Estimation of horizontal deformation rates based on tachymetric measurements: Processing measurements collected yearly in the geothermal area Bjarnarflag in North-East Iceland from 2015 to 2018

Measurements of a tachymetric network in the geothermal area of Bjarnarflag in North-East Iceland are performed during four consecutive years (2015-2018). For the yearly adjustment of the measurements an alternative iteration scheme to Baarda’s ’B-method of testing’ is proposed, because the level of significance of the F-test performed in the...
