Iceland is bracing for an imminent volcanic eruption on the Reykjanes Peninsula. A magma tunnel, stretching approximately 15 kilometers between Grindavík and Sundhnúk, is regarding to release extremely hot lava flows, threatening nearby communities, a power plant is an industrial site intended…) vital and an emblematic tourist destination.
This geological phenomenon, known as a magmatic dike, is the cause of thousands of earthquakes and has caused significant deformation of the ground, opening chasms and cracking buildings and roads. Faced with this threat, local residents were evacuated.
The Icelandic Meteorological Association (IMO) warns of an almost certain volcanic eruption. Experts even suggest that this eruption might mark the start of a more explosive and secular eruptive phase for the region.
On October 25, seismic activity began to intensify, with thousands of earthquakes in a few hours (The hour is a unit of measurement:), including two of magnitudes 3.9 and 4.5. This instability continued, including a 4.8 magnitude earthquake on November 9. These events are caused by the intrusion of magma into the dyke at several points, with the tunnel having been mapped on November 11 with magma at a minimum depth of 800 meters.
Benjamin Andrews, a geologist at the Smithsonian Institute’s National Museum of Natural History and director of the Global Volcanism Program, explains that the dyke rests on an underground fissure in the tectonic plate. under Iceland (Iceland, (in Icelandic Ísland, literally “land of…). If this crack continues to grow and the magma comes close enough to the surface (A surface generally refers to the surface layer of ‘an object. The term a…), an eruption is probable.
Malcolm Hole, volcanologist at the University of Aberdeen, indicates that the lava, with a temperature of between 1100 and 1200 degrees Celsius, usually emerges slowly from the ground. It follows the terrestrial topography, thus facilitating its movement prediction. Thorvaldur Thordarson, professor of volcanology at the University of Iceland, predicts that the majority of the lava will head west and into the sea. amplitude (In this simple wave equation:) of the eruption might resemble that of Fagradasfjall in 2021, which lasted more than six months.
Currently, it is impossible to accurately predict whether the eruption will occur in the coming hours, days or weeks. Edward W. Marshall, a researcher at the Nordic Volcanology Center at the University of Iceland, estimates that if there is an eruption, it might occur anywhere from a few days to three weeks. After this time, cooling might begin to close the fractures.
