Krísuvík is a system of eruptive fissures, craters and small basalt shields in SW Iceland west of lake Kleifarvatn, one of the active fissure swarm systems that are arranged west to east on the Reykjanes peninsula. A large eruption occurred from the Ogmundargigar fissure in 1188.

Sfondo

The Krísuvík volcanic system is a group of NE-SW-trending basaltic crater rows and small shield volcanoes cutting the central Reykjanes Peninsula west of Kleifarvatn lake.
According to the Global Volcanism database, it is part of the wider Krýsuvík-Trölladyngja volcanic system, which also includes Fagradalsfjall fissure swarm that erupted in March 2021.
The Krýsuvík-Trölladyngja system is an approximately 50-km-long composite fissure swarm trending about N38°E, including a 30-km-long swarm of fissures, with no central volcano. It is one of the volcanic systems arranged en-echelon along the Reykjanes Peninsula west of Kleifarvatn lake.
The Fagradalsfjall and Krýsuvík fissure swarms are considered splits or secondary swarms of the Krýsuvík–Trölladyngja volcanic system, however we treat Fagradalsfjall and Krýsuvík as separate systems (or volcanoes in the sense of this database).

Several eruptions have taken place since the settlement of Iceland, including the eruption of a large lava flow from the Ogmundargigar crater row around the 12th century, probably in 1188. The latest eruption at Krísuvík took place during the 14th century.
Uplift in 2009: Between May and November 2009 the area over Krisuvik Volcano was uplifted by 3 cm.

Krysuvik-Trolladyngja volcano (Reykjanes Peninsula) - Smithsonian / USGS Weekly Volcanic Activity Report for 17 August-23 August 2022 (New Activity / Unrest)

The Institute of Earth Sciences reported that lava effusion at the fissure eruption in the Krýsuvík-Trölladyngja volcanic system continued during 16-19 August. Lava erupted mainly from a central cone, containing a lava pond, and flowed SE. Measurements taken during an overflight on 16 August indicated that the flow rate had decreased to 2 cubic meters per second. ... Read all
