Calabria/ Southern Apennines
The Calabrian Arc is the last remaining piece of oceanic subduction in the Western Mediterranean. Collisions on either side have formed the Apennines in Italy and the Maghrebides in Sicily. The Calabrian Arc exhibits a narrow subducting slab that extends to >400 km depth and is the most active seismic belt in Italy with high earthquake hazard (e.g., Messina 1908, 100K+ dead). However, the ongoing tectonics of the Calabrian Arc are uncertain. It has slowed and the collisions may be halting the systems, or the arc may be detaching from the collison zones that bound it. We deployed 39 broadband seismometers and 12 ocean bottom seismometers across the Calabrian Arc, the southern Apennines and the transition between them. This experiment will determine the structure of the entire subduction/collision system from the incoming plate to the arc, slab and backarc spreading system.
