An earthquake, measuring 6.2 ± 0.016[3] on the moment magnitude scale, hit Central Italy on 24 August 2016 at 03:36:32 CEST (01:36 UTC). Its epicentre was close to Accumoli, with its hypocentre at a depth of 4 ± 1 km,[2] approximately 75 km (47 mi) southeast of Perugia and 45 km (28 mi) north of L'Aquila, in an area near the borders of the Umbria, Lazio, Abruzzo and Marche regions. At least 290 people have been killed and dozens more are missing.[4]

Background[edit]
The central Apennines is one of the most seismically active areas in Italy. The Apennines mountain belt were formed in the Miocene to Pliocene as a result of the ongoing subduction of the Adriatic Plate beneath the Eurasian Plate, forming a fold and thrust belt. During the Quaternary, thrust tectonics gave way to extensional tectonics, with the development of a zone of normal faulting running along the crest of the mountain range. The extension is a result of either subduction rollback or the opening of the Tyrrhenian Sea.[1] In the Central Apennines the zone of extension is about 30 km wide, closely matching the zone of observed extensional strain as shown by GPS measurements. Recent large earthquakes in this area have been caused by movement on SW-dipping normal faults.[6]
This was the largest tremor since 2009,[7] when an earthquake near L'Aquila in the Abruzzo region killed over 300 people and displaced about 65,000.
Earthquake[edit]
The quake was initially reported by INGV to have occurred at a depth of approximately 5 km (3.1 mi), with a magnitude of 6.0 Mw and epicentre in the comune of Accumoli.[2] The USGS first reported an earthquake at a depth of 10.0 km (6.2 mi) with a magnitude of 6.4 Mw and epicentre South-East of Norcia,[1][8] but subsequently revised the magnitude to 6.2 Mw The European-Mediterranean Seismological Centre put the magnitude at 6.1.[9][10]
The initial earthquake was followed by at least 40 strong aftershocks.[11] The tremor and a number of aftershocks were felt across the whole of central Italy (from Rimini to Naples), including Rome, Florence, Bologna, and Naples.[12]

As of 27 August 2016, the official figures of the Protezione Civile report that the earthquake caused the death of 290 people: 230 in Amatrice, 11 in Accumoli and 49 in Arquata del Tronto.[32] At least 365 wounded had to be treated in hospitals, mainly in Rieti and Ascoli Piceno, while people with less serious injuries were treated in place.[33]
In addition of the ones rescued with the help of other inhabitants or escaped by themselves, 238 people were pulled alive from the rubble by the timely intervention of the authorities, 215 by the Vigili del Fuoco, 23 by the Soccorso Alpino.[34][35]
Approximately 2,100 people found shelter in the emergency camps.[32] Approximately 4,400 people were involved in the search and rescue operations, including 70 teams with rescue dogs. Logistics made use of 12 helicopters, with 9 more in stand-by.[36]
Damage[edit]
Early reports indicated severe damage in the town of Amatrice, near the epicentre,[37] and in Accumoli and Pescara del Tronto. Sergio Pirozzi, the mayor of Amatrice, stated that "Amatrice is not here anymore, half of the town is destroyed."[38][39] Photos of the destruction depicted a massive pile of rubble in the town's centre with only a few structures still standing on the outskirts.[40]
Cultural heritage[edit]
In addition to the loss of human life, widespread destruction of cultural heritage is also reported.[41][42][43]
In Amatrice, the facade and rose window of the Church of Sant'Agostino were destroyed, and the museum dedicated to the painter Nicola Filotesio, student and companion of Raphael, collapsed.[42] The quake also created cracks in the Baths of Caracalla in Rome.[41] The earthquake was so broad that authorities made structural tests on the Colosseum as well, which was not damaged.[43]
The Assisi Basilica – a UNESCO World Heritage site with frescoes by Giotto and Cimabue that were partly destroyed by an earthquake in 1997 – was declared safe after an extensive survey by the head restorer.[44][45]
