Ziel der Reise / Objectives of Cruise:
The Gulf of Cadiz and the Horseshoe abyssal plain to the south and southwest of the Iberian Peninsula are characterized by diffuse seismic and tectonic activity and the region lacks a clear plate boundary separating Africa from Eurasia/Iberia. The area hosted with the Great Lisbon earthquake of 1755 the largest European earthquake that was ever reported in historic times. The exact location of the source of the 1755 Lisbon earthquake, however, is still unknown. A small network of ocean-bottom-seismometers (OBS) was deployed during the RV Poseidon cruise POS430 in April 2012 in the Horseshoe abyssal plain and across the Horseshoe fault, recording local earthquakes over a time period of approx. 6 month. OBS were now recovered with RV Poseidon during its cruise POS440 in October 2012. On Saturday October 13, 2012 Poseidon left the harbour of Lisbon. Between October 14 and October 17 all OBS were recovered and Poseidon reach the port of Faro on October 18, 2012.
