Spring tides occur when the moon is new or full, resulting in higher high tides and lower low tides. Neap tides follow, with moderate tides. Tides can trigger earthquakes due to stress and tidal components like normal and shear stresses. Statistical tests analyze the tidal phase angles at the time o
