Exploring the Consistency of Data Collected in Archaeological Geophysics: A Cas...
Pro, C.; Caldeira, B.; Tena, M. T.; Charro, C.; Oliveira, R. J.; Borges, J.; Mayoral, V.Different geophysical methods applied at the settlement of Villasviejas del Tamuja (Botija, Spain) have identified robust anomalies located at the same position, but some anomalies are reflected by only one method. Furthermore, analysing the spatial correlation of these anomalies is of fundamental importance for obtaining a correct archaeological interpretation. In this work, we analysed the main results of ele...
Reply to Comment on “The earthquakes of 29 July 2003, 12 February 2007, and 17 ...
Pro, C.; Bezzeghoud, M.; Buforn, E.; Udias, A.H.Indeed, the Lisbon earthquake is a very unusual seismic event and an exception to the rule because most great tsunami-generating earth- quakes are related to well-defined subduction zones. The epicentral region, focal mechanism and the structures involved at the origin of this earthquake are still a matter of debate, with several models having been proposed (e.g. Baptista et al., 2003; Grandin et al., 2007a,b; ...
The earthquakes of 29 July 2003, 12 February 2007, and 17 December 2009 in the ...
Pro, C.; Buforn, E.; Bezzeghoud, M.; Udias, A.The Cape Saint Vincent region is of major seismological interest for its tectonic complexity and for the occur- rence of the great 1755 Lisbon earthquake. No structure capable of generating such a large earthquake has yet been convincingly identified, but all authors agree that there is a possibility of a similar earthquake occurring offshore of the Cape sometime in the future. To shed some light on the region'...
Sismicidad y Sismotectónica del SW de Iberia
Pro, C.; Buforn, E.; Udias, A.; Bezzeghoud, M.The Cape Saint Vincent (SW Iberia) region is of major seismological interest for its tectonic complexity and for the occurrence of the great 1755 Lisbon earthquake that affected the Iberian Peninsula and produced extensive damage generating a large tsunami too. We here examine the mechanism of the three largest earthquakes to have occurred in the last 40 years west of the Cape – 29 July 2003 (Mw=5,3), 12 Februa...
The ALERT-ES Project: an Earthquake Early Warning System for S. Iberia
Buforn, E.; Carranza, M.; Udías, A.; Goula, X.; Colom, Y.; Roca, A.; Zollo, A.; Lozano, L.; Pro, C.; Carrilho, F.; Hanka, W.; Madariaga, R.The main goal of the ALERT-ES project (“Sistema de Alerta Sísmica Temprana: Aplicación al Sur de España”) is to study the feasibility of an Earthquake Early Warning System (EEWS) for SW Iberian Peninsula applied to the potentially damaging earthquakes that occur in the region of Cape S. Vicente-Gulf of Cadiz. This area is characterized by the occurrence of large earthquakes with damage in SW Iberia, such as tho...
Mechanism of 2003, 2007 and 2009 earthquakes (S. Vicente Cape) and implications...
Buforn, E.; Pro, C.; Bezzeghoud, M.; Udias, A.The San Vicente Cape region (SW Iberia) is of great seismological interest due to its tectonic complexity and for the occurrence of the 1755 Lisbon mega-earthquake. A structure capable of generating such large earthquake has not been convincingly found but authors agree with the possible occurrence in the future of a similar earthquake offshore of San Vicente Cape.We have studied the mechanism of three earthqua...
The 1980, 1997 and 1998 Azores earthquakes and its seismotectonic implications
Borges, J.F.; Bezzeghoud, M.; Buforn, E.; Pro, C.; Fitas, A.We have studied the focal mechanisms of the 1980, 1997 and 1998 earthquakes in the Azores region from body-wave inversion of digital GDSN (Global Digital Seismograph Network) and broadband data. For the 1980 and 1998 shocks, we have obtained strike– slip faulting, with the rupture process made up of two sub-events in both shocks, with total scalar seismic moments of 1.9 × 1019 Nm (Mw = 6.8) and 1.4 × 1018 Nm (M...
