Which of the five earthquakes would be the gradient greatest threat to us in Vancouver?

The greatest threat to Vancouver among the five earthquakes would likely be a large magnitude earthquake occurring along the Cascadia Subduction Zone. This fault is capable of producing very powerful earthquakes, potentially exceeding magnitude 9.0, which could cause significant ground shaking, tsunamis, and extensive damage to infrastructure. Given Vancouver's proximity to this fault line, the potential for widespread devastation makes it a serious concern for the region. Additionally, the city's preparedness and response capabilities would be critical in mitigating the impact of such an event.
