GNGTS 2024 - Atti del 42° Convegno Nazionale

Session 1.1 GNGTS 2024 Fig.2 - a) Map view of the common seismic events from QF and Valoroso et al. (2013) catalogues. The best locatons (the flters are specifed in the boxes) are ploted. The purple triangles are the common seismic statons while the red ones are the extra seismic statons used by QF (not used for the LV processing). The black straight lines are traces of vertcal cross sectons; b) some of the most interestng vertcal sectons (strike: N°50E) which show the depth distributon of the seismic events occurring within ± 0.8 km distance from the sectons; c) Snap-shot of the seismicity distributon during tme (from April to July 2009); d) histograms showing the number of P- and S-waves, RMS (s), ERH (km), ERZ (km) and GAP (°).
