1. There might be, just with those accounts not having been encountered due to the relative sizes of the groups involved. 2. Take a look at the map of where the epicenter is estimated to be and it’s fairly clear how the kink point in the California coastline where it switches from running N-S to NW-SE would “catch” (probably not the correct term) the tsunami with land and prevent it from going further. 3. An examination of the topography of the areas near the Pacific coast in what’s now SW Oregon and NW California shows why few Native groups would have chosen to live there in 1700 and why a tsunami would be less likely to leave an impact big enough to be remembered: it’s mountainous and inhospitable, with the elevation rising rapidly and the population low to this day. A unexpected middle of the night quake (estimated to have been around 9pm local plus the hours for the water to travel) washing away a couple fishing boats while everyone in a tiny tribe was asleep would be a small misfortune, not enough to make up legends about fighting gods over.
