Fig. 1.4 Schematic diagram of possible failure models, their moment tensors, beachballs, and
corresponding positions in the Hudson plot [22]
1.4 Pre-alarming of Microsiesmic Events with Large
Magnitude and Disaster Control
1.4.1 Statistical analysis of Precursors for Induced Seismicity
in Mines [27]
In order to monitor the sequence evolution, the seismic sequence is analyzed
with the aim of detecting changes in statistical parameters describing the seismic
event occurred before the main shocks. The acquisition and processing of the
multiple monitoring data is shown in Fig. 1.5.
(1) The Gutenberg-Richter magnitude-frequency relationship is used to calculate
the Minimum Magnitude of Completeness (Mmin), a, and b in an area [30]:
log N = a − bM W
