Recent volcanic activity in the Svartsengi area has led to continuous land uplift, although the exact rate is still being determined through GNSS measurements. Around 200 earthquakes, the largest measuring M1.4, have been recorded near the magma conduit since yesterday. Despite a reduction in earthquake frequency, significant risks, including ground collapse, remain for the nearby Grindavík area.
A day after a new volcanic eruption started near the evacuated city of Grindavik, Iceland, authorities are reporting a reduced flow of lava. While it’s unclear how long the eruption will last, they warn new cracks may be appearing on the surface within the city in the next few days.
A new volcanic fissure eruption started at 22:17 UTC on December 18, 2023, about 4 km (2.5 miles) NE of the town of Grindavik, Reykjanes, Iceland. The eruptive fissure is about 4 km long, with the northern end just east of Stóra-Skógfell and the southern end just east of Sundhnúk.
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.
Earthquake activity continues in the Reykjanes/Svartsengi volcanic system, with around 370 earthquakes detected on May 19, 2022.
More than 3 000 earthquakes have been automatically detected near Eldvörp in the Reykjanes/Svartsengi volcanic system in the past week, the Icelandic Met Office reports. In addition, recent deformation observations identified the onset of a new inflation event west of Thorbjörn which is likely caused by magma intrusion.
Significant seismic activity has been detected on the Reykjanes peninsula, Iceland over the past 7 days. The greatest activity was at Svartsengi, where slight uplift was recorded, and in the vicinity of Grindavik.
Latest InSAR images near the Fagradalsfjall eruption site in Reykjanes Peninsula, Iceland show clear signs of deformation over the period from December 20 to 26, 2021. The deformation seen now is very similar to the deformation observed at the end of February 2021…
An intense earthquake swarm that started near the Fagradalsfjall eruption site in Reykjanes Peninsula, Iceland on December 21, 2021 — just one day after the eruption was declared officially over — continues with no signs of abating. While no new lava flows have…
An intense earthquake swarm started near Fagradalsfjall, Reykjanes Peninsula, Iceland at 17:00 UTC on December 21, 2021 — just one day after the official end of the eruption in the area, the longest in the country in more than 50 years. The Aviation Color Code was…
