The 1975 North Atlantic earthquake occurred on May 26 at 09:11 UTC. The epicenter was located in the North Atlantic, in an area between the Azores, Iberian Peninsula, and Morocco. It had a magnitude of Mw 7.9, or Ms 8.1.[3]
This was an intraplate earthquake that was located about 200 km south of the Gloria Fault, the presumed boundary between the African Plate and the Eurasia Plate. It had a right-lateral strike-slip focal mechanism and was unusually large for an oceanic strike-slip event.[4][5] Damage was reported in Madeira, which is about 250 km away.[6][7] A tsunami of 0.3 m in maximum water elevation was recorded in Lagos, Portugal and an eyewitness reported a 2 m (6 ft 7 in) wave height at Ponta Delgada in the Azores.[4]
