Short summary
We use a multi-disciplinary dataset to show that the Prà di Lama sinkhole was created through several episodic events of unrest. We suggest that fluid circulation along an active fault zone, accompanied by localized seismic creep, control the growth of the Prà di Lama deep-sited sinkhole. Conversely, a connection between events of unrest and the largest earthquakes in northern Tuscany is not identified. This paper provides new insights into the evolution of sinkholes in active fault zones.
