加卸载响应比与应变能加速释放的临界现象讨论

Abstract

Abstract: Both LURR- (Load-Unload Response Ratio) anomalies and best-fit power-law function of ARSE (accelerating release of strain energy) are computed using data for a range of distances from the epicenters of 8 earthquakes occurred in the mainland of China. The result shows that there is a linear relation between the logarithm of either the critical region radius (R) for ARSE or the region radius (R) for optimal LURR and the magnitude of the events. A strong correlation is evident between the ARSE and LURR critical region size suggesting that these two observations have a common physical mechanism. It means that the seismogenic system closes to critical status.

Key words: Critical point hypothesis, Accelerating release, Load-Unload Response Ratio, Seismogenic zone
