1428 Catalonia earthquake
The Catalan earthquake of 2 February 1428, known in Catalan as the "" because it took place during Candlemas, struck the region of Catalonia, especially Roussillon, with an epicentre near Camprodon. The earthquake was one of a series of related seismic events that shook Catalonia in a single year. Beginning on 23 February 1427, tremors were felt in March, April, 15 May at Olot, June, and December. They caused relatively minor visible damage to property, notably to the monastery of Amer; but they probably caused severe weakening of building infrastructure. This would account for the massive and widespread destruction that accompanied the subsequent 1428 quake.
