The recent seismic activity in Iceland, particularly around Grindavík, indicates a significant threat of volcanic eruption due to magma intrusion. As of November 2023, over 1,000 earthquakes have been recorded, with the most intense activity occurring at depths of 3-5 km. The Icelandic Civil Defense Agency has ordered evacuations in Grindavík as magma approaches the surface, with concerns about potential damage to critical infrastructure, including the Svartsengi geothermal power plant and the Blue Lagoon resort. The situation remains dynamic, with ongoing monitoring and assessments from the Icelandic Meteorological Office.

As of 16 March 2024, there have been four eruptions between December 2023 and March 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.
The eruptions were preceded by an intense earthquake swarm in the Eldvörp–Svartsengi volcanic system that began on 24 October 2023, caused by a magmatic intrusion underneath the area.
https://www.msn.com/en-us/weather/t...n-iceland-prompt-mass-evacuations/vi-AA1piC6VA new volcanic eruption on the Reykjanes peninsula in southwestern Iceland has prompted mass evacuations, authorities say. The eruption began on the Sundhnuksgigarod fissure, spewing hot lava into the air and causing considerable seismic activity. The fissure, initially estimated at 1.4 kilometers, extended to 3.9 kilometers within 40 minutes, according to the Icelandic Meteorological Office. Most of the 4,000 residents of the nearby fishing village of Grindavik had already evacuated last November, and only a few remain overnight due to the frequent eruptions. Despite the volcanic activity, flights to and from Iceland are operating normally, according to Isavia, the national airport service provider.
This is the sixth eruption since December 2023, leading volcanologists to warn of a new era of seismic activity in the region. Iceland sits on the Mid-Atlantic Ridge, making it prone to volcanic activity due to the separation of tectonic plate.
GRINDAVIK, Iceland (AP) — A volcano in southwestern Iceland that has erupted repeatedly for more than a year again belched lava and smoke into the air on Tuesday, just hours after authorities evacuated the few remaining residents of a nearby fishing village.
The eruption began at 9:45 a.m. local time (0945 GMT), triggering warning sirens in the town of Grindavik where webcams showed molten rock spewing toward the community. It had subsided by late afternoon, though the volcano was still active, Iceland’s Met Office said.
