What the record says

NCEI’s account, from the sources it cites.

1926, August 17, 01:43 UTC. 39 N, 14.75 E, 100 km, earthquake magnitude 6.0, intensity VII, tsunami intensity 3. Tyrrhenian Sea, Lipari Islands. An extremely strong shock (I=VII-VII) occurred on the Island of Salina after weak underground shocks. Powerful landslides accompanied by a deafening roar occurred in some places of the Island; luminescence, was very strong at first, was observed immediately after the shock, and then it shifted toward the west. The earthquake was felt as a more or less strong one on the northern shore of Sicily from Messina to Palermo, on the eastern shore up to Syracuse, in the provinces of Reggio di Calabria and Catanzaro in Calabria, up to Pizzo on the shore of the Tyrrhenian Sea. A lowering of the sea level indicated the origin of the tsunami waves that gushed onto the coasts of the Island of Salina between Maga and Pollara. (reference #2130)

1926, August 17, 01:42 UTC. Aeolian Islands. 38o34'N, 14o50'E, earthquake magnitude 7.5, intensity 7.5, tsunami reliability 2, intensity 2. A strong shock, probably of volcanic origin, in the Aeolian Islands with epicenter located in the Salina island. Severe damage at Malfa and Pollara, where most of the houses were heavily damaged. Many landslides in the whole island. At Filicudi and Lipari islands only slight damage reported. In the beaches of Malfa and Capo in Salina island, an anomalous sea movement observed, with sea water firstly receding (Cavasino, r188). Further references: Dalmasso (r208), Caputo (r5), Soloviev (r414, r582), Antonopoulos (r392), Tinti (r9). Revisions: Maramai (r624). (reference #4139)

1926 08 17, Aeolian Islands, Italy: Due to a shock near Salina island landslides occurred. An anomalous sea movement was observed in Salina. (reference #10357)

1926, August 17, 01:42 UTC, 38.565 N 14.836 E, questionable tsunami. (reference #11164)

1926, August 17, 38:5 N 14:45 E. cause of tsunami: Speculated submarine landslide associated with an earthquake. Tsunami intensity 2. This is the only tsunami that reportedly occurred in Salina island and it was originated by an earthquake probably of volcanic origin [...] On the beaches of Malfa and Capo Faro, in Salina island, a light tsunami was observed with an initial withdrawal of the sea (Cavasino, 1935). Newspapers reported detailed information on the earthquake, but gave no mention of anomalous sea behaviour. (reference #3078)
