1356 Basel earthquake

The 1356 Basel earthquake is the most significant seismological event to have occurred in Central Europe in recorded history and had a moment magnitude in the range of 6.0–7.1. This earthquake, which occurred on October 18, 1356, is also known as the Séisme de la Saint-Luc, as 18 October is the feast day of Saint Luke the Evangelist.

After a foreshock between 19:00 and 20:00 local time, the main earthquake struck in the evening at around 22:00, and numerous aftershocks followed through that night. Basel experienced a second, very violent shock in the middle of the night. The town within the ramparts was destroyed by a fire when torches and candles falling to the floor set the wooden houses ablaze. The number of deaths within the town of Basel alone is estimated at 300. All major churches and castles within a 30 km radius of Basel were destroyed.
