Research on microseismic event imaging based on waveform clustering analysis
矿业科学学报, 2022 The quality of microseismic data greatly affects the accuracy of the source location results, especially in surface microseismic data where the first arrivals of P waves and S waves are not obvious or the low signal-to-noise ratio signals are difficult ...

Research on automatic picking of microseismic first arrival
Gong-kuang zidonghua, 2020 Accurate picking of the first arrival of microseisms is the prerequisite for the estimation of source location. The traditional manual picking method is inefficient and time-consuming.

Velocities of Long Period Surface Waves and Microseisms and Their Use in Structural Studies : Part I. Mantle Love and Mantle Rayleigh Waves and the Structure of the Earth's Upper Mantle. Part II. Microseisms and Their Application to Seismic Exploration [PDF]
, 1963 Part I: Phase velocities of Love waves from five major earthquakes are measured over six great circle paths in the period range of 50 to 400 seconds. For two of the great circle paths the phase velocities of Rayleigh waves are also obtained.

Tracking cave shape development with microseismic data [PDF]
Proceedings of the Fourth International Symposium on Block and Sublevel Caving, 2018 Microseismic monitoring is routinely used by block and panel caving mines worldwide to track cave shape development. The standard practice is to use the cloud of seismic event locations as a proxy for cave growth below. Careful seismic sensor array planning overcomes problems with event location reliability due to seismicray bending around the unknown ...
