Source of 1755 Lisbon earthquake and tsunami investigated

Abstract

On November 1, 1755, the city of Lisbon was completely devastated by the combined effect of a tremendous earthquake, tsunami waves, and fire. The 1755 Lisbon earthquake was the most destructive cataclysm recorded in western Europe since the Roman Republic, with an estimated earthquake magnitude Mw ∼8.5 [Martins and Mendes Victor, 1990] and estimated tsunami magnitude of Mt= Mw= 8.5. The earthquake was felt as far away as Great Britain and Finland. The tsunami hit many coastal cities along southwest Iberia and North Africa, causing heavy destruction in Tanger and Casablanca.

Sensitivity of Tsunami Scenarios to Complex Fault Geometry and Heterogeneous Slip Distribution: Case‐Studies for SW Iberia and NW Morocco

“…The bathymetric data used is the EuroMargins SWIM multibeam compilation (Zitellini et al., 2009). The TOPAS and MCS data consist of 33 profiles collected during several surveys: the 1992 ARRIFANO survey (Sartori et al., 1994), the 1993 IAM survey (Banda et al., 1995), the 1994 BIGSETS survey (Zitellini et al., 2001), the 2002 VOLTAIRE survey (Terrinha et al., 2003) and the 2006 SWIM survey (Martínez‐Loriente et al., 2013). All MCS profiles are two‐way travel time (TWTT), except for the SWIM profiles where a pre‐stack depth migration (PSDM) was applied, and the vertical scale is, hence, in depth (km).…”

“…MCS data is available at the following published articles: SWIM profiles : Bartolome et al., (2012); Martínez‐Loriente (2013); Martínez‐Loriente et al., (2013); Martínez‐Loriente et al., (2018). VOLTAIRE profiles: Banda et al., (1995); Zitellini et al., (2001); Terrinha et al., (2009). BIGSETS profiles: Zitellini et al., (2001); Zitellini et al., (2004); Vizcaino (2009); Serra et al., (2020).…”

The Late Pleistocene-Holocene sedimentary evolution of the Sines Contourite Drift (SW Portuguese Margin): A multiproxy approach

“…The shot interval was of 50 m and the sampling rate of 0.5 ms with a shooting frequency of 6, 7 and 10 s, using a 250-m length streamer composed of 3 channels and 40 hydrophones each (Hernández-Molina et al, 2014a). The BIGSETS 1998 data were obtained through 48 channels with a 1-ms sample rate (Zitellini et al, 2001). Acquisition was done with a 4-airgun system -Sodera SSI GI-GUN -with a total volume of 150 -250 in 3 , 25 m of shooting interval and a 1200-m length streamer.…”

On the Inference of Tsunami Uncertainties From Landslide Run‐Out Observations

“…MCS and sub-bottom profiler data used for this study were acquired with different configurations during multiple marine surveys: (a) the ARRIFANO survey with the R/V OGS EXPLORA in 1992 (acquisition data and processing parameters reported by Zitellini et al (1999) and Zitellini et al (2009); (b) the IAM cruise in 1993 aboard M/VGeco Sigma (Banda et al, 1995); (c) the BIGSETS survey carried out in 1998 onboard the R/V URANIA (Zitellini et al, 2001(Zitellini et al, , 2004; (d) the PD00 survey acquired by TGS-NOPEC in 2000 (Brackenridge et al, 2013;Llave et al, 2011); (e) the 2001 SISMAR cruise onboard the R/V Le Nadir (Gutscher et al, 2002); (f) the 2002 VOLTAIRE survey onboard the R/V URANIA (Terrinha et al, 2009); (g) the SWIM 2006 cruise onboard the R/V Hesperides (Bartolome et al, 2012); and (h) the INISIGHT Leg 1 (2018) and Leg 2 (2019) cruises, carried out with the R/V Sarmiento de Gamboa (Ford et al, 2020). Interpretation of the network of MCS profiles has been carried out using the "IHS Kingdom Suite" seismic interpretation software.…”
