Gulf of Koper The Gulf of Koper or Koper Bay (, , ) is located in the northern part of the Adriatic Sea, and is a part of the Gulf of Trieste. The gulf, named after the city of Koper, is part of the Slovene Riviera and is entirely located in Slovenian territory. Crossed by the river Rižana, it is 18 km² large and spans from Debeli Rtič, next to the borders with the
Gulf of Aqaba thereof and thence Westward on a parallel (27°54'N) to the coast of the Sinaï Peninsula". The gulf is one of two gulfs created by the Sinai Peninsula's bifurcation of the northern Red Sea, the Gulf of Suez lying to the west of the peninsula and the Gulf of Aqaba to its east. Geologically, the gulf forms the southern end of the Dead Sea Transform. It contains three small pull-apart basins, the Elat Deep, Aragonese Deep and Dakar Deep, formed between four left lateral strike-slip fault segments. Movement on one of these faults caused the 1995 Gulf of Aqaba earthquake. Trade
