Microseismic monitoring is a seismic technique based on the identification, classification and analysis of low magnitude events recorded in seismic stations.
Conventional approach monitoring natural and anthropogenic active sources from seismograms to obtain seismic source parameters;
Passive approach, in which ambient noise is used, using the seismic interferometry technique to monitor the velocity variation in the medium.
How to monitor?
Constant measurements of the parameters:
Peak Ground Velocity (PGV)
Peak Ground Acceleration (PGA)
Integration of different methods
Location of weaknesses and events
