Looks like it was a strike-slip fault, so a much lower tsunami risk compared to a subduction / dip-slip fault.

Beachball (moment tensor) says it's a thrust fault with a ton of lateral movement (aka attempted subduction.) https://earthquake.usgs.gov/earthquakes/eventpage/us6000tkt2... eyeballs filled in are pretty much thrust faults and horizontal like that means subduction-possible movement.
