摘要:
九寨沟地震发生时，中国四川省内布设了 36个AETA台站，形成了小区域的监测台阵。通过研究了这些台站的震前数据，发现13个台站的数据出现了异常。其中10个台站出现地声异常，6个台站出现电磁扰动异常。同时，一种与日升日落几乎同步的电磁扰动波形-SRSS波被发现，该波形在震中周边多处出现。这些异常很可能是九寨沟地震的前兆异常。AETA台阵成功实现了单一震例下多分量多台站前兆异常的捕捉。未来拟进一步加密AETA台阵来实现更深入的研究。
Abstract:
When the Jiuzhaigou earthquake occurred，36 AETA stations were set up in Sichuan Province， forming a small regional monitoring array. In this paper，the pre earthquake data of these stations are studied， and the data of the 13 stations are abnormal. 10 stations appeared geo-sound anomalies，and 6 stations appeared electromagnetic disturbance anomalies. At the same time, a kind of electromagnetic disturbance waveform-SRSS wave，which is almost synchronous with sunrise and sunset，has been found. The waveform appears in many places around the epicenter. These anomalies may be the precursor anomalies of Jiuzhaigou earthquake. The AETA array successfully captures the precursory anomalies of multi-component and multi-station under a single earthquake case. In the future，it is proposed to increase the density of AETA array to do more in-depth research.
