“…The law shown in Figure 3a was established for local (LDG) and epicentral intensity (MSK) established for France from the common events of the SIRENE and LDG databases. This relation is compared with different relationships or correspondences proposed for the following: France by Levret et al (1994) for local magnitudes (LDG); Northwest Europe by Ambraseys (1985) for surface-wave magnitude; Mediterranean area by D'Amico and Albarello (1999); Italy for the MCS scale (Di Maro and Tertulliani, 1990) and local magnitude (Tinti et al, 1986) or surface-wave magnitude (Albarello et al, 1995).…”

In this study, we applied a probabilistic methodology to seismic hazard assessment in metropolitan France. For that purpose we determined an attenuation law adapted to the French context. This law holds for peak ground acceleration on stiff bedrock for earthquakes with local magnitudes between 2.5 and 5.6 recorded in near field (at distances between 3 and 50 km). Geological conditions are taken into account by means of a three-categories classification of lithologies based on a 1/

“…The corresponding M w have been calculated with the procedures described in Grünthal et al (2009). The SisFrance data, where h is lacking throughout, are within the 95%-confidence bounds of the corresponding master event relation, but show a distinctly different ascent, which originates in the used relation between M L , I 0 and h by Levret et al (1994). For LDG, intensities from SisFrance have been used.…”

Harmonization check of M w within the central, northern, and northwestern European earthquake catalogue (CENEC)

2009

Large data sets covering large areas and time spans, and composed from many different independent sources, raise the question of the obtained degree of harmonization. The present study is an analysis of the harmonization with respect to the moment magnitude M w within the earthquake catalogue for central, northern and northwestern Europe (CENEC). The CENEC earthquake catalogue (Grünthal et al., J Seismol, 2009) contains parameters for over 8,000 events in the time period 1000-2004 with magnitude M w ≥ 3.5. Only about 2% of the data used for CENEC has original M w magnitudes derived directly from digital data. Some of the local catalogues and data files providing data give M w , but calculated by the respective agency from other magnitude measures or intensity. About 60% of the local data give strength measures other than M w and these have to be transformed by us using available formulae or new regressions based on original M w data. Although all events are thus unified to M w magnitude, inhomogeneity in the M w obtained from over 40 local catalogues and data files and 50 special studies is inevitable. Two different approaches have been followed to investigate the compatibility of the different M w sets throughout CENEC. The first harmonization check is performed using M w from moment tensor solutions from SMTS and Pondrelli et al. (2002, 2007). The method to derive the SMTS is described, e.g., by Braunmiller et al. (2002) and Bernardi et al. (2004) and the data are available in greater extent since 1997. One check is made against the M w given in national catalogues and another against the M w derived by applying different empirical relations developed for CENEC. The second harmonization check concerns the vast majority of data in CENEC related to earthquakes prior to 1997 or where no moment tensor based M w exists. In the case, an empirical relation for the M w dependence on epicentral intensity (I 0 ) and focal depth (h) was derived for 41 master events, i.e., earthquakes, located all over central Europe, with high-quality data. To include also the data lacking h, the corresponding depth independent relation for these 41 events was also derived. These equations are compared with the different sets of data from which CENEC has been com-G. Grünthal, D. Stromeyer, R. Wahlström 614 posed and the goodness of fit is demonstrated for each set. The vast majority of the events are very well or reasonably consistent with the respective relation, so that the data can be said to be harmonized with respect to M w , but there are exceptions, which are discussed in detail.

Abstract.Tsunami propagation is analyzed for the Ligurian Sea with particular attention on the French coasts of the Mediterranean. Historical data of tsunami manifestation on the French coast are analyzed for the period 2000 B.C.-1991 A.D. Numerical simulations of potential and historical tsunamis in the Ligurian Sea are done in the context of the nonlinear shallow water theory. Tsunami wave heights as well as their distribution function is calculated for historical tsunamis and it is shown that the log-normal distribution describes reasonably the simulated data. This demonstrates the particular role of bottom irregularities for the wave height distribution function near the coastlines. Also, spectral analysis of numerical tide-gauge records is done for potential tsunamis, revealing the complex resonant interactions between the tsunami waves and the bottom oscillations. It is shown that for an earthquake magnitude of 6.8 (averaged value for the Mediterranean Sea) the tsunami phenomenon has a very local character but with long duration. For sources located near the steep continental slope in the vicinity of the French-Italian Rivera, the tsunami tide-gauge records in the vicinity of Cannes -Imperia present irregular oscillations with a characteristic period of 20-30 min and a total duration of 10-20 h. For the western French coasts the amplitudes are significantly less with characteristic low-frequency oscillations (period of 40 min-1 h).
