We present an up-to-date review of the existing data on the evolution of the Apennine–Tyrrhenian basin system and of the tectonic models developed to interpret the complex evolution of magmatism and volcanism along the Tyrrhenian margins of peninsular Italy from Miocene to the Present. The Tyrrhenian margin volcanic belt lies within a back-arc basin located on top of the NW-dipping Adriatic–Ionian slab, active along the convergent boundary between the Africa and Eurasia plates. It is characterized by significant crustal thinning, high thermal flow and huge production of mantle fluids. Seismic activity is very low and clusters in geothermal and...

The Colli Albani Volcano
The Colli Albani volcano (also Alban Hills volcano) is the large quiescent volcanic field that dominates the Roman skyline. The Colli Albani is one of the most explosive mafic calderas in the world, associated with intermediate to large volume ignimbrites. At present it shows signs of unrest, including periodic seismic swarms, ground uplift and intense diffuse degassing, which are the main short-term hazards. New studies have discovered deposits related to previously unknown pre-Holocene and Holocene volcanic and phreatic activity. In the fourth Century B.C.E. Roman engineers excavated a tunnel through the Albano maar crater wall to keep the lake from breaching the rim and flooding the surrounding countryside, events that had previously destroyed this region several times.
The Colli Albani Volcano contains 21 scientific contributions on stratigraphy, volcanotectonics, geochronology, petrography and geochemistry, hydrogeology, volcanic hazards, geophysics and archaeology, and a new 1:50 000 scale geological map of the volcano. The proximity to Rome and the interconnection between volcanic and human history also make this volcano of interest for both specialists and non-specialists.
