The subglacial lake Grímsvötn in central Vatnajökull ice cap (Iceland), collects surface meltwater as well produced by volcanic and powerful geothermal activity. is released jökulhlaups almost annually recent times. flood route out of beneath its seal has been at similar location since 1996 when a massive jökulhlaup (net volume 3.6 km3 ~40,000 m3 s-1 peak discharge) caused an eruption north the drained via new route. Here we present bedrock map 6...
This paper presents new estimates of the dimensions and impact 1967 Steinsholtshlaup in Iceland order to understand better event, hazards it generated, its long-term legacy implications for both landscape interpretation hazard planning areas contemporary valley glaciation. On 15th of January a major rockslide occurred on northern face Innstihaus mountain southern Iceland, which overlooked glacier called Steinsholtsjökull. The slide during intensive snowmelt, that followed...
Arctic regions are warming at more than double the global average rate, causing significant changes in cryospheric and hydrologic patterns. As glaciers retreat, meltwater can accumulate expanding proglacial lakes, which often form overdeepened basins with large storage capacities steep valley walls that prone to paraglacial slope failures. If a mass movement event such as rockfall or landslide enters lake, water drain glacial outburst flood, significantly modifying landscape. Moreover, many...
Abstract. Glacier retreat is projected to increase with future climate warming, elevating the risk of mass movement-triggered glacial lake outburst floods (GLOFs). These events are an emerging yet understudied hazard in Iceland, including at Fjallsjökull, outlet glacier Vatnajökull ice cap southeast Iceland. A multibeam sonar scanner survey revealed that proglacial Fjallsárlón significantly expanded from 1945 2021. If recent terminus rates continue, will reach its maximum extent around 2110,...
Glacial outburst floods (jökulhlaups) have been a significant driver of landscape evolution, environmental change, and geohazards throughout the Quaternary. Iceland experiences more frequent jökulhlaups than nearly anywhere else on Earth, though most research focuses subglacial volcanogenic that drain across outwash plains. Abundant geomorphologic evidence exists for largescale drained along modern-day course Hvítá River in southwestern during early Holocene deglaciation, originating from...
<p>Glacial lake outburst floods (GLOFs) have occurred across the planet throughout Quaternary and are a significant geohazard in Arctic alpine regions today. Iceland experiences more frequent GLOFs—known Icelandic as jökulhlaups—than nearly anywhere on Earth, yet most research focuses triggered by subglacial volcanic geothermal activity. However, from proglacial lakes may be better analogue to global...
One of the most visible consequences climate changes in Iceland are retreating outlet glaciers and formation proglacial lakes. It is estimated that Icelandic have lost about 16% their mass since 1890 or over a 130-year time interval. Temperatures been fluctuating this period with exceptional warm 1920s 1930s followed by slightly colder interval until beginning 1980s. During glacier retreated considerably but around 1970 begun to readvancing which continued 1995. At end 20th century another...
Arctic regions are warming at more than double the global average rate with significant impacts on glaciers and hydrologic systems. Iceland is front line of this rapid climate change, a predicted loss ~20% its current ice cap volume by 2100. Much meltwater stored in proglacial lakes outlet glaciers, which risk draining glacial lake outburst floods (GLOFs). Most contemporary have been triggered subglacial eruptions geothermal activity; however, GLOFs resulting from mass movement events into...
<p>Glacial outburst floods (jökulhlaups) have significantly modified landscapes across Earth throughout the Quaternary and are a contemporary geohazard in glaciated regions worldwide. Iceland experiences more frequent jökulhlaups than nearly anywhere on Earth, though research has focused triggered by subglacial volcanic eruptions. However, from ice-marginal lakes may be better analogue for most global because both occur during rapid warming. As...
<p>On the 15<sup>th</sup> of January 1967, a rockslide, approximately 20 million m<sup>3</sup> in volume, fell from Mt. Innstihaus on to Steinsholtsjökull outlet glacier, located northern side Eyjafjallajökull ice cap South Iceland. The rockslide onto western glacier and broke up its snout. Part material into proglacial lake, front margin, causing large GLOF down Steinsholtsdalur valley. Huge...
<p>Glacial outburst floods (jökulhlaups) have occurred across Earth throughout the Quaternary, often leaving a geomorphologic, sedimentological, and climatic legacy that extends far beyond source region can persist for millennia. Furthermore, they pose an increasing geohazard in glaciated landscapes worldwide due to climate-driven ice retreat. Iceland experiences more frequent jökulhlaups than nearly anywhere on Earth, though most research focuses...
