This Work Package seeks to further develop, test and implement schemes for pre-eruptive unrest detection. These objectives are distinct from and complementary to those of WP8, which deal with syn-eruptive early warning. Basis of pre-eruptive detection is continuous real-time monitoring, real-time multiparameter evaluation and ‘smart’ algorithms for ‘change’ detection. Goals will be achieved by developing multi-parameter (seismic tremor, deformation, infrasound, velocity change, gas) pre-eruptive unrest detection schemes, to test these schemes using existing databanks from sites with previous eruptions (e.g. Eyjafjallajökull/Bárðarbunga/Mt Etna/Piton de la Fournaise and by undertaking a demonstrator implementation of the detection schemes in Iceland and Italy.
