Tectonic Summary

The October 26, 2016 M 6.1 earthquake north of Norcia, Italy, occurred as the result of shallow normal faulting on a NW-SE oriented fault in the Central Apennines. The Apennines is a mountain range that runs from the Gulf of Taranto in the south to the southern edge of the Po basin in northern Italy. Geologically, the Apennines is largely an accretionary wedge formed as a consequence of subduction. This region is tectonically and geologically complex, involving both subduction of the Adria micro-plate beneath Eurasia and the Apennines from east to west, continental collision between the Eurasia and Nubia (Africa) plates building the Alpine mountain belt further to the north, and the opening of the Tyrrhenian basin to the west (the latter of which is in turn related to Adria subduction and eastward trench migration). The October 26, 2016 normal faulting earthquake is an intraplate event, an expression of the east-west extensional tectonics that now dominate along the Apennine belt.

The October 26, 2016 event is currently the largest aftershock of the August 24, 2016, M 6.2 central Italy (Amatrice) earthquake, which caused approximately 300 fatalities, and severely damaged the town of Amatrice.

Authorities scrambled to find housing Thursday for thousands of people displaced by a pair of strong earthquakes that struck the same region of central Italy hit by a deadly quake in August, hoping to prevent a second night for them on the street or in cars. The one-two punch packed by the quakes some two hours apart Wednesday evening meant many people were out of harm's way before the second, more powerful temblor, which toppled many historic buildings that had survived previous jolts. But no one was trapped in rubble and there were no reports of serious injuries. The only death in the aftermath was attributed to a heart attack in a 73-year-old man… Mayors of towns scattered in the mountain region spanning the Umbria and Marche regions say many more homes were rendered uninhabitable, on top of those damaged in the devastating August quake. In the town of Ussita, Mayor Marco Rinaldi said his town had been "devastated," with up to 80 percent of the houses no longer inhabitable… Most buildings were intact, showing only cracks. The mayor estimated that two-thirds of the town's 1,500 houses had sustained some damage (ref #11617)
