Cascadia fault line could be ready to shift. And that would be VERY bad HotAir

Oceanographers working off the coast of Oregon have made a potentially alarming discovery. They ve found a vent in the ocean floor that is pushing out warm water. On the surface, that may not sound all that remarkable or dangerous, but the chemical composition of the water suggests that it s coming up from a deep vent and it s located on top of the Cascadia Subduction Zone. We ve covered this topic here in the past, but if you re not familiar with the CSZ there are some good documentaries online where you can learn the details. The short version of the story is that the CSZ slips on a regular basis every 300 to 400 years. When it does, it causes an earthquake of at least magnitude 8 or 9. And very shortly after that, a tsunami that looks like nothing seen in our lifetimes comes ashore from southern Canada to northern California destroying everything in its path. This leaking vent in the seafloor could be an early indicator that the next slip is on the way.
