake.[1] Three years later, an earthquake, an M8.1, struck at 8:01 p.m. PDT on August 2, 1949 in Haida Gwaii [formerly Queen Charlotte Islands], an interplate earthquake that occurred on the ocean bottom just off the west coast of the main south island [Graham Island]. The shock had a surface wave magnitude of 8.1 and a maximum Mercalli Intensity of VIII (Severe).

Even though tankers carry thousands of tons of flammable fuel around the world, you don't hear of them exploding. Have you ever asked yourself why? If a car catches fire, it often results in a fireball. Why doesn't the same happen with ships? ----------------------WITH THANKS----------------------- ★ IMAGES Image of tanker: MaxWebb (Shutterstock) World map image: Ekler (Shutterstock) ★ Music & Sound Effects Music & Sounds Effects by Epidemic Sound (http://www.epidemicsound.com) -------------------------DISCLAIMER-------------------------- All content on this channel is provided for entertainment purposes only.
