| 摘 要： | Comparison between the NEIC broadband radiated energy catalogue and the Harvard CMT catalogue provides information about apparent stres.In spite of its significant uncertainties and limited relability, the clues obtained from this comparison seem interestiin in the physics of earthquakes.Scaling of apparent stress provides information about the dynamic friction along an earthquake fault.Relation between reduced energy and seismic moment implies that for strike-slip earthquakes,velocity-dependent friction plays a predominant role,while for non-strike-slip earthquakes,slip-dependent friction is predominant.It is also found that strike-slip events with extremely low apparent stress tend to occur“in single”,which is applied to the prediction of the seismic tendency following the 2001 Qinghai-Xizang(Tibet) borderMW7.8 earthquake.
