They are in a big tsunami warning and watch in the immediate area west of the quake.

That is pretty much standard procedure until the quake can be evaluated. Because tsunami’s are generated by surface movement, a quake focused 16 miles below the surface creates very LITTLE surface movement. The area west of the center MAY see a tiny wave, but it will not cause problems.
People are jumpy - with good cause.
