the moon and its influence on the earths gravity. Also the earth is spinning, so its like sloshing water around a glass delicately.

WRONG! Normal waves (i.e. not tsunami) are built up by the wind blowing across the water's surface. The Moon (and Sun) control the tides, not waves. The Earth's rotation does NOT "slosh" the sea about. [Tsunami are thrown up by undersea earthquakes or, less commonly, major sediment slides down steep slopes.]

Preceding an earthquake, stresses accumulate in the earth's crust over time, causing energy to be stored in the form of elastic strain (like that in a compressed spring). Ultimately this accumulated stress exceeds the shear strength of the crust in the fault zone causing a sudden brittle failure or rupture. This in turn causes movement and a sudden release of the stored elastic strain energy in the form of seismic waves.
