“…The catalogue consists of two parts: (a) 1000-1899, compiled from historical earthquake data and from information gathered in the Archive of Historical EArthquake Data (AHEAD) (Locati et al 2014) after reassessing all earthquake parameters, based either on raw macroseismic data or on existing, selected regional catalogues (GomezCapera et al 2014);and(b) 1900-2006, harmonised from existing national catalogues and numerous special studies as described in Grünthal and Wahlström (2012) and Grünthal et al (2013). The catalogue was extended to cover Central and Eastern Turkey for a more homogeneous hazard analysis.…”

The 2013 European Seismic Hazard Model (ESHM13) results from a community-based probabilistic seismic hazard assessment supported by the EU-FP7 project "Seismic Hazard Harmonization in Europe" (SHARE, 2009(SHARE, -2013. The ESHM13 is a consistent seismic hazard model for Europe and Turkey which overcomes the limitation of national borders and includes a through quantification of the uncertainties. It is the first completed regional effort contributing to the "Global Earthquake Model" initiative. It might serve as a reference model for various applications, from earthquake preparedness to earthquake risk mitigation strategies, including the update of the European seismic regulations for building design (Eurocode 8), and thus it is useful for future safety assessment and improvement of private and public buildings. Although its results constitute a reference for Europe, they do not replace the existing national design regulations that are in place for seismic design and construction of buildings. The ESHM13 represents a significant improvement compared to previous efforts as it is based on (1) the compilation of updated and harmonised versions of the databases required for probabilistic seismic hazard assessment, (2) the adoption of standard procedures and robust methods, especially for expert elicitation and consensus building among hundreds of European experts, (3) the multi-disciplinary input from all branches of earthquake science and engineering, (4) the direct involvement of the CEN/TC250/SC8 committee in defining output specifications relevant for Eurocode 8 and (5)

“…Souriau & Granet 1995;Souriau & Pauchet 1998;Souriau et al 2001). The largest historical earthquake is the 1660 Bagneres-de-Bigorre earthquake (21/06/1660) with a moment magnitude of M W 6.1 ± 0.1 (Cara et al 2008) or M W 6.4 ± 0.3 (Stucchi et al 2013;Locati et al 2014). The seismicity is located inside the upper crust at depths shallower than 15 km (Fig.…”

S U M M A R YLocal seismic networks are usually designed so that earthquakes are located inside them (primary azimuthal gap <<180• ) and close to the seismic stations (0-100 km). With these local or near-regional networks (0• -5 • ), many seismological observatories still routinely locate earthquakes using 1-D velocity models. Moving towards 3-D location algorithms requires robust 3-D velocity models. This work takes advantage of seismic monitoring spanning more than 30 yr in the Pyrenean region. We investigate the influence of a well-designed 3-D model with station corrections including basins structure and the geometry of the Mohorovicic discontinuity on earthquake locations. In the most favourable cases (GAP < 180• and distance to the first station lower than 15 km), results using 1-D velocity models are very similar to 3-D results. The horizontal accuracy in the 1-D case can be higher than in the 3-D case if lateral variations in the structure are not properly resolved. Depth is systematically better resolved in the 3-D model even on the boundaries of the seismic network (GAP > 180• and distance to the first station higher than 15 km). Errors on velocity models and accuracy of absolute earthquake locations are assessed based on a reference data set made of active seismic, quarry blasts and passive temporary experiments. Solutions and uncertainties are estimated using the probabilistic approach of the NonLinLoc (NLLoc) software based on Equal Differential Time. Some updates have been added to NLLoc to better focus on the final solution (outlier exclusion, multiscale grid search, S-phases weighting). Errors in the probabilistic approach are defined to take into account errors on velocity models and on arrival times. The seismicity in the final 3-D catalogue is located with a horizontal uncertainty of about 2.0 ± 1.9 km and a vertical uncertainty of about 3.0 ± 2.0 km.

“…This survey and the subsequent efforts to rebuild Lisbon as an earthquake-safe city are commonly described as the birth of modern seismology and earthquake engineering (Mineiro, 2005). Other significant historical earthquakes in Portugal include the intraplate 1531 M 6.5-7.1 Lower Tagus Valley earthquake, the 1858 M 6.8-7.2 Setúbal earthquake, and the 1909 M 6 Benavente earthquake (Martins and Mendes Víctor, 2001;Stich et al, 2005;Vilanova and Fonseca, 2007;Stucchi et al, 2013;Baptista et al, 2014;Locati et al, 2014 Figure 1.

Over the past decade, scientists have been called to participate more actively in public education and outreach (E&O). This is particularly true in fields of significant societal impact, such as earthquake science. Local earthquake risk culture plays a role in the way that the public engages in educational efforts. In this article, we describe an adapted E&O program for earthquake science and risk. The program is tailored for a region of slow tectonic deformation, where large earthquakes are extreme events that occur with long return periods. The adapted program has two main goals: (1) to increase the awareness and preparedness of the population to earthquake and related risks (tsunami, liquefaction, fires, etc.), and (2) to increase the quality of earthquake science education, so as to attract talented students to geosciences. Our integrated program relies on activities tuned for different population groups who have different interests and abilities, namely young children, teenagers, young adults, and professionals.
