It is stretching roughly 600 miles from Northern California to Vancouver Island, and this brings attention to the massive tectonic stress beneath the North American plate.

According to research, it has been estimated that there is a 15% chance of a magnitude eight point oh and even greater earthquake that can occur within the next 50 years. According to the study, this event is a catastrophic event and can create a work and suddenly sink coastal land by up to 6.5 feet' and it can also generate tsunami waves that are hundreds of feet high, posing a lot of risk to the millions of residents, critical infrastructure, and ecosystems along the west coast.
