(Wiley-Blackwell, 2017-05)A large rockslide was released from the inner Askja caldera into Lake Askja, Iceland, on 21 July 2014. Upon entering the lake, it caused a large tsunami that traveled about ∼3 km across the lake and inundated the shore with vertical runup measuring up ... -
(MDPI AG, 2019-02-26)The Holuhraun lava flow was the largest effusive eruption in Iceland for 230 years, with an estimated lava bulk volume of ~1.44 km3 and covering an area of ~84 km2. The six month long eruption at Holuhraun 2014–2015 generated a diverse surface environment. ...

(Springer Nature, 2017-09-07)Growing evidence for significant magmatic vesiculation prior to magma-water interaction (MWI) has brought into question the use of ‘diagnostic’ features, such as low vesicularities and blocky morphologies, to identify hydromagmatic pyroclasts. We address ...
-
(European Association of Geochemistry, 2015)The effusive six months long 2014-2015 Bárðarbunga eruption (31 August-27 February) was the largest in Iceland for more than 200 years, producing 1.6 ± 0.3 km3 of lava. The total SO2 emission was 11 ± 5 Mt, more than the amount emitted from Europe ...

(Elsevier BV, 2017-06)The 6-month long eruption at Holuhraun (August 2014–February 2015) in the Bárðarbunga-Veiðivötn volcanic system was the largest effusive eruption in Iceland since the 1783–1784 CE Laki eruption. The lava flow field covered ~84 km2 and has an estimated ...

(MDPI AG, 2020-03-31)Roughness can be used to characterize the morphologies of a lava flow. It can be used to identify lava flow features, provide insight into eruption conditions, and link roughness pattern across a lava flow to emplacement conditions. In this study, we ...
-
(Elsevier BV, 2018-09)It is well established that rootless cones and associated deposits are the result of explosive interactions between lava flows and environmental water, but there is substantial uncertainty about the dynamics of rootless eruptions, particularly the ...
-
(IOP Publishing, 2016-01-19)Iceland is well known for its volcanic activity due to its location on the spreading Mid Atlantic Ridge and one of the earth’s hot spot. In the past 1000 years there were about 200 eruptions occurring in Iceland, meaning volcanic eruptions occurred ...

(Elsevier BV, 2017-12)In the 60th year after the placing of the corner stone under the Polish Polar Station at Hornsund (PPSH; Spitsbergen, Svalbard, Norway), a new capsule has been laid down in the vicinity of the PPSH. It is made of stainless steel, and includes five ...
-
(MDPI AG, 2018-01-20)A new lava field was formed at Holuhraun in the Icelandic Highlands, north of Vatnajökull glacier, in 2014–2015. It was the largest effusive eruption in Iceland for 230 years, with an estimated lava bulk volume of ~1.44 km3 covering an area of ~84 km2. ...
-
(IOP Publishing, 2019-04-29)This study used optical remote sensors to identify surface hydrothermal alteration and thermal anomalies in Krýsuvík geothermal field. Multispectral Landsat and ASTER satellite images were used to identify hydrothermal alteration minerals and thermal ...
-
(Wiley-Blackwell, 2015-09-23)The 2014–2015 Bárðarbunga-Veiðivötn fissure eruption at Holuhraun produced about 1.5 km3 of lava, making it the largest eruption in Iceland in more than 200 years. Over the course of the eruption, daily volcanic sulfur dioxide (SO2) emissions exceeded ...
-
(IOP Publishing, 2019-08-14)In the beginning of December 2017, Mt. Agung eruption powered down to minor ash emissions and on the middle of December, aerial photographs of the crater were taken by Indonesia Centre of Volcanology and Geological Hazard Mitigation (PVMBG) showing a ...
