Geomorphometric analysis of the 2014-2015 Bárðarbunga volcanic eruption, Iceland
چکیده انگلیسی
The topographical analysis of the 2014-2015 Bárðarbunga eruption revealed a maximum vertical displacement of approximately −65 m and +43 m at the study area of the Bárðarbunga caldera and Holuhraun lava field respectively. With a total subsidence volume of −1.40 ± 0.13 km3 and a dense-rock equivalent (DRE) lava volume of +1.36 ± 0.07 km3, known uncertainties in volume were decreased by approximately 35% and 77% accordingly. Taking into account the calculation of rates, the temporal development of caldera collapse and lava effusion was found to exhibit a near-exponential decrease. The ratio between subsidence and DRE lava volume moreover indicated the coupling between piston collapse and magma drainage.
