A first report on the historical seismicity of Tunisia was read at the Joint EGS‐ESC‐CEC Symposium (Bologna, 1988). Subsequently, further research has revealed new information and confirmed previous doubts. Careful discussion of sources definitely throws out the famous 408 Utica earthquake and increasingly the effects of the 306–310 and 365 events seem dubious. On the other hand, several sequences (981, 1735, 1835, 1872, 1881, 1887) are better known, although the location of most epicentres still remains vague. While catalogues underestimate the frequency of events in northern as well as in southern Tunisia (where there is a zelzel legend), they continue to overestimate the intensities of modern earthquakes.
