The earthquake is thought to be responsible for an uplift of nine metres (30 feet) of the island of Crete, which is estimated to correspond to a seismic moment of 1 × 10 22 N⋅m (7.4 × 10 21 lbf⋅ft), or 8.6 on the moment magnitude scale. An earthquake of such a size exceeds all modern ones known to have affected the region. [5]

365-07-21: Crete, Alexandria: 35.0 23.0 Many thousands 8.5+ It is considered the largest known earthquake in the Mediterranean. Raised part of Crete 12 metres, causing severe damage and triggering a tsunami that devastated Alexandria. Severe casualties and more than 100 cities in Crete were destroyed. [106] 226 BC: Rhodes: 36.43 28.21
Historical earthquakes is a list of significant earthquakes known to have occurred prior to the early 20th century. As the events listed here occurred before routine instrumental recordings — later followed by discoveries of Earth's tectonic plates, [1] seismotomography imaging technique, [2] observations using space satellites from outer space, [3] artificial intelligence (AI)-based ...
A pie chart comparing the seismic moment release of the three largest earthquakes for the hundred-year period from 1906 to 2005 with that for all earthquakes of magnitudes <6, 6 to 7, 7 to 8, and >8 for the same period. The 2011 Japan quake would be roughly similar to Sumatra. Earthquakes of magnitude 8.0 and greater from 1900 to 2018.
Possible tsunami. Considered the oldest record of an earthquake in the Portuguese earthquake catalogs. [1] 21 July 365 AD Crete, Greece: Thousands 8.5 Devastation in Cyrene & Alexandria by a tsunami. Uplift of up to 9 metres in Crete. Maximum intensity XI (Extreme). 365 Crete earthquake: 26 November 684 AD Nankai Trough, Japan: Unknown 8.4 684 ...
The 1856 Heraklion earthquake, also known as the Crete earthquake or Rhodes earthquake, occurred on the morning of October 12 at 02:45 am local time. [1] This extremely catastrophic earthquake had an estimated magnitude of 7.7 to 8.3 at a depth of approximately 61 to 100 km. [2] The earthquake was felt over a very wide area extending from Sicily, Italy to the Levant and North Africa. [3]
The Hellenic arc is one of the most active seismic zones in western Eurasia. [2] It has regularly been the source for magnitude 7 earthquakes in the last hundred years of instrumental recording and the location for at least two historical events that were probably of about magnitude 8 or more, the 365 Crete earthquake and the 1303 Crete earthquake.
