The strong earthquake in Basel of 1356 was an exception although its impact was not as severe as that of the famous one in Lisbon of 1755. It is strange that in Freiburg there is no testimony about the Basel earthquake. Shock waves certainly must have been felt. On the contrary, the generous help Freiburgers gave to the people of Basel afterward is well documented.

The combined lecture by Drs. Brüstle and Braumann: Earthquakes in Baden-Württemberg from the Middle Ages to today. Historical research and seismological evaluations was hailed as a fruitful collaboration between science and humanities. No wonder that the auditorium was overcrowded. Against my habit, I was late but luckily got the last seat in the first row.
While Braumann had dug up old written testimonies of seismic activities in the region Brüstle had analyzed the events preparing and completing the input for a database with about 10,000 events over the last 1000 years. Braumann found 700 original documents about seismic events unknown so far.
