Oceanic waves (swell) generate in areas of persistent stormy and high wind speeds (wave factories) and propagate out from there, coalescing one with another during thousand of kilometers, finally reaching the nearshore of coastal waters as almost regularly spaced (here in SW Australia, 12-14 seconds, extremely long) packs of 2-5 similar waves, refracting against he seabed and breaking or surging or spilling on beachfaces.
Swell, is the oceanic expression of an aeolian (wind) process.
The Coriolis Effect, like wind and cyclones paths, has an impact on swell propagation across big distances, but "vibrations" of Earth, on swell do not have impacts.
Earthquakes, vulcanic eruptions and submarine landslides certainly cause anomalous waves (Tsunamis), but do not modify swell.
In conclusion, swell, as far as I know, is not affected by earthquakes.
