The 1920 Garfagnana earthquake (also known as the Lunigiana earthquake) occurred on 7 September in Garfagnana and Lunigiana, both agricultural areas in the Italian Tuscany region. The quake hypocenter was located 14 kilometres (8.7 mi) beneath Villa Collemandina. The maximum felt intensity was rated as X (Extreme) on the Mercalli intensity scale, and 6.6 on the Richter magnitude scale. It was one of the most destructive seismic events recorded in the Apenninic region in the twentieth century. Due to good news coverage, availability of official documents on the damage and abundance of recordings from surveillance stations throughout Europe, it was regarded as a first-rate case study to improve knowledge of tectonics and macroseismic analysis.
