Abstract In the last 130 years, Icelandic glaciers have experienced significant mass loss, and numerous paraglacial slope failures been documented in country. One such failure occurred late February 2013, when a large landslide fell onto Svínafellsjökull outlet glacier southeast Iceland. Digital elevation models aerial imagery were used to quantify glacial changes leading up event, reconstructing processes that during effects of debris on surface. Between 1994 thinning glacier‐retreat...
Landslide mapping and analysis are essential aspects of hazard risk analysis. Landslides can block rivers create landslide-dammed lakes, which pose a significant for downstream areas. In this research, we used an object-based image approach to map geomorphological features related changes assess the applicability Sentinel-1 data fast creation post-event digital elevation models (DEMs) landslide volume estimation. We investigated Hítardalur landslide, occurred on 7 July 2018 in western...
Abstract Calderas are subcircular depressions with near-vertical walls, which often gravitationally unstable and prone to mass movements that sequentially widen their basins. However, the details of these erosional changes difficult decipher due short observational periods. Here, we use a photogrammetric dataset nearly 80 years study landslide-prone south-eastern wall Askja caldera (Iceland). We analyzed aerial data from 1945 1987, stereo satellite 2013 2022, drone images acquired in 2019,...

Since the end of Little Ice Age in late 19th century Iceland’s glaciers have experienced dramatic mass loss. Thinning outlet are exposing oversteepened rock slopes, which sometimes adjust form slow slope deformations that can occasionally result catastrophic paraglacial failures. Especially around country’s deglaciating central volcanoes large landslides occurred past decades. We describe a cluster gravitational movements margin Svínafellsjökull glacier...
Anne Schöpa et al. (2018) report on an analysis of seismic signals released by the Askja July 2014 rockslide, 10 Central Iceland, and conclude from their that volume material displaced slide was 35-11 80 million m³ centre mass horizontally 1260±250 m vertically 12 430±300 m.Referring to Gylfadóttir (2017) as source, they state 12-50 13 according geodetic surveys.We note rockslide 14 ( 2017) actually reported 20 based field measurements include multi-beam 15 surveys bottom Lake Askja, lake...
<p>Over the last decades climate has warmed up worldwide and changes have occurred in general weather patterns. Where increase temperature rapidly been gathering pace decade. These also observed Iceland. From 1980 to 2015 average 0,47°C per decade precipitation increased from 1500 mm/year around 1600-1700 mm/year. The resulted more frequent thawing periods rainfall events during winter months, especially lowlands.</p><p>Mass movements,...
<p>On February 27<sup>th</sup> 2013 a large landslide fell onto Svínafellsjökull glacier, on the western slope of Öræfajökull volcano, SE Iceland. The slide occurred during an intensive rainstorm event between 24<sup>th</sup> and 27<sup>th</sup>. was detected at 20:30 o’clock seismic station located several kilometres...
