Short summary
In this paper we analyse the seismic record during the extrusion of a lava spine at Unzen volcano, Japan, in 1994. We find two strong groups of similar volcanic earthquakes which, combined with previously published field and experimental observations, we interpret as repetitive fracturing along the margin of the lava spine. This work demonstrates the potential of combining these different approaches for achieving a greater understanding of shallow volcanic processes.
