“…That by Bragato and Slejko (2005) is one of them and, as already mentioned, is consistent with the preliminary results presented by Bommer et al (2007). Additionally, it satisfies 8 out of the 10 criteria proposed by Bommer et al (2010), the remaining two being of lesser importance since the model will be employed in only part of the magnitude range.…”

“…Since one of the objectives of the work was to capture this spectral amplification, the sampling provided by Ambraseys et al (2005), smaller than other attenuation models and consistent with that of Bragato and Slejko (2005), was considered more appropriate. Additionally it is consistent with the model by Bragato and Slejko (2005), with which it will be combined. In relation to the magnitude, it is not important that the model by Ambraseys et al (2005) does not include the non-linear magnitude dependence proposed by Bommer et al (2010), because it will only be used in part of the magnitude range.…”

Abstract. The seismic hazard of the Iberian Peninsula is analysed using a nonparametric methodology based on statistical kernel functions; the activity rate is derived from the catalogue data, both its spatial dependence (without a seismogenic zonation) and its magnitude dependence (without using Gutenberg-Richter's relationship). The catalogue is that of the Instituto Geográfico Nacional, supplemented with other catalogues around the periphery; the quantification of events has been homogenised and spatially or temporally interrelated events have been suppressed to assume a Poisson process.The activity rate is determined by the kernel function, the bandwidth and the effective periods. The resulting rate is compared with that produced using Gutenberg-Richter statistics and a zoned approach. Three attenuation relationships have been employed, one for deep sources and two for shallower events, depending on whether their magnitude was above or below 5. The results are presented as seismic hazard maps for different spectral frequencies and for return periods of 475 and 2475 yr, which allows constructing uniform hazard spectra.

“…The finding that all rejected GMMs overestimate the spectral values could be explained by the fact that the tested GMMs all were derived using mainly records from earthquakes with larger magnitudes than the earthquakes used in this study and ground motions from small earthquakes decay more rapidly than those from large earthquakes (e.g. Ambraseys et al, 2005;Bragato & Slejko, 2005;Pousse et al, 2006). The ranking list presented by Scherbaum et al (2004) shows a high degree of consistency with the results from the present study (see Table 3).…”

“…The background noise is a limiting factor since it can mask seismic signal, especially in the low-frequency band. The importance of noise level reduction on seismic data is strongly linked to quantify the detection level of the network, that reflects directly on the completeness magnitude of an area and indirectly on the calibration of attenuation relations through regression analysis, which may be biased by non-triggering stations (McLaughlin, 1991;Bragato and Slejko, 2005).…”

Abstract. The Centro di Ricerche Sismologiche (CRS, Seismological Research Centre) of the Istituto Nazionale di Oceanografia e di Geofisica Sperimentale (OGS, Italian National Institute for Oceanography and Experimental Geophysics) in Udine (Italy) after the strong earthquake of magnitude M=6.4 occurred in 1976 in the Italian Friuli-Venezia Giulia region, started to operate the North-eastern Italy Seismic Network: it currently consists of 17 very sensitive broad band and 18 simpler short period seismic stations, all telemetered to and acquired in real time at the OGS-CRS data centre in Udine. Real time data exchange agreements in place with other Italian, Slovenian, Austrian and Swiss seismological institutes lead to a total number of about 100 seismic stations acquired in real time, which makes the OGS the reference institute for seismic monitoring of North-eastern Italy. The south-western edge of the OGS seismic network (Fig. 1) stands on the Po alluvial basin: earthquake localization and characterization in this area is affected by the presence of soft alluvial deposits. OGS ha already experience in running a local seismic network in high noise conditions making use of borehole installations in the case of the micro-seismicity monitoring of a local gas storage site for a private company. Following the ML = 5.9 earthquake that struck the Emilia region around Ferrara in Northern Italy on 20 May 2012 at 02:03:53 UTC, a cooperation of Istituto Nazionale di Geofisica e Vulcanologia, OGS, the Comune di Ferrara and the University of Ferrara lead to the reinstallation of a previously existing very broad band (VBB) borehole seismic station in Ferrara. The aim of the OGS intervention was on one hand to extend its real time seismic monitoring capabilities toward South-West, including Ferrara and its surroundings, and on the other hand to evaluate the seismic response at the site. We will describe improvements in running the North-eastern Italy Seismic Network, including details of the Ferrara VBB borehole station configuration and installation, with first results.
