Sundhnúkur

picture info	Sundhnúkur Sundhnúkur () is a volcanic hill, within its associated Sundhnúksgígar crater row and volcanic fissures ( ) in the Svartsengi volcanic system, part of the Reykjanes Peninsula rift zone of Iceland. It is the location of the 2023–2024 Sundhnúkur eruptions. Geology The region has basalt lava shields with the larger ones being tholeiitic and smaller ones being picritic or tholeiitic. The hills are hyaloclastite table mountains or ridges and pillow lava mounds. The previous lava eruption from the Sundhnúkur crater row has been dated at , and was of basaltic aā type. The lava field that erupted prior to 2023 extends north-east from Grindavík in the south with the fissures and Sundhnúksgígar crater row extending at strike of 35°. This takes the fissure system past the older mountains of Hagafell to its east and Svartsengisfell to its west. The crater row is usually now classified as part of the Eldvörp–Svartsengi or Svartsengi volcanic system which is pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	2023–2024 Sundhnúkur Eruptions The 2023–2024 Sundhnúkur eruptions ( is, Eldgosin við Sundhnúksgíga 2023–2024) are an ongoing series of volcanic eruptions in the Southern Peninsula (Iceland), Reykjanes Peninsula, near the town of Grindavík, Iceland. , there have been six eruptions between December 2023 and August 2024, following an intense series of earthquakes. Although localised, the seismic and volcanic activity have caused significant disruption across the western part of the peninsula, especially for the town of Grindavík. The eruptions were preceded by an intense earthquake swarm in the Eldvörp–Svartsengi, Eldvörp–Svartsengi volcanic system that began on 24 October 2023, caused by a Igneous intrusion, magmatic intrusion underneath the area. The frequency and intensity of the earthquakes dramatically increased on 10 November 2023, with around 20,000 tremors recorded by that time, the largest of which exceeded magnitude 5.3. An evacuation was ordered in Grindavík, and large-scale subsidence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Sundhnúksgígar Sundhnúksgígar () or Sundhnúkagígar are volcanic craters east of Eldvörp–Svartsengi in the island nation of Iceland. They are named after Sundhnúkur, which is a hill just south of Sundhnúksgígar. The craters are aligned in a row called ''Sundhnúksgígaröðin''. The first eruption in the crater row took place about 2000 years ago. In December 2023, as part of the Sundhnúkur eruptions, some craters began to erupt. On 14 January 2024, a second eruption began as a result seismic activity that began from the Sundhnúksgígar craters. By July 2024 there had been five eruptions.

picture info	Eldvörp–Svartsengi Eldvörp–Svartsengi (); "fire cones–black meadow" in Icelandic language, Icelandic also Svartsengi volcanic system) is a volcanic system in the southwest of Iceland on the Southern Peninsula (Iceland), Southern Peninsula, southeast of Keflavík International Airport and north of the town of Grindavík. Made up of fissures, cones and volcanic craters, it had been relatively inactive for several centuries until 2020, when the first in a series of magmatic intrusions occurred. In December of 2023 the fourth such intrusion culminated in 2023–2024 Sundhnúkur eruptions, an eruption, with further eruptions in 2024. Geography Location Eldvörp–Svartsengi is located in the southwest of Iceland, in the west of the Southern Peninsula, which forms the southwest tip of the country. The Icelandic toponym Svartsengi, literally "black meadow", designates a small valley at the foot of Sýlingarfell. From here, Keflavík and its eponymous international airport are to the northwest, the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
