Absrtact—The results of instrumental observations of acoustic effects from a number of strong earthquakes in Albania, Greece, Iran, and Turkey with magnitudes from 5.1 to 6.9 are presented. The observations were carried out at three sites—at the Geophysical observatory “Mikhnevo” (54.94° N; 37.73° E), at the Center for Geophysical Monitoring in Moscow (CGM) (55.70° N; 37.57° Е) of the Sadovsky Institute of Geosphere Dynamics of the Russian Academy of Sciences, and at the observation site in Zvenigorod, Moscow region (55.69° N; 36.77° Е). This observation geometry provided the directions to the sources of acoustic perturbations. It is shown that earthquakes with the sources located at distances from ~1845 to ~2815 km from recording points cause perturbations in the atmosphere in the form of acoustic oscillations in infrasound range propagating in the stratospheric waveguide and in the form of acoustic oscillations caused by seismic waves. The characteristic periods of the acoustic signals caused by the earthquakes are presented. The energies of the acoustic source and the earthquake are estimated from the spectral characteristics of infrasonic signals propagating in the stratospheric waveguide.

摘要—给出了从阿尔巴尼亚，希腊，伊朗和土耳其发生的一系列强烈地震（从5.1到6.9）的声学效应的仪器观测结果。观测是在三个地点进行的：在萨米斯基斯基研究所的地球物理观测站“ Mikhnevo”（北纬54.94°；东经37.73°），在莫斯科地球物理监测中心（CGM）（北纬55.70°；北纬37.57°）。俄罗斯科学院地球动力学研究所以及位于莫斯科地区兹韦尼哥罗德（55.69°N; 36.77°Е）的观测点。这种观察几何结构为声扰动源提供了方向。结果表明，震源位于距记录点约1845至〜2815 km的位置时，会以平流层波导中传播的次声范围内的声振荡的形式以及由地震引起的声振荡的形式引起大气扰动波浪。给出了地震引起的声信号的特征周期。根据平流层波导中传播的次声信号的频谱特性，估算声源和地震的能量。
