| 英文摘要 | We systematically analyzed the benioff strain release before 65 earthquakes with m-s over 6.0 in china from 1978 to 2003 to investigate the generality of the widely discussed accelerating moment release (amr) phenomenon before strong and intermediate-strength earthquakes. in this approach, a strong or intermediate-strength earthquake is selected as a ``target earthquake,'' and retrospective analysis of seismic activity before the ``target earthquake'' is performed. simple searching area (three circular areas with different radius centered at the epicenter of the ``target earthquake'') and unified temporal range (8 years) are taken in the analysis. justification of whether amr exists is by both visual inspection and by power-law curve fitting. it is found that more than 3/5 of the earthquakes under consideration exhibit clear pre-shock amr property, and 1/3 of the events seem to be sensitive to the searching area. amr behavior shows apparent focal mechanism dependence: 15 out of 17 dip-slip earthquakes with stable moment release characteristics against the changing of searching areas exhibit amr behavior, while 16 out of 25 strike-slip earthquakes with stable moment release characteristics exhibit amr behavior. |
