Between February 2007 and April 2008, swarms of small, deep-seated earthquakes were detected within the Kverkfj\u00f6ll volcanic system (Upptyppingar) in north-eastern Iceland (Hooper et al., 2011) associated with a deep dyke intrusion.\u00a0<\/span>
\nVolcano deformation was measured using InSAR and GPS (both continuous and campaign).\u00a0<\/span>Hooper et al. (2011) states that “the continuous GPS station shows a change in velocity towards the end of April 2007, then steady deformation until March 2008 when the velocity reverts again to the background rate”<\/span>.<\/span>
\nThe authors also investigate the impact of the ice caps on measured deformationdeformation: “From the horizontal GPS data, we simultaneously estimated the background motion due to plate spreading and the thinning of the ice caps, seasonal motion due to snow loading, and the additional velocity during the intrusion”.<\/span>
\nThe authors estimate the dyke dimension as: “Strike and dip of the dyke are 81\u00b0\u201382\u00b0 and 42\u00b0\u201343\u00b0 respectively and the volume is 42\u201347<\/span>\u2009<\/span><\/span>million<\/span>\u2009<\/span><\/span>m<\/span>3 <\/sup>“.<\/p>\n","latitude":"64.65","longitude":"-1.72","images":[{"path":"\/nas\/content\/live\/cometnerc\/wp-content\/uploads\/figures_sentinel\/kverkfjoll\/kverkfjoll_147A_02466_191712.jpg","url":"https:\/\/comet.nerc.ac.uk\/wp-content\/uploads\/figures_sentinel\/kverkfjoll\/kverkfjoll_147A_02466_191712.jpg","width":501,"height":669,"mime":"image\/jpeg","size":164197,"filename":"kverkfjoll_147A_02466_191712.jpg"},{"path":"\/nas\/content\/live\/cometnerc\/wp-content\/uploads\/figures_sentinel\/kverkfjoll\/kverkfjoll_009D_02504_202119.jpg","url":"https:\/\/comet.nerc.ac.uk\/wp-content\/uploads\/figures_sentinel\/kverkfjoll\/kverkfjoll_009D_02504_202119.jpg","width":501,"height":669,"mime":"image\/jpeg","size":163434,"filename":"kverkfjoll_009D_02504_202119.jpg"},{"path":"\/nas\/content\/live\/cometnerc\/wp-content\/uploads\/figures_sentinel\/kverkfjoll\/kverkfjoll_118A_02507_211817.jpg","url":"https:\/\/comet.nerc.ac.uk\/wp-content\/uploads\/figures_sentinel\/kverkfjoll\/kverkfjoll_118A_02507_211817.jpg","width":501,"height":668,"mime":"image\/jpeg","size":100186,"filename":"kverkfjoll_118A_02507_211817.jpg"},{"path":"\/nas\/content\/live\/cometnerc\/wp-content\/uploads\/figures_sentinel\/kverkfjoll\/kverkfjoll_045A_02494_171816.jpg","url":"https:\/\/comet.nerc.ac.uk\/wp-content\/uploads\/figures_sentinel\/kverkfjoll\/kverkfjoll_045A_02494_171816.jpg","width":501,"height":669,"mime":"image\/jpeg","size":164141,"filename":"kverkfjoll_045A_02494_171816.jpg"},{"path":"\/nas\/content\/live\/cometnerc\/wp-content\/uploads\/figures_sentinel\/kverkfjoll\/kverkfjoll_009D_02597_080910.jpg","url":"https:\/\/comet.nerc.ac.uk\/wp-content\/uploads\/figures_sentinel\/kverkfjoll\/kverkfjoll_009D_02597_080910.jpg","width":501,"height":667,"mime":"image\/jpeg","size":137050,"filename":"kverkfjoll_009D_02597_080910.jpg"},{"path":"\/nas\/content\/live\/cometnerc\/wp-content\/uploads\/figures_sentinel\/kverkfjoll\/kverkfjoll_111D_02489_111313.jpg","url":"https:\/\/comet.nerc.ac.uk\/wp-content\/uploads\/figures_sentinel\/kverkfjoll\/kverkfjoll_111D_02489_111313.jpg","width":501,"height":669,"mime":"image\/jpeg","size":156128,"filename":"kverkfjoll_111D_02489_111313.jpg"},{"path":"\/nas\/content\/live\/cometnerc\/wp-content\/uploads\/figures_sentinel\/kverkfjoll\/kverkfjoll_045A_02538_121210.jpg","url":"https:\/\/comet.nerc.ac.uk\/wp-content\/uploads\/figures_sentinel\/kverkfjoll\/kverkfjoll_045A_02538_121210.jpg","width":501,"height":669,"mime":"image\/jpeg","size":140503,"filename":"kverkfjoll_045A_02538_121210.jpg"},{"path":"\/nas\/content\/live\/cometnerc\/wp-content\/uploads\/figures_sentinel\/kverkfjoll\/kverkfjoll_009D_02423_131316.jpg","url":"https:\/\/comet.nerc.ac.uk\/wp-content\/uploads\/figures_sentinel\/kverkfjoll\/kverkfjoll_009D_02423_131316.jpg","width":501,"height":669,"mime":"image\/jpeg","size":148426,"filename":"kverkfjoll_009D_02423_131316.jpg"},{"path":"\/nas\/content\/live\/cometnerc\/wp-content\/uploads\/figures_sentinel\/kverkfjoll\/kverkfjoll_111D_02490_152021.jpg","url":"https:\/\/comet.nerc.ac.uk\/wp-content\/uploads\/figures_sentinel\/kverkfjoll\/kverkfjoll_111D_02490_152021.jpg","width":501,"height":669,"mime":"image\/jpeg","size":164971,"filename":"kverkfjoll_111D_02490_152021.jpg"},{"path":"\/nas\/content\/live\/cometnerc\/wp-content\/uploads\/figures_sentinel\/kverkfjoll\/kverkfjoll_147A_02488_131211.jpg","url":"https:\/\/comet.nerc.ac.uk\/wp-content\/uploads\/figures_sentinel\/kverkfjoll\/kverkfjoll_147A_02488_131211.jpg","width":501,"height":668,"mime":"image\/jpeg","size":154823,"filename":"kverkfjoll_147A_02488_131211.jpg"},{"path":"\/nas\/content\/live\/cometnerc\/wp-content\/uploads\/figures_sentinel\/kverkfjoll\/kverkfjoll_009D_02426_131311.jpg","url":"https:\/\/comet.nerc.ac.uk\/wp-content\/uploads\/figures_sentinel\/kverkfjoll\/kverkfjoll_009D_02426_131311.jpg","width":619,"height":1050,"mime":"image\/jpeg","size":242268,"filename":"kverkfjoll_009D_02426_131311.jpg"}],"uri":"https:\/\/comet.nerc.ac.uk\/volcanoes\/kverkfjoll\/","api_endpoint":"https:\/\/comet.nerc.ac.uk\/wp-json\/volcanodb\/v1\/volcano\/3050","measurement_methods":"InSAR, GPS - continuous, GPS - campaign, Levelling, Strainmeter, Tiltmeter, EDM","inferred_causes":"Faulting\/tectonics, Retreating ice cap (Hooper et al., 2011)","references":["Smithsonian Institution Global Volcanism Program
