Microseismic Motion As Affected by a Typhoon

This paper is concerned with the study of microseismic motion in the upper crustal layer as inferred from in situ data recorded by laser interferometric instruments and a broadband seismometer during the passage of typhoons in 2018 through 2020. Our analysis has revealed a relationship between the periods of microseisms as recorded by the laser strainmeter and sea swell as recorded by a laser meter of hydrosphere pressure variations.
