Þorvaldur Þórðarson, a volcanology professor at the University of Iceland, suggests that recent earthquakes in the Reykjanes Peninsula could indicate magma accumulation under Húsfellsbruna, raising concerns about potential lava flows near Reykjavík.
The Icelandic Meteorological Office (IMO) reports a decreased likelihood of an eruption at Svartsengi following the cessation of magma inflow to the November 10 dike. While magma accumulation continues beneath Svartsengi, the immediate eruption risk along the dike has significantly reduced.
Over 700 earthquakes have been detected along the orientation of a magma intrusion in Iceland during the first 12 hours of November 14, 2023. The latest measurements show that the graben-like formation is still forming and is mechanically active.
A new update from the Icelandic Meteorological Office (IMO) at 18:30 UTC today has raised significant concerns about an imminent volcanic eruption near Grindavík on the Reykjanes Peninsula. The latest data, stemming from a crucial status meeting involving the IMO, the University of Iceland, and the Department of Civil Protection and Emergency Management, points to a substantial risk of volcanic activity in the coming days.
In response to a significant escalation in seismo-volcanic activity on the Reykjanes Peninsula in Iceland, characterized by an exceptional accumulation of magma, the intrusion of a substantial dike, and an intense earthquake swarm, the Icelandic Meteorological Office (IMO) and Civil Defense authorities have implemented critical safety protocols on November 10, 2023. These measures include the mandatory evacuation of Grindavík and the proclamation of a state of emergency
The Icelandic Met Office (IMO) has issued an update on the seismic and volcanic activity at Mt. Þorbjörn on the Reykjanes Peninsula, providing new data on the ongoing seismic unrest that began in late October. The uplift at the GNSS station has seen additional enlargements since the 7 cm rise previously reported over a 10-day period, reflecting continued subterranean pressure changes. The IMO, alongside the Civil Protection Agency, remains on high alert for signs of magma ascent, which could indicate a new phase in the volcanic activity of the area.
The Icelandic Met Office (IMO) has reported a considerable upsurge in seismic activity on the Reykjanes Peninsula, with over 18 500 earthquakes recorded since the swarm began on October 25, just north of Grindavík.
An exceptionally intense earthquake swarm lasting nearly two hours started at Þorbjörn in Iceland at 08:40 on October 31, 2023. The largest event registered an M3.7, and the activity signaled potential magma movement at depths between 1.5 km and 5 km (0.93 – 3.1 miles).
An episode of complex volcano-tectonic unrest is currently affecting the Reykjanes Peninsula, the Icelandic Met Office (IMO) said on October 29, 2023. It is interpreted to result from multiple deformation sources at depth, which are interacting and affecting a wide area across the peninsula.
Rapid land elevation near Iceland’s Fagradalsfjall volcano indicated the formation of a new magma chamber, prompting warnings of a potential volcanic eruption on the Reykjanes Peninsula in the weeks or months to come. The Icelandic Meteorological Office urged caution, especially for those planning outdoor activities in the region.
