Exactly.
Because the sensors are mounted on that very land.
So tectonic movement will certainly have an effect. And you can see remnants of earthquakes in some of the data.

> As a result of melting ice, the land has continued to rise yearly in Scandinavia, mostly in northern Sweden and Finland, where the land is rising at a rate of as much as 8–9 mm per year, or 1 m in 100 years. This is important for archaeologists, since a site that was coastal in the Nordic Stone Age now is inland and can be dated by its relative distance from the present shore.
