1908 Messina earthquake
The 1908 Messina earthquake (also known as the 1908 Messina and Reggio earthquake) occurred on December 28 in Sicily and Calabria, southern Italy with a moment magnitude of 7.1 and a maximum Mercalli Intensity of XI (Extreme). The cities of Messina and Reggio Calabria were almost completely destroyed and between 75,000 and 200,000 lives were lost.
