The presented seismic exploration experiment exhibits the potential of using a low-cost survey design for 3-D imaging of the subsurface. In this case study, a deep layered intrusion and its feeder system are investigated. The new insights into the tectonic evolution and mineralization potential of the studied region in Finland evidences a complex, layered system rather than a simple magma channel. Furthermore, a major fault is identified that may influence how the development of mineral deposits in the area are interpreted. In summary, this work offers new tools and insights for exploring valuable underground resources in hard rock environments. This is a timely scientific result not only for Europe but has influence on people's sustainable living worldwide.

I concur with the AE's assessment that this paper presents valuable new models on the Permo-Triassic evolution of the Alps.

A must-read on gender gaps in seismology authorship.

The paper represents a very detailed study of the geophysical precursors recorded before and during a major recent explosive eruption. Moreover, the results permit to partly validate and discuss recent models of volcano unrest and have large applications for the monitoring of hazardous volcanoes worldwide.
