Eruption in Sundhnúkur crater row
The eruption continues from the single vent which formed just East of Sundhnúkur, in a similar manner since 5 April. Lava continues to extrude and propagate towards the South along open channels, which are clearly visible from the cameras. The lava is also traveling longer distances from the crater through a network of closed tubes, which prevents the lava from cooling by direct contact with the atmosphere. An outbreak south of the crater flowed over defense wall number L12 the morning of 27th of April.

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 eruption at Sundhnúkur continues with one crater, just east of Sundhnúkur, remaining active as of 5 April. Lava flows travel a short distance to the south of the crater in an open lava channel but progress further in closed channels. Part of the lava field near the barrier east of Grindavík continues to thicken slowly.
Ground uplift in the Svartsengi area continues at constant rate. Analytical models suggest that the amount of magma recharged within the reservoir beneath Svartsengi, since the eruption began on 16 March, is now approaching 10 million m3, as is shown in the graph below. In previous events, magma started propagating as dike intrusions from the reservoir at 4-5 km depth towards the surface when a threshold of about 8-13 million m3 of recharged magma was reached.

Read moreYesterday (25 March) a seismic swarm occurred in the NW part of the Askja caldera. About 30 earthquakes were detected between 08.00UTC and midday. The largest earthquake detected had a magnitude M3,5 at a depth of about 5 km. Three earthquakes with magnitudes between M2 and M2,5 were also detected, the rest of the activity was characterized by smaller events. Overall, the seismic activity in the Askja has been quite stable between months and unchanged until yesterday. Looking back, we can see that earthquakes with magnitude above M3 were detected in January 2022 and October 2021.
Read moreThe weather in 2023 was mostly favorable. It was calm, dry, relatively little snow and stormy days were quite uncommon. However, the year was cooler compared to the most recent years. The average nationwide temperature was 0.1°C colder than the average temperature between 1991 and 2020, and 0.4°C colder than the average temperature of the last ten years. It was relatively coldest in the North, while the Southwest and Southern coast were relatively warmer. The weather was particularly cold in the beginning of the year and again in March. June, on the other hand was exceptionally warm in the North and East. It was the warmest June on record in many places in those regions. The year was relatively dry, with precipitation below average across most of the country. There were several dry periods during the year, such as in March and July, but there were also periods of heavy rain in between. May and June were particularly wet and gloomy in the southern and western regions.
Read moreOn 10 November 2023 the town of Grindavík in Iceland was evacuated as massive amounts of magma suddenly flowed into a magma filled crack that propagated underneath the town. Magma was emplaced in a 'vertical sheet' type intrusion in the Earth's crust. An international team of scientists explains the formation of the intrusion, and conditions for ultra-rapid flow into cracks, in a new publication in the prestigious scientific journal Science.

Since the glacial flood reached its peak in the river Gígjukvísl approximately a week ago, the water level has been decreasing and is now comparable to what it was before the flood. The seismic tremor measured on the seismometer at Grímsfjall has also declined, with seismic noise now back to normal levels. Since last week Monday, 21 earthquakes have been recorded in Grímsvötn, including two earthquakes exceeding magnitude two.
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.
