he results of instrumental observations of the acoustic effectscaused by stronger earthquakewiththe magnitude mb= 5.7 whichoccurred in Iran on July 08, 2019are given. The observations were carried outat three pointes: Geophysical observatory "Mikhnevo" (54.94°N; 37.73°E), Center forgeophysical monitoringin Moscow (55.70° N; 37.57° E) of SadovskyInstitute of Geosphere DynamicsofRussian Academy of Sciences and at a pointlocated in Zvenigorodtown, Moscow Region (55.69°N; 36.77°E), which provided the bearing to the source of acoustic signals. Digitalseries of atmospheric pressure and microbaric variationsare obtained by measurements using a Davis Vantage Pro 2 automated digital weather station and MB-03 microbarometerare used as intimal data. In order to isolate useful signals in the analysis of microbaric variations, we used the Multi-Channel Correlation Method which made it possible to isolate low-amplitude coherent wave signals against incoherent microbaric noise.It is shown that the earthquake caused atmospheric disturbancesin the form of propagating in the stratospheric waveguide acoustic vibrations in infrasonic frequency band which were registeredat distances exceeding 2700 km, as well as microbaric variations caused by seismic wavesthat came to the point of acoustic detection. The characteristic periods of acoustic signals caused by earthquakes are given. The energies of the acoustic source and the earthquake are estimated from the spectral characteristics of the infrasound signal propagating in the stratospheric waveguide. [ABSTRACT FROM AUTHOR]
