Definition of microseism in English:



  • A very small earthquake, less than 2 on the Richter scale.

    ‘The microseisms are located and the data is used to create maps of the hydraulic fracture geometry.’
    • ‘Collectively, these ocean microseisms have an annual cumulative seismic energy comparable to that generated from earthquakes, said Kedar.’
    • ‘Scientists believed that microseisms are generated when the large ocean waves of hurricanes interfere or strike a coastline.’
    • ‘The phase velocities of microseisms recorded with an array of eight instruments are measured in four different locations.’
    • ‘Based on experimental data it is shown, that the hypothesis of resonant amplification of microseisms in the resonator between daylight surface and oil reservoir is more adequate.’
