Abstract
Abstract Quick changes of the effective atmospheric angular momentum (AAM) functions are compared with the occurence of the strong earthquakes (with a body-wave magnitude m b ≥ 6.0) and quick changes of the Earth's rotation parameters (ERP). A strong correlation exists between these changes of the AAM functions and the times of earthquakes. The quick variations of the length-of-day (LOD) (up to 0.2 msec) are induced by the variations of the axial component of the AAM functions and strongly correlate with the times of earthquakes too. Delta-like changes of the equatorial components of the AAM functions correlate with the times of earthquakes and do not correlate with quick variations of polar motion. Common periodicities exist both in the AAM functions and earthquake series.
