While the eruption at the Sundhnúksgígar crater row, southeast of Litla-Skógfell, Iceland continues on July 18, 2025, the eruptive activity has declined in the last 24 hours.
A fissure eruption began at the Sundhnúksgígar crater row, southeast of Litla-Skógfell, Iceland, around 03:54 UTC on July 16, 2025. The eruptive fissure is approximately 700–1 000 m (2 300–3 280 feet) long and appears to be propagating northward, with lava flowing southeast and no immediate threat to infrastructure.
A glacial outburst flood has been developing in the Leirá syðri and Skálm rivers, southern Iceland, following rising water levels and electrical conductivity measured since July 7, 2025. Conditions continued to intensify as of 15:00 LT on July 9.
A Level 3 severe weather outbreak is sweeping across Europe with destructive hail, damaging winds, flash floods, and potential tornadoes impacting multiple countries on June 4, 2025.
Low-level seismic tremor detected at Grímsfjall in recent days indicates possible internal water movement within the Grímsvötn subglacial lake system, southeast Iceland. The last eruption of this volcano took place in 2011 (VEI 4).
A record-breaking heatwave affected Iceland from May 6 to 15, 2025, with temperatures reaching 26.6°C (79.9°F) at Egilsstaðir Airport and setting a new national May temperature record. The 10-day event was described by the Icelandic Meteorological Office as the most significant May heatwave in the country’s meteorological history.
A new volcanic eruption has just begun north of the dam near Grindavík, Iceland, the Icelandic Met Office (IMO) reported at 09:45 UTC. A Coast Guard helicopter was sent to confirm the exact location and size of the eruption. This is the 11th eruption on the Reykjanes Peninsula since 2021 and the 9th on the Sundhnúk crater series.
An earthquake swarm began off Reykjanestá, Iceland at 14:30 UTC on March 12, 2025, with more than 104 events by 18:20 UTC.
Magma accumulation beneath Svartsengi has reached its highest recorded level since the beginning of the ongoing eruption series in December 2023. The volume of magma beneath Svartsengi is now greater than what was recorded before the November 2024 eruption.
Magma accumulation beneath Svartsengi has reached a critical volume, matching the levels observed during the last eruption on November 20, 2024. A volcanic eruption could occur at very short notice, potentially within days or weeks, according to the IMO. The IMO has revised its hazard assessment which remains in effect until February 25.
