Assessing the most active volcanoes in Iceland to reduce their risk to local populations and infrastructure
Active ice-covered volcanoes present considerable danger to society due to their explosive, ash-rich nature and the potential to generate destructive glacial outburst floods. The ability to monitor their activity is complicated because volcanic and glacial earthquakes can appear identical in the seismic record. However, newly developed waveform correlation approaches could help distinguish between glacial and volcanic seismicity. The EU-funded SIGMA project will apply these methods to an exceptional seismic dataset in Iceland and develop a new automatic classification software. This includes creating a new micro-seismic catalogue to characterise events as glacial or volcanic using statistical analysis tools. Furthermore, glacial events will be used to calculate subglacial hydraulic properties, important for modelling future glacier behaviour.
