It is about 25 km (9.7 sq mi) and includes the Reykjanes volcanic system that extends in a linear fashion up its centre continuing to the north-east as the hill of Sýrfell at 93 m (305 ft) high. Other volcanic systems of the Reykjanes volcanic belt could affect the Reykjanes region and have erupted as recently as 2024. Other hills associated with the system are Skálafell (Grindavíkurbær) with a height of 76 m (249 ft) in the south-west near the sea and Bæjarfell at 69 m (226 ft) high to its north.

Ridge. Volcanic rock production has kept pace with rift extension and subsidence with at least ten eruptions in the 14,500 years since the area became ice free after the end of the last ice age. Within the volcanic system there are active NE–SW dip-slip faults. There are two main fissure swarm zones being in the north (Stampar) and south (Sýrfell). They are separated by about 2 km (1.2 mi), and their western parts have been active in the last three eruptive periods of the
Reykjanes area.

and the two volcanic systems are very similar, even though they have separate geothermal systems,and lava composition. Recent studies tend to classify the
Reykjanes volcanic system as a separate fissure volcano of the Reykjanes volcano belt. This volcanic system marks the transition from the mainly

layers in the region. The volcano erupted for a 30 odd year period ending in 1240 CE. In 1226 CE an explosive eruption off
Reykjanes produced about 0.1 km (0.024 cu mi) of tephra with deposits up to 100 km (62 mi) away. It also has lava dated to 2150 years ago and

characteristics. While the active volcanism on the peninsula has been a major source for the geothermal activity in the area, there is evidence that the volcanism can fuel geothermal systems up to 30 kilometers away, as far as Hvalfjörður. On the
