[5] Greek seismological reports indicated that the earthquake occurred on 27 February 1629, resulting in extensive losses to property in much of Crete, and also causing a few deaths in Heraklion, where houses fell down, trapping people.
In 1893, De Viazis unearthed a series of official documents of the Venetian Administration of Zakynthos revealing that three captains sailing independently in the strait at the time of the earthquake had reported their observations, which was in the form of tsunami waves travelling in the direction of south and southeast posing threats to their ships.
[6] In 1994, after conducting further research, Tsiknakis stated that he believed the previously established year of the earthquake was wrong, and it was in fact 1630.
[3] In 2010, Papadopoulos and others reported that tsunamis had been recorded when strong earthquakes struck the area between the Peloponnese and Crete, not only on 9 March 1630 but also on 6 February 1866, and 20 September 1867.
