Most people don't understand the difference between regular waves (surface waves) and tsunami waves (seismic sea waves). Surface waves are caused by wind the uneven floor of the continental shelf that extends a short way into the ocean. Only the surface waters (about 10 meters deep) are affected. Tsunami waves are the entire ocean surging, much more water involved.
I hope the surfers in Cali understand this difference.
