Crater rows 230 m / 755 ft
Reykjanes peninsula (SW Iceland), 63.89°N / -22.52°W
Current status: restless (2 out of 5)
Last update: 29 Nov 2023 (Smithsonian / USGS Weekly Volcanic Activity Report)

Reykjanes volcano on the peninsula of the same name is a vast fissure system in SW Iceland. It is located where the Mid Atlantic Ridge emerges onto land.
It forms a vast area with many eruptive fissures, lava fields, hot springs and mud pools. In 2000, a large earthquake lowered the water level in Lake Kleifarvatn by 5 metres, but has gradually returned to normal since then.

Background

The Reykjanes volcanic system at the SW tip of the Reykjanes Peninsula, where the Mid Atlantic Ridge rises above sea level, comprises a broad area of postglacial basaltic crater rows and small shield volcanoes.
The Reykjanes volcanic system is the westernmost of a series of four closely-spaced fissure systems that extend diagonally across the Reykjanes Peninsula. Most of the volcanic system is covered by Holocene lavas and eruptions have occurred in historical time during the 13th century at several locations on the NE-SW-trending fissure system.

Reykjanes volcano (Reykjanes Peninsula) - Smithsonian / USGS Weekly Volcanic Activity Report for 22 November-28 November 2023 (New Activity / Unrest)

On 22 November the Icelandic Meteorological Office (IMO) lowered the Aviation Color Code for Reykjanes to Yellow (the second level on a four-color scale), noting that seismicity associated with the magmatic dike intrusion had decreased during the previous week. Although inflation continued to be detected at Svartsengi, they determined that the likelihood of an eruption had decreased. During 22-27 November seismic activity was relatively stable at a rate of about 500 earthquakes per day, with most events concentrated near Sýlingarfell and Hagafell. ... Read all
