Feb 8, 2024 · We show that massive magma flow into dikes can be established with only modest overpressure in a magma body if a large enough pathway opens at its boundary and gradual …

Feb 23, 2024 · Volcanologists recently analyzed the structure of the region’s underground magma system and found that pent-up tectonic stress drove ultrafast magma flow within a 15 …

Aug 29, 2019 · By combining flow and deformation modeling using COMSOL Multiphysics, we for the first time present a quantitative model that links magma ascent to deformation. We quantify …

Feb 28, 2023 · We hypothesize that the form of magma flow is controlled by the forces acting on the dike (e.g., buoyancy, source pressure, fracture pressure) and test this through analogue …

Jan 30, 2014 · Neogene regional mafic dykes extending north of the Álftafjörður central volcano in east Iceland are studied to test models of dyke swarm emplacement at spreading ridges. This …

Dec 9, 2006 · When tectonic stresses close to a magma chamber have been largely relieved, then extrusion of magma may start. The model pattern of dike propagation and extrusion is …

Feb 8, 2024 · We show that massive magma flow into dikes can be established with only modest overpressure in a magma body if a large enough pathway opens at its boundary and gradual …

May 23, 2018 · New research by Spaans and Hooper explores how mechanical stress caused by the two plates moving apart contributed to magma emplacement during an eruption of …

Feb 8, 2024 · We show that massive magma flow into dikes can be established with only modest overpressure in a magma body, if a large enough pathway opens at its boundary, and gradual …

Jan 1, 2015 · The regional tectonic palaeo-stress field is deduced to cause oblique spreading across the Álftafjörður dyke swarm and govern a subhorizontal dextral shear component on …
