Description
Summary:The results of processing synchronous records from two laser strainmeters, a broadband seismograph, a laser nanobarograph, and a laser meter of hydrospheric pressure variations are discussed. It is established that the sharp change in the atmospheric pressure, which was recorded by a laser nanobarograph, resulted in the generation of solitary waves in the hydrosphere detected by the laser meter of hydrosphere pressure variations. These waves were accompanied by intense deformational perturbations with periods of about 2–2.5 min observed by the laser strainmeters and broadband seismograph. The identification of this phenomenon as a meteotsunami is supported by the subsequent arrival of powerful 1.5-h oscillations in the zone of the location of instrumental complexes, which were recorded by the laser nanobarograph and laser strainmeter.
