The recent 2007 Portugal earthquake (Mw=6.1) in the seismotectonic context of t...
Borges, J.F.; Bezzeghoud, M.; Caldeira, B.; Grandin, R.An event of magnitude Mw 6.1(EMSC) occurred on 12/02/2007 at 10:35 UTC off coast of South-Western Portugal. The earthquake had its epicentre in the eastern Horseshoe Abyssal Plain, at 175 km South-West of San Vicente Cape (Figure 1). This earthquake is the largest earthquake since the great instrumental earthquake, Ms=8.0 (USGS), occurred on February 28th, 1969 in the same epicentral area. This earthquake was f...

Borges, J.F.; Caldeira, B.; Grandin, R.; Bezzeghoud, M.; Carrilho, F.Ao longo da sua história a margem sudoeste da Península Ibérica foi palco de vários terramotos cujos efeitos produziram elevados danos materiais e perdas de vidas humanas: o sismo Lisboa de 1 de Novembro de 1755 (Mw~8.5)[1] foi o mais importante evento histórico e um dos mais devastadores sismos alguma vez descritos, quer pela destruição devida ao forte movimento do solo por ele produzido, quer pelo tsunami que...
Strong ground motion in southern Portugal due to the 1755 Lisbon earthquake
Grandin, R; Borges, JF; Caldeira, B; Bezzeghoud, MThe strong earthquake (M=8.8) that struck a large part of the Iberian Peninsula and Northern Morocco on November 1, 1755, was caused by the motion along a fault which localisation and spatial extent are still uncertain. According to recent numerical modelling of tsunami wave travel times, it seems that the tsunamigenic fault may be lo- cated off the southwestern coast of Portugal. Multi-channel seismic profiles...
Seismicity and earthquake risk in Portugal
Bezzeghoud, M.; Borges, J.F.; Caldeira, B.; Grandin, R.The workshop “Earthquake monitoring and Earthquake Risk in WEstern Mediterranean” (EERWEM) will summarize the current knowledge, on-going projects and research plans with regard to seismic activity and risk in the region. This work is organized in two topics: i) presentation of our current research on seismic activity and earthquake risk in the Western Mediterranean region, particularly in Portugal and ii) a sh...
