Yesterday morning, July 7 at 04:38, an earthquake measuring 3.4 in magnitude was recorded just southeast of Árnes in Þjórsárdalur. Considerable aftershock activity has followed the quake. The earthquake occurred on the South Iceland Seismic Zone, in a known fault area. The last earthquake of similar magnitude in this area occurred in January this year.
A swarm began on Reykjanes Ridge just after 9 this morning. Over 60 events have been detected, the largest events a M3.2, but the activity has decreased since noon. Swarms are common in this area.

Earthquake activity throughout the country is described in a weekly summary that is written by a Natural Hazard Specialist. The weekly summary is published on the web every Tuesday. It covers the activity of the previous week in all seismic areas and volcanic systems in the country. If earthquake swarms are ongoing or significant events such as larger earthquakes have occurred during the week, they are specifically discussed. More

The last few days there has been measured an increase in conductivity in Leirá syðri which flows from Mýrdalsjökull. We ask people to be careful at the source of the river and near river channels, due to possible gas pollution in the area.
Due to malfunction we have turned off the service publishing hydrological data on the map. Instead see the data using our Real-time monitoring system.

Update 1. July
Uplift and earthquake activity are ongoing in the Svartsengi area, with stable activity levels in recent weeks. On average, about 10 micro-earthquakes are detected per day, most of them located north of Grindavík.
No substantial changes have been detected in measurements that would prompt a reassessment of the hazard level. However, continued magma accumulation could increase the likelihood of a magma intrusion or volcanic eruption in the coming autumn.
In May 2025, an unusually intense heatwave struck Iceland and eastern Greenland, breaking numerous temperature records. On 15 May, Iceland's national May temperature record was set at 26.6°C at Egilsstaðir Airport, with several locations recording temperatures up to 13°C above the monthly average.
A new international analysis by the World Weather Attribution group shows that human-induced climate change made this heatwave around 40 times more likely and, on average, three degrees Celsius hotter than it would have been without global warming. The study also suggests that if global temperatures rise by 2.6°C, such heatwaves could become at least twice as frequent and two degrees hotter.

reached or exceeded 20°C at several weather stations for 10 consecutive

May temperature records were repeatedly broken at weather stations across the country.
A new national May temperature record of 26.6°C was set at Egilsstaðir Airport on May 15th.

Deformation measurements clearly show that uplift beneath Svartsengi is ongoing. The current uplift rate is faster than that observed following previous eruptions. This may be explained by the large volume of magma — around 30 million cubic meters — that was released from the system during the most recent event.
However, it is still too early to predict how the rate of magma accumulation will develop. Past events have shown that accumulation rates typically decline as more time passes between eruptions. At least a week, and possibly several weeks, will need to pass before we can evaluate if — and how — the rate of accumulation will change.

GPS deformation data shows that magma continues to accumulate beneath Svartsengi, although the pace of land uplift has slightly decreased in recent weeks. Despite the slower uplift, experts still consider it likely that a magma intrusion and/or eruption will occur along the Sundhnúkur crater row.
Read moreAt around 14:30 yesterday (12 March 2025), a rather intense earthquake swarm began offshore Reykjanestá. The swarm was most intense at the beginning when about 50 – 60 earthquakes were recorded in the first few hours. As the day progressed, the activity decreased but then increased again shortly before midnight when an earthquake of magnitude 3.5 occurred. When the activity increased again in the evening, it shifted slightly westward as the image shows (blue circles indicate the location of earthquakes that occurred at the beginning of the swarm yesterday, while yellow and red ones show earthquakes from late last evening and night).

These include time series of weather-related factors, such as temperature, rainfall, air pressure and solar and cloud cover, time-series on hydrology, glaciology, sea-ice condition, earthquakes, floods, ice and sediment load in rivers. Such data from IMO is important, providing a benchmark for assessing ongoing changes in the Arctic region.
