3.4 | 12 Mar 14:57:32 | Checked | 1.1 km ENE of Reykjanestá |

Yesterday, March 12th at 14:30 a seismic swarm started on Reykjanestá. More than 600 earthquakes have been detected. Six earthquakes between M3 and M3.5. The earthquakes have been felt in Grindavík.
In December 2024 an seismic swarm of similar size occurred. The main focus then was near Eldey, around 10 km SW of Reykjanestá. In August 2024 and September 2023 there also seismic swarms on the Reykjanestá. The earthquakes are likely triggered earthquakes due to increased stress on the Reykjanes peninsula in connection with the unrest the last years.

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

At 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).

Deformation measurements show that land uplift continues at the same rate as in recent weeks. Magma continues to accumulate beneath Svartsengi, and its volume has reached the highest level recorded since the eruptive series began at the Sundhnúkur crater row in December 2023.
Seismic activity in the Sundhnúkur crater row has been gradually increasing alongside magma accumulation, following a pattern similar to that observed before the November eruption.
Read moreA southerly storm or violent storm is expected later today and tomorrow, with very strong wind gusts, widely 35 – 45 m/s and especially near mountains, but locally exceeding 50 m/s. Considerable or heavy rain is expected in the south and the west regions of the country. More details can be found here.
Read moreThe year 2024 was remarkably cold compared to temperatures of this century. The national average temperature was 0.8 degrees below the 1991 to 2020 mean, and it was the coldest year since 1998. Lowest relative temperature was inland in the North, while it was warmer along the southern coast. The summer was wet across the entire country, but other months of the year were relatively dry. Overall, the year was drier than average in the eastern, southern, and southwestern parts of the country, but wetter than average in the North and West, which experienced heavy rain during summer. The sea level pressure was unusually low from June through August, and the summer was characterized by frequent low-pressure system passage and unfavourable weather. During other seasons, the weather was relatively calm, and annual mean seal level pressure and wind speed were around average.
Read moreThe first phase of the Icelandic Meteorological Office's (IMO) new website was launched today. This marks the beginning of a major project aimed at renewing both the website and its entire technical infrastructure.
The new weather forecast website is available at https://gottvedur.is/en/. While the site is still in development, once the renewal of the current website is complete, the new weather pages will be moved to the domain vedur.is.

Seismic activity continues to increase near Grjótárvatn. So far in January, nearly 100 earthquakes above M1.0 have been recorded. This is comparable to the total number of earthquakes in December 2024, which was the highest monthly count ever recorded in the area.
Read moreThe climate and hydrology of Iceland are highly variable due to natural conditions. Significant changes in these factors over the last 15 years are in harmony with the future scenarios represented and affirmed in the latest IPCC summary report, AR5. The main purpose of IMO is to contribute towards security in society by monitoring, analyzing, interpreting, informing; providing warnings and forecasts and predicting natural hazards. It is important to keep the infrastructure strong so that IMO may fulfill its role.
