Stress pattern in Portugal mainland and the adjacent Atlantic region, West Iberia
The Portuguese mainland territory is located close to the Azores-Gibraltar plate boundary, in a tectonic setting responsible for significant neotectonic and seismic activities. However, few dataExpand

An example of intraplate neotectonic activity, Vilariça Basin, northeast Portugal
The Vilarica tectonic basin (NW Iberian Peninsula) is presented as an example of intraplate neotectonic activity. The regional geological setting is first introduced then followed by a brief view onExpand

The Azambuja fault: An active structure located in an intraplate basin with significant seismicity (Lower Tagus Valley, Portugal)
The Azambuja fault is a NNE trending structure located 50 km NE of Lisbon, in an area of important historical seismicity. It is sited in the Lower Tagus Basin, a compressive foredeep basin related toExpand

The 1755 Lisbon earthquake and the beginning of closure of the Atlantic
The 1755 Lisbon earthquake and tsunami had one of the highest magnitudes in the history of Europe. The source mechanism requires generation at a subduction zone. Intensity distribution and tsunamiExpand

Analysis of seismic reflection data as a tool for the seismotectonic assessment of a low activity intraplate basin – the Lower Tagus Valley (Portugal)
The Lower TagusValley is located in the Lower TagusSedimentary Basin. Occurrence ofearthquakes in the area indicates thepresence of seismogenic structures at depththat are still deficiently known dueExpand

The 1909 Benavente (Portugal) earthquake: search for the source
The Lower Tagus River Valley has been affected by severe earthquakes comprising distant events, as in 1755, and local earthquakes, as in 1344, 1531, and 1909. The 1909 earthquake was located NE ofExpand

Geophysical characterization of the Ota–Vila Franca de Xira–Lisbon–Sesimbra fault zone, Portugal
SUMMARY This paper focuses on the reprocessing of seismic reflection profiles, aeromagnetic and seismicity data, to locate and characterize the Ota‐Vila Franca de Xira‐Lisbon‐Sesimbra fault zone. TheExpand

Active tectonics in Southern Portugal (SW Iberia) inferred from GPS data. Implications on the regional geodynamics
Abstract A GPS-based crustal velocity field for the SW Portuguese territory (Algarve region, SW Iberia) was estimated from the analysis of data from a network of campaign-style GPS stations set up inExpand

Incorporating Descriptive Metadata into Seismic Source Zone Models for Seismic‐Hazard Assessment: A Case Study of the Azores–West Iberian Region
In probabilistic seismic-hazard analysis (PSHA), seismic source zone (SSZ) models are widely used to account for the contribution to the hazard from earth- quakes not directly correlated withExpand
