The 2017 Ischia earthquake occurred in the island of Ischia, Campania, in southern Italy. The main shock occurred at 20:57 CEST (18:57 UTC) on 21 August 2017, and was rated 3.9 or 4.2 on the moment magnitude scale.
Despite the moderate magnitude, several buildings and a church collapsed. One woman died in Casamicciola Terme after being hit by rubble that fell from a church.Terremoto a Ischia, crolli a Casamicciola. Morta una donna, ci sono feriti e dispersi.

Damage and debates The collapse of several buildings and the death of two women created much controversy and debate in Italy, because many geologists stated that with a moderate magnitude quake, modern buildings should not collapse.Terremoto a Ischia, i geologi: «Case abusive o fatiscenti, allucinante morire per scosse di questa entità» I sindaci: «Nessun legame fra crolli e abusivismo»
Moreover, Ischia is a zone with a high number of irregular buildings, and many critics considered the poor construction materials as the main cause for the death of the two women and for the damage.Terremoto Ischia, cemento e inchieste sull’isola dove non esiste l’abusivismo di necessità. È solo speculazione
The sharp increase of the population between 1950s and 1980s and the growing inflow of tourists increased the anthropic pressure on the island. Significant acreage of land previously used for agriculture has been developed for the construction of houses or residential buildings. Most of this development took place without any planning and building permits. Many houses and structures across the island sustained moderate to severe damage when the earthquake hit.Ischia, il terremoto o gli edifici: cosa c’è davvero dietro i crolli?
