2023–2025 Sundhnúkur Eruptions
The 2023–2025 Sundhnúkur eruptions () are a series of volcanic eruptions on the Southern Peninsula (Iceland), Reykjanes Peninsula, near the town of Grindavík, Iceland. Between December 2023 and April 2025, there have been eight eruptions, following an intense series of earthquakes in November 2023. Although localised, the seismic and volcanic activity have caused significant disruption across the western part of the peninsula, especially for the town of Grindavík. However, the Capital Region (Iceland), Capital Region, including Reykjavík, has remained physically unaffected. 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 Richter ...

Magma
Magma () is the molten or semi-molten natural material from which all igneous rocks are formed. Magma (sometimes colloquially but incorrectly referred to as ''lava'') is found beneath the surface of the Earth, and evidence of magmatism has also been discovered on other terrestrial planets and some natural satellites. Besides molten rock, magma may also contain suspended crystals and volcanic gas, gas bubbles. Magma is produced by melting of the mantle (geology), mantle or the Crust (geology), crust in various tectonics, tectonic settings, which on Earth include subduction zones, continental rift (geology), rift zones, mid-ocean ridges and Hotspot (geology), hotspots. Mantle and crustal melts migrate upwards through the crust where they are thought to be stored in magma chambers or trans-crustal crystal mush, crystal-rich mush zones. During magma's storage in the crust, its composition may be modified by Fractional crystallization (geology), fractional crystallization, contaminati ...

Reykjanes Volcanic Systems
Reykjanes () is a small headland on the south-western end of the Reykjanes Peninsula in Iceland, giving the main peninsula its name. Volcanic action is responsible for forming the entire peninsula. The nearest town is Keflavik. The name, , translates to "smoking point,” , and . It is named this due to the continuing volcanic activity of the Reykjanes volcanic belt; there are also many other uses of this name in Iceland, e.g. the Reykjanes Peninsula or Reykjanes in Ísafjarðardjúp. Geography The region is about to the south of Iceland's international airport. It is about 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 high. Other volcanic systems of the Reykjanes volcanic belt could affect the Reykjanes region and have erupted as recently as April 2025. Other hills associated with the system are Skálafell (Grindavíkurbær) with a height of in the south-west near the se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
