Figure 11

Frequency distribution of large seismic events in LGCD (ML > 4) in time intervals referenced to approximated Xc evaluated for positive peaks

Figure 12

Frequency distribution of large seismic events in LGCD (ML > 4) in time intervals referenced to approximated Xc evaluated for negative peaks

Figure 13

Frequency distribution of very large seismic events in LGCD ML > 4.3) in time intervals referenced to approximated Xc evaluated for positive peaks

Figure 14

Frequency distribution of very large seismic events in LGCD (ML > 4.3) in time intervals referenced to approximated Xc evaluated for negative peaks

Figure 15

Modelled negative and positive peaks approximating apparent strain of the LEGN-GLOG base and velocity of the apparent strain rates’ variations. Small stars: occurrence of seismic events with magnitude ML > 4.0 and big ones with magnitude over 4.3. Distinctive periods: ts – period of maximal values of apparent strain rates, tvs – period of maximal values of strain rates velocities.

Evaluated parameters of Gaussian peak and the values are expressed in mm/m for positive and negative peaks
