Southern Peninsula (Icelandic: Suðurnes, Icelandic pronunciation: [ˈsʏːðʏrˌnɛːs] ⓘ) is an administrative unit and part of Reykjanesskagi (pronounced [ˈreiːcaˌnɛsˌskaijɪ]), or Reykjanes Peninsula, a region in southwest Iceland. It was named after Reykjanes, the southwestern tip of Reykjanesskagi.[1]

The region has a population of 27,829 (2020) and is one of the more densely populated parts of the island. The administrative centre is Keflavík, which had 7,000 residents when it merged with the nearby town of Njarðvík and Hafnir in 1995 to create Reykjanesbær, which is the largest settlement outside the Greater Reykjavík area; in 2018 the region had a population of 17,805.[2] The region is the location of Keflavík International Airport, the major point of entry for Iceland.[3][4] Some fishing towns, such as Grindavík, Njarðvík and Sandgerði, are situated on the peninsula.

The peninsula is marked by active

geothermal power station at Svartsengi. Near the power station a luxury spa and pool area has been installed using the hot and mineralized water coming down from the power station; it is known as the "Blue Lagoon" (Bláa Lónið).[6]

The Bridge Between Continents spans the Álfagjá [ˈaulvaˌcauː] rift valley (60 feet (18 m) wide and 20 feet (6.1 m) deep) near Grindavík, which is promoted to tourists as marking the boundary between the Eurasian and North American tectonic plates. It was built in 2002 and previously named Leif the Lucky bridge in honor of Icelandic explorer Leif Eriksson who traveled from Europe to America nearly 500 years before Christopher Columbus.[7]

A great deal of volcanic unrest was occurring in this part of the Reykjanes Peninsula from 2020 onward, after nearly 800 years of inactivity. After the eruption of the

Main article: Geology of Reykjanes Peninsula

The Southern Peninisula contains the south western portion of the Reykjanes volcanic belt, where the continuation of the

Eldey volcanic system, rise above sea level. The Reykjanes volcanic belt has between 3 and 6 volcanic systems (depending on author -see map for 6 system on land classification of the Reykjanes, Svartsengi, Fagradalsfjall, Krýsuvík, Brennisteinsfjöll, and Hengill volcanic systems). These are closely spaced en-echelon fissure systems, extending across the Reykjanes Peninsula.[12][13][14][15]). Each volcanic system on the peninsula consists of (volcanic and tectonic) fissures and faults directed mostly NE-SW and may have other features such as lava fields and postglacial basaltic crater rows. Only the Hengill volcanic system, the most eastern system, has an additional central volcano, but this is outside the Southern Peninsula.[16][17] Tephra deposits from offshore explosive Holocene eruptions have been preserved on the Reykjanes Peninsula.[13]
