Krafla multiparametric experiment
The IMPROVE multi-parametric experiment at Krafla took place from June 17 to July 3 (with some groups continuing further). A total of 41 personnel took place, including 14 Early Stage Researchers recruited under IMPROVE. The experiment has a strong scientific content, as it is described in the project:
OBJECTIVE #1. IMPROVE will attack the present-day major limitation in underground imaging of volcanoes, by concentrating the research of 9 ESRs and their scientific tutorship teams in a coordinated, multi-disciplinary effort aimed at testing current-day models, and developing new ones, at Krafla, the unique place where ground- truth testing can be conducted thanks to direct knowledge of the magma-rock interface.
It also has a similarly strong educational content, justifying the participation of all of the IMPROVE ESRs (one still to be recruited at the time), including those focusing their research activities on Mount Etna.
