GNGTS 2024 - Atti del 42° Convegno Nazionale

Session 1.1 GNGTS 2024 Fig.1 – a) The entre 2009 QF seismicity with at least 6 P- and 4 S arrival tmes (blue dots) relocated by using Hypoellipse with an optmised 1D-velocity model. The best locatons (selectng criteria are specifed in the upper lef corner of the map) are shown. Red triangles are the seismic statons used by QF for the locatons. Dark grey lines represent the main faults of the area. Pink lines are the evidence of surface rupture during the L’Aquila 2009 seismic sequence. Black straight lines are traces of vertcal cross sectons; b) some of the most interestng vertcal sectons (strike N°50E) showing the depth distributon of the seismic events occurred within ± 0.8 km distance from the sectons; c) above, the magnitude vs tme diagram and histogram of magnitude values; botom) histograms showing the number of P- and S- waves, RMS (s), ERH (km), ERZ (km) and GAP (°).
