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.
What is the moment tensor in this context?
The moment tensor is the graph on my link which describes the forces that cause an earthquake and is used to analyze the fault movement that generates seismic waves
