Period is Going to be Faster When the Earth-Moon Distance Increased According to IERS Actual Data

摘要

If a small body of mass (m) orbits a large body of mass (M) then, the sidereal rotation period of the large body (M) may be calculated by the rotational equation.The earth rotation period is going to be faster when the earth-moon distance increased according to IERS actual data. Earthquakes of the upper range are distinctly related to rotational parameters of the Earth lunar declination.The earthquakes increased when the lunar declination is moving toward the earth equator (when the earth rotation are going to be faster).A perfect correlation between lunar declination and the changes of leap seconds.(UT1-UTC)-(UT1- UTC).A very good correlation between earthquakes and the changes of leap seconds.(UT1-UTC)-(UT1-UTC).The Earth rotation acceleration of 29 degree declination is more that of 18.6 declination, this lead to more earthquakes in 29 degree lunar declination.
