| Date: | 2006 |
| Abstract: | Textural, mineralogical and geochemical analyses of near-surface sediments from six different stations offshore SW Iberian Peninsula revealed the presence of thin detrital intervals corresponding to very fine-grained turbidites. Precise dating of the two most recent sedimentary layers based on ²¹⁰ Pb and ¹³⁷ Cs geochronology provides ages of 1971 ± 3 AD and 1908 ± 8 AD. These ages correspond to high-magnitude historical and instrumental earthquakes that occurred in the region: the 1969 Horseshoe Earthquake (Mw 8. 0) and the 1909 Benavente Earthquake (Mw 6. 0). Such a good correlation between turbidites and high-magnitude (Mw. |
