Willis (1928) with corrections

Willis' (1928) original catalog mistakenly listed Al Hejira dates from an Arabic language source (originally Al-Soyuti) as Julian calendar dates. Thus a number of earthquake dates in Willis' original catalog are off by around 620 years. Willis wrote a correction in 1933. Ambraseys (1962) wrote a later article correcting these errors in detail. Ambraseys (1962) noted that some of Willis' mistaken dates had entered Sieberg's catalog which then propagated into more modern earthquake catalogs and created phantom earthquakes. Ambraseys (1962) list is included here

NOTE. Toponymics, Provinces, Departments etc. have during historical times had many changes. The names used by As-Soyuti are a mixture of Arabic and corrupted Greek. A useful set of volumes in tracing out places in Syria, Palestine and Egypt is Abul-feda's Geography translated from the Arabic by M. Reinaud and S. Guyard (Geographie d'Aboulfeda, 2 Volumes, a l'Imprimerie Nationale, Paris 1848).
