NH2.3/AS4.29/GMPV47The 2010 flank and summit eruptions at Eyjafjallajökull volcano (Iceland): History of an eruption from source to the atmosphere (co-organized)
|Convener: Thorvaldur Thordarson | Co-Conveners: Halldór Björnsson , Severine Moune|
The 2010 flank and summit eruptions at Eyjafjallajökull volcano (Iceland) produced a wealth of data that are providing new avenues in volcanological research across several disciplines, such as in volcano seismology and deformation, geochemistry and petrology of mixed magmas, physical volcanology (i.e. conduit processes, volcano-ice interactions, eruption column dynamics and plume dispersal), volcano-environment interactions and hazard mitigation. The aim of this session is to bring together researchers that are working on different aspects of these eruptions and we welcome presentations on the following topics:
(a) Precursor activity including deformation and seismicity
(b) Nature and depth of magma sources
(c) Mechanisms and time-scales of magma mixing
(d) Modes by which basaltic intrusions can trigger intermediate and silicic explosive eruption.
(e) Origin and evolution of magmatic volatiles in systems of magma mixing, including records of degassing during rise of magma through the conduit.
(f) Eruption mechanisms, including shallow-level conduit processes (i.e. magma degassing/fragmentation) and eruption column dynamics.
(g) Volcano-ice interactions, jökulhlaups and lahars.
(h) Tephra dispersal, including dispersal patterns, transport mechanisms and processes of deposition.
(i) Weather related impact on plume height and ash dispersal.
(j) Remote sensing of the volcanic plumes from the 2010 summit eruption
(k) Environmental and socio-economic impacts
(l) Response and hazard mitigation in relation to the effects of the 2010 summit eruption.
