Abstract

Records of an IRIS broadband seismic station (AAK) deployed in the Tien Shan area were studied. An STS-1 seismometer made it possible to investigate ground motion velocity in the range of a few minutes. The result was to identify asymmetric anomalies in seismic noise that differ from Earth tidal variations. These indicate the effects of local tectonic processes during some time intervals. Several large earthquakes occurred near the seismic station during the days that the anomaly was observed. The seismic noise anomalies and statistically significantly earthquakes were found to be coincident with increased amplitudes of air pressure variations.

局部构造变形和附近同期地震

摘要

研究了在天山地区部署的IRIS宽带地震台站（AAK）的记录。STS-1地震仪使研究几分钟内的地面运动速度成为可能。结果是确定与地球潮汐变化不同的地震噪声中的非对称异常。这些表明在某些时间间隔内局部构造过程的影响。在观测到异常期间，地震台附近发生了几次大地震。发现地震噪声异常和统计上显着的地震与气压变化幅度的增加相吻合。
