Hítardalur gagnvirkt þrívíddar landlíkan

Displacements in Fagraskógarfjall for some time before the landslide fell - 24.7.2018

Sentinel-1 satellite radar images show displacement in the starting area before July 7th, when the landslide occurred according to InSAR analysis by Vincent Drouin at the University of Iceland and the National Land Survey of Iceland. The mountainside in the starting area of the landslide is different from the surrounding slopes according to an interferometric analysis of the radar images. The displacement in the last days before the landslide was at least a few centimetres. The starting area also appears to have been moving in 2017, 2016, and 2015 but at a slower rate.

A large landslide falls in Hítardalur valley - 10.7.2018

A large landslide fell in Fagraskógarfjall mountain in Hítardalur valley, W-Iceland, in the morning of July 7th. The landslide crossed the river Hítará, damming the river and causing a lake to form above the debris tongue. The water found a new channel the next day into Tálmi, a riverbed that reconnects with Hítará a few km farther downstream.

The landslide fell from an area that showed evidence of earlier ground displacements and might be an old landslide deposit. The displaced material is a mixture of e.g. rock debris, scree from the lower part of the hillside, swamp soil and sediments from ancient lakes on the valley bottom. A preliminary estimate of the volume of the slide is 10–20 million m3. The area of the debris tongue is ca. 1,5 km2 and the debris is up to 20–30 m thick.

Fractures in Svínafellsheiði and a potential rockslide on Svínafellsjökull - 22.6.2018

Civil Protection advises against travel on Svínafellsjökull due to landslide danger. In particular, guided tours on the glacier are discouraged. Travellers are advised to stop only for a short while at viewpoints by the glacier tongue.

IMO and The Icelandic Civile Protection Agency reassess the status for Öræfajökull - 4.5.2018

It is close to nine months since an unrest in Öræfajökull was detected. The unrest was apparent from elevated seismicity, the development of a depression in the ice-surface (cauldron) within the caldera, and the presence of geothermal gases from a glacial river. At this time, the geothermal activity beneath Öræfajökull was assessed to be high relative to previous decades.

Glaciers in Iceland continue to retreat - 20.4.2018

The mass balance of the Icelandic glaciers has been negative since 1995 with the exception of the year 2015 when it became positive for the first time in 20 years. The mass balance in 2016 was again negative by a similar magnitude as in recent years. The mass balance of Langjökull and Hofsjökull

was again negative in 2017 whereas Vatnajökull was almost in balance. The glaciers have lost approximately 250 km3 of ice since 1995, which corresponds to ca. 7% of their total volume. Glaciers in Iceland have retreated rapidly for more than two decades and glacier downwasting is one

of the most obvious consequences of a warming climate in the country.

EUROVOLC – a networking project kick-off meeting - 26.2.2018

A group of more than 70 Earth and atmospheric scientists from 9 European countries met earlier this month in Keflavik to start their collaboration on the Horizon2020 Infrastructure project EUROVOLC. The group represents 18 partners comprising volcano research and monitoring institutions, civil protection and companies from the IT and geothermal industry.

The weather in Iceland in 2017 - 23.2.2018

The year 2017 was warm in Iceland and the weather was mainly favourable. February, May, September and October were particularly warm. The East had unusually much precipitation. Heavy rainfall in the East and Southeast at the end of September resulted in extensive flooding from major rivers in the area. The last two months of the year were considerably cooler than the previous months. November was cold and the last days of December were the coldest days of the year. Wind speed was slighly lower than average.

Seismic swarm east of Grímsey on the decline - 23.2.2018

The seismic swarm east of Grímsey has been on the decline for the last days. Substantial seismic activity is however still ongoing with small swarms occurring, including up to magnitude M3 earthquakes. This night, February 23, two magnitude M2.8 earthquakes where detected about 13 km north of Grímsey.

Seismic swarm near Grímsey: update 15:00, 19 February - 19.2.2018

At 05:38 UTC this morning an earthquake of magnitude M5.2 occurred 14 km ENE of Grímsey. It was felt widely in the Northern part of the country. Five more earthquakes were detected. The earthquakes originate from the so-called Grímsey oblique rift zone in the northern Skálfandadjúp basin within the Tjörnes fracture zone.

Ice cave in Hofsjökull – a warning - 15.2.2018

Ice caves are often found at glacier edges in Iceland, formed either by meltwater flow beneath the ice or by geothermal activity. News has recently been shared about a newly discovered ice cave in Blágnípujökull, where a child has collapsed due to breathing in toxic gases. The cave should not be entered without gas monitoring instruments.

IMO's Involvement in WMO's Global Cryosphere Watch - 25.1.2018

Three years ago, the World Meteorological Organization approved the implementation of the Global Cryosphere Watch as a cross-cutting mechanism to bring together international observations and research of the world's cryosphere. Its data products and services are intended to support scientific progress and environmental policy developments related to the cryosphere, including snow cover, glaciers, ice caps, permafrost, sea ice, freshwater ice and icebergs around the globe.

Final estimates of the emissions from the Holuhraun eruption based on ground-based measurements - 22.1.2018

A new paper published last week in Geosciences reports that the Holuhraun eruption released the most SO2 (sulfur dioxide) of any effusive (non-explosive) eruption in the world on an annual basis since 1978, the advent of satellite monitoring of volcanic eruption clouds. The Holuhraun eruption released 16 times more SO2 (sulfur dioxide, 9.6 Mt) and almost twice as much CO2 (carbon dioxide, 5.1 Mt) as one year´s worth of anthropogenic emissions within Iceland (0.06 Mt SO2 and 3 Mt CO2 in 2015).  Read more
