The precursory electric signals, observed before the Izmit Turkey EQ (Mw = 7.6, August 17th, 1999), analyzed in terms of a hypothetically pre-activated, in the focal area, large scale piezoelectric mechanism
摘要：
在Izmit Turkey大型EQ之前，VOL Earth的电场监测站点在希腊记录了所产生的preseeping电信号。为了解释它们的特殊性质和它们的产生机制，假设一个大规模的压电机制，启动在伊兹米特孕震区很久之前的EQ发生的时间。所采用的物理模型的理论分析证明了一些特定的电信号，可以从焦点区域发射的岩层破坏之前的生成。VOL监测中心登记的原始数据的处理显示存在与预期理论信号相似的信号。因此，可以得出结论，早在伊兹米特EQ事件发生之前，一个大规模的压电机制就已经启动，该机制也受到潮汐触发的岩石圈振荡的调制，因此产生了观测到的地震前电信号。所采用的压电模型提供了关键的信息发生时间的孕震区岩层故障，因此，一个真正的短期时间预测的大EQ的可能性。在电场三角剖分和岩石圈地震能量流模型（LSEFM）的框架下，讨论了其它两个预测EQ参数：位置和震级。
英文摘要：
The generated, prior to the Izmit Turkey large EQ, preseismic electric signals were recorded in Greece by the VOL Earth's electric field monitoring site. In order to explain their peculiar character and their generating mechanism, a large scale piezoelectric mechanism was assumed that was initiated in the Izmit seismogenic region long before the EQ occurrence time. The theoretical analysis of the adopted physical model justifies the generation of a number of specific electric signals that can be emitted from the focal area before the rock formation failure. The processing of the registered by the VOL monitoring site raw data revealed the presence of similar signals as the expected theoretical ones. Therefore, it is concluded that long before the Izmit EQ occurrence a large scale piezoelectric mechanism was initiated that was modulated too by the tidally triggered lithospheric oscillation and therefore generated the observed preseismic electric signals. The adopted piezoelectric model provides critical information about the time of occurrence of the seismogenic area rock formation failure and therefore the possibility for a real short-term time prediction of a large EQ. The other two predictive EQ parameters, location and magnitude, are discussed in the frame of electric field triangulation and the Lithospheric Seismic Energy Flow Model (LSEFM).
