[12][13][10] At 13:50 on 17 May 1916,[11][1] an earthquake of magnitude 5.82 Mw was recorded at 44°07′08″N 12°44′53″E / 44.119°N 12.748°E / 44.119; 12.748, 14 kilometres (8.7 miles) from the coast of Bellariva, a southern frazione of Rimini, in the Adriatic Sea.[15] Many people slept outdoors; families made homeless were welcomed to sleep in Castel Sismondo or its adjoining piazza.[18] The shock further weakened buildings damaged in the 17 May earthquake,[7][11] including in Rimini, Riccione, Cattolica, Santarcangelo di Romagna,[7][13] Gabicce Mare, Savignano, San Mauro, Gatteo, Pesaro, and Fano.[19] Il Resto del Carlino reported:[12][13] Throughout the day of Tuesday 15th on the beach from Bellaria to Pesaro, there was a succession of earthquake tremors with a significant increase in intensity.Nonetheless, Rimini – subjected to far greater torments – did not cease from its usual occupations, already accustomed by several months to repeated telluric movements of higher or lower intensity: on the beach, the usual life of joyful animation continued.L'Avvenire d'Italia reported:[12][13] Around 11 o'clock at night, the wrath of the underground subsided [...] but the people did not dare to dare to sleep in the houses and villas and camped as best they could, on mattresses thrown where there was a little shelter from the wind and the dew, or took refuge more comfortably in the seaside huts.In the popular press, experts responded that the phenomenon was explained by liquefaction, and suggested that the observed leakages were the result of a ruptured pipe.[15] In September 1921, it was estimated that the restoration work on Rimini's municipal hall, whose redesign was entrusted to architect Gaspare Rastelli, amounted to 630,000 lire.[8] Among the earthquakes' few positives, they caused eighteenth-century plaster in the apse of the Church of Sant'Agostino to collapse, revealing forgotten fourteenth-century frescos.[4] Among the destroyed buildings were the ancient Church of San Lorenzo in Strada and the Ceccarini kindergarten, which were rebuilt, and the Amanti-Martinelli Marine Hospice, which was replaced with the Grand Hotel.[4][23] Engineers noted that the Hotel des Bains had insufficiently thick walls for its height, and that buildings in the Fontanelle area had been shoddily built using rounded pebbles bound with low-quality lime.[6] On the morning of 17 August, inspectors arrived overnight from Rome toured Rimini, ordering the demolition or repair of houses and the dispatch, by special train, of materials from dismantled military barracks that could be resited in the city.[5] The authorities of the Province of Forlì stayed in Rimini over the coming days, establishing special commissions in Riccione, Coriano, Misano, San Clemente, and Mondaino.[3][23] The municipal engineers housed people in bathing huts, and decided to build barracks near damaged homes rather than in a large, central camp.[8] Il Resto del Carlino reported on 19 August that pavilions with a capacity for 70 people each were built, alongside 35 wooden barracks, 6 timber wagons, and over 2,000 tents.[26] On 5 September 1916, the central government established a special civil engineering corps office in Rimini to oversee technical services related to the demolition and reconstruction of buildings in affected municipalities.
