How does the moon affect tidal waves?
If by tidal waves you mean a tsunami (caused by earthquakes, landslides, etc), then the answer is no effect However, true tidal effects are caused by the slight difference in the moon’s gravitational pull on different parts of the earth. This differential pull has the effect of creating two tidal bulges on the ocean surface, one on the side of the earth facing the moon and one on the opposite side of the globe. These two bulges correspond to high tides. So as the earth rotates, every place (other than polar regions) will experience two high tides and two low tides per day.
