NOTES

1   Finkel & Ambraseys supplemented by D. Eginitis, Le tremblement de terre de Constantinople

      Annales de Géographie, 4, 151-165 (1895).

2  1999 MMI based on Barka's 3 flights & field visits, with calibaration against RMS MMI maps;

     du 10 juillet 1894, Turkish General Directorate MMI map ignored as inflated.

3   Assignments tentative; we're missing a key figure from A & F (1987)

4   Eginitis (1895) gives 13,000 deaths
