M²S - Microseismic Monitoring System
M²S is a microseismic monitoring system based on the integration of geophysical data developed with national technology. The system was specifically designed for the monitoring and safety of geotechnical structures such as dams and slopes.

Microseismic Monitoring
Approaches:
1
Conventional approach monitoring natural and anthropogenic active sources from seismograms to obtain seismic source parameters;
2
Passive approach, in which ambient noise is used, based on the seismic interferometry technique to monitor the variation in speed in the environment.
