1岩石破裂以及破裂前信号的演变显示文摘地震是大量的岩石破裂事件。很多大地震之前都存在瞬态信号:电磁信号、磁场变化、电离层扰动、土壤导电率的变化以及其他震前信号。令监测人员奇怪的是,在震前短时间内一些震前信号会衰弱甚至消失不见。岩石中应力活化电流的发现提供了一个可能的解释,应力能够激活岩石中的移动电荷载体,即电子空位缺陷(electron va-cancy defects,EVD),也称空穴,用h.表示。h.相当于O2-中的O-,且以电钝性及休止的状态存在于无应力岩石中。当被激活时,h.沿着应力梯度方向流动,从而产生电流。在非常高的应力速率下,位错累积成微破裂,这正是灾变破裂的开始。当h.电荷载体无法再被激活时,震前破裂信号会明显衰弱。Freund F T Dahlgren R P Chu J j 张祯(译) 田家勇(校) 2011国际地震动态2011,,1:4
