A series of major earthquakes struck Central Italy between the Marche and Umbria regions in October 2016. The third quake on October 30 was the largest in Italy in 36 years, since the 1980 Irpinia earthquake.
A magnitude 5.5 earthquake struck 8 km (5 mi) east southeast of Sellano on 26 October at 19:11 local time (17:11 UTC) at a depth of 10 km (6 mi). The earthquake was also felt in the city of Rome. In the region of Marche some houses collapsed, Italian media reported. There were also power failures and the telephone lines were interrupted.
A magnitude 6.1 intraplate earthquake struck 3 km (2 mi) west of Visso on 26 October at 21:18 local time (19:18 UTC). The earthquake, which occurred two months after a magnitude 6.2 earthquake in August, struck about 30 km (20 mi) to the northwest of the August earthquake's epicenter. The civil protection, however, estimated the consequences less dramatically than feared. According to official data, a man died because he had suffered a heart attack as a result of the quake.
A third large, shallow earthquake of USGS preliminary magnitude 6.6 struck 6 km (4 mi) north of Norcia at 07:40 local time (06:40 UTC) on 30 October. Early news and social media reports showed heavy damage to some structures. The village of Arquata del Tronto was destroyed as well as the Basilica of Saint Benedict in Norcia. Two women died of sudden heart attacks during the quake.
