Mota de SáInstituto Superior Técnico, Lisbon, PortugalSines industrial complex- 13 km2 - Houses a significant number of National (Portuguese) and European Critical Infrastructures. Located next to the Atlantic Coast- 180 km away from several major seismogenic sources: (the Gorringe Bank and the Marquês de Pombal Fault) both able to raise a 8.5 to 9 magnitude earthquake, leading to Peak Ground Accelerations of about 0.20 g to 0.24 g in stiff rock soils, with the possibility of 0.4 g to 0.5 g in soft soils.- 90km away from the Lower Tagus Valley faults, able to generate magnitude 7 eventsSeismic and Tsunamigenic Zones of concernTagus River Valley (Fault complex) (90 km from Sines)Interaction of the African and Euroasiatic plates.
