June 24, 1870 Earthquake: Crete, Egypt, Greece

The earthquake was strong in Athens where it was noted at 17h54m, in Izmir, it was felt on the Islands of Crete, Cyprus, Thira (Santorini), Malta. Damage was not great [in Alexandria] [...] Three shocks occurred in Cairo approximately at 18h30m [..] Two shocks occurred in Beirut and Nablus at 18h [...] felt in the vicinity of Beirut, in the town of Zebdani and in the Anti-Liban range of at 18h 15m and on the eastern shore of the Red Sea. The earthquake was noted in Albania and in the south of Italy. (reference #2130)

This was a large, probably intermediate-depth, earthquake felt throughout the Eastern Mediterranean. It occurred at 18h 3m and was perceptible over an area extending from central Italy to Damascus and from central Greece to the Red Sea [...] Nowhere did the earthquake cause any serious damage, although it was reported from many places far apart [...] The earthquake caused some damage in the region of Marmaris, which had already been affected severely by previous earthquakes [...] Much of the information about this earthquake in modern writers is grossly inaccurate. Sieberg (1928) considers this event to have been centred on Ismailia. Later, Sieberg (1932a; 1932b) placed this large shock just off the Nile Delta, about 100km from Rosetta. His isoseismal map shows Cairo to have experienced intensity IX and Alexandria and Ismailia intensity VIII. Aden is wrongly included among the places where the shock was felt. This in turn misleads Ben-Menahem (1979, 283) who assigns to the earthquake a magnitude ML of 7.2 and a radius of perceptibility of 1500 km. (reference #9116)
