Seismic observatories usually have instruments measuring three axes: north-south (y-axis), east-west (x-axis), and vertical (z-axis). If only one axis is measured, it is usually the vertical because it is less noisy and gives better records of some seismic waves. [citation needed] The foundation of a seismic station is critical. This type of research is called paleoseismology (“paleo” means old, and “seismology” is the study of earthquakes, so paleoseismology is the study old earthquakes). The basic assumption that paleoseismologists use is that what happened in the past will most likely happen again in the future.
