A seismic source zone model for the seismic hazard assessment of the Italian territory

Spo2frag V1.0: Software for Pushover-Based Derivation of Seismic Fragility Curves

“…This hazard curve was calculated using the software REASSESS [21]. For this calculation the seismic source zones model of [22] was considered; Gutenberg-Richter [23] seismicity parameters for these zones were provided by [24], [25] and the ground motion prediction model used was that of [26]. Figure 10: Comparison of fragility functions generated by SPO2FRAG and the same fragility functions estimated by means of IDA (see also Fig.…”

Structural Modelling Issues in Seismic Performance Assessment of Industrial Steel Buildings

“…In fact, although hazard is made available by the Istituto Nazionale di Geofisica e Vulcanologia (INGV) [11] for a dense grid covering the country, such an information is only for site class A (rock), which does not correspond to the local geological conditions of the facility. Therefore, hazard curves were computed via the software described by Convertito et al [12], employing the seismic source zone model for Italy of Meletti et al [13]; the latter is also adopted for the official nationwide hazard assessment by INGV. The parameters associated to each of the zones in terms of minimum and maximum magnitude, rate of occurrence, and b-value of the Gutenberg-Richter relationships, were given by Barani et al [14].…”

The 12 May 1802 earthquake (N Italy) in its historical and seismological context

“…These folds are offset by the northward propagation of the younger external front of the north-verging Apennine thrusts to the northwest of Cremona (Fantoni et al 2004). Fantoni et al 2004), epicenter of the 1802 earthquake (CPTI04), and seismogenic source models according to ZS9 (Meletti et al 2008) and DISS3 . Individual seismogenic sources from DISS3 are shown also Due to this structural setting and to the features of the seismicity described previously, the straightforward identification of seismogenic structures results in difficulty.…”

“…The 1802 is the main event of the zone 907 of the seismogenic zonation ZS9 (Meletti et al 2008), which represents a reduced legacy of the former zone 9 in the ZS4 (Meletti et al 2000) (Figs. 2, 3), used by the Seismotectonics and Seismic Hazard Assessment of the Mediterranean Basin-SESAME project (Jiménez et al 2001), too.…”

“…1); (d) it represents a singularity in the seismicity of Northern Italy, being the only one with Mw ≥ 5.5 located west of Lake Garda in the central-northern part of the Po Plain (Fig. 2); (1981( -2002 seismicity and seismogenic source models according to ZS9 (Meletti et al 2008) and DISS3 and (e) it provides a strong evidence for stretching the seismic source 907 of the seismogenic zonation ZS9 (Meletti et al 2008) and a composite seismogenic source in the Database of Italian Seismogenic Sources, version 3 (DISS3; Basili et al 2008) toward the west (Fig. 2) to incorporate its presumed source and other, unknown, similar ones.…”
