    Earthquakes below 7.5 or 7.0 usually do not trigger tsunamis. However, sometimes 6.0 earthquakes can trigger local tsunamis, which are smaller and less destructive. Earthquakes trigger tsunamis when aftershocks exceed magnitude 5.3 causing the land along fault lines to move up or down. When parts of the seafloor shift vertically, either becoming raised or lowered, entire water columns become displaced. This creates a "wave" of energy, which propels the water thus causing tsunamis.
