Moored current and temperature measurements in the Faroe Bank Channel overflow region, June 2012-June 2013

This data set includes measurements from moored instruments from the Faroe Bank Channel overflow region in the period between 28 May 2012 and 5 June 2013. The data set was collected under the project entitled "Faroe Bank Channel Overflow: Dynamics and Mixing Research", with an objective to describe the structure and variability of the dense oceanic overflow plume from the Faroe Bank Channel on daily to seasonal timescales. Mooring arrays were deployed in two sections: located 25 km downstream of the main sill, in the channel that geographically confines the overflow plume at both edges (section C), and 60 km further downstream, over the slope (section S). The measurements delivered with this data set include hourly-averaged data gridded on 5-m vertical separation, after accounting for mooring knock downs using a mooring dynamics model. Complete set of mooring drawings and detailed description can be found in the cruise report (Fer et al. 2016, PDF provided). The article by Ullgren et al. (2016) gives further details on processing of the data set and presents the data set.

Field data, numerical simulations and probability analyses to assess lava flow hazards at Mount Etna

Improving lava flow hazard assessment is one of the most important and challenging fields of volcanology, and has an immediate and practical impact on society. Here, we present a methodology for the quantitative assessment of lava flow hazards based on a combination of field data, numerical simulations and probability analyses. With the extensive data available on historic eruptions of Mt. Etna, going back over 2000 years, it has been possible to construct two hazard maps, one for flank and the other for summit eruptions, allowing a quantitative analysis of the most likely future courses of lava flows. The effective use of hazard maps of Etna may help in minimizing the damage from volcanic eruptions through correct land use in densely urbanized area with a population of almost one million people. Although this study was conducted on Mt. Etna, the approach used is designed to be applicable to other volcanic areas.
