The 1915 Avezzano earthquake occurred on 13 January in central Italy at 07:52:42 local time. The shock had a moment magnitude of 6.7 and a maximum Mercalli intensity of XI (Extreme). The epicenter was located in the town of Avezzano (which was destroyed) in the Province of L'Aquila. Around 30,000 direct fatalities and $60 million in damage resulted from the earthquake.


Central and southern Italy in particular have been struck by deadly earthquakes in the last 300 years, with the deadliest earthquake dating back to at least the 1693 Sicily earthquake. Powerful shocks in 1693, 1783, and 1908 as well as 1915 have killed over 30,000 people each.[4]

Damage and casualties

The earthquake took place at around 8:00 local time affecting thousands of people throughout central and southern Italy; the shaking was even felt in Rome.[5] The town of Avezzano was literally toppled from the shaking and only one high-rise building survived.[5] According to Robinson (1915), ninety-six percent of its population was eliminated almost simultaneously, the worst casualty zone. Several other settlements were demolished in the worst of the earthquake. This damage was attributed to the length of the shock, over 1 minute, and the enormous amount of energy released during the tremor. Compound motion of the fault was also a likely contributor to the earthquake's destruction. The structure of the housing also contributed to the collapse; many homes had been built from simple rocks of varying size and were not reinforced by mortar or even wood.[5]

Damage of the earthquake was distributed throughout central and southern Italy. St John's Lateran reported one fallen statue in addition to cracks in the Column of Marcus Aurelius; Rome experienced other minor damage. In fact, damage from the earthquake was diverse; either the location was destroyed or experienced little to no damage.[5]

Survivors were pulled out slowly from the ruins of earthquake-stricken zones. One man survived in a barn for a period of 25 days living solely off of grains and water. After a short time the searchers ran out of space to dispose of the debris as it was too overwhelming in mass, forcing the workers to give up. As E.V. Robinson later described, the remaining "work of excavation seemed to go on in an unsystematic and half hearted way".[5]

Response and relief efforts

Initial reports did not mention serious damage, and not until later that night did the scale of the devastation become clear. The government in Rome assumed local authorities had delayed reporting the facts, and it was rumored that they even tried to remove one mayor from office. However, when trying to serve him notice it became clear that he, together with most of his town's people, had died in the earthquake. Because of World War I the government decided not to accept foreign assistance, and a national rescue and relief effort was promptly started.[5]

Among those nursing the victims was the Venerable Suzanne Aubert. She wrote back to New Zealand in August There are now very few of the victims of the earthquake left in hospitals, but the wounded soldiers keep on arriving. Theirs is a pitiful sight, but I think that the sight of the crushed people was worse. You see only men in the soldiers, while with the other people, there was such a number of women and children. I feel quite at home with my work, but I am forgetting English in trying to understand the different dialects of the poor sufferers. Each province, almost each district has its own, it makes the service difficult. Fortunately we can go a long way with signs.[6]
