This was the biggest earthquake ever experienced by Çeşme in its history. The aftershocks of this quake, like the previous event 2 years before, lasted for a long period, continuing for around 5 more months.
The 1766 Istanbul earthquake was a strong earthquake with epicenter in the eastern part of the Sea of Marmara, in the Çınarcık Basin which occurred in the early hours of Thursday morning, 22 May 1766. The earthquake had an estimated magnitude of 7.1 on the surface wave magnitude scale, and caused effects in a vast area extending from Izmit to Rodosto. In this area, the earthquake was followed by a tsunami which caused significant damage. The earthquake of 1766 was the last major earthquake to rock Constantinople because of a rupture of the North Anatolian Fault in the Marmara region.
An earthquake with a moment magnitude of 7.0 occurred on 30 October 2020 about 14 km (8.7 mi) northeast of the Greek island of Samos. Although Samos was closest to the epicentre, it was the Turkish city İzmir, 70 km (43 mi) northeast that was heavily affected—more than 700 residential and commercial structures were seriously damaged or destroyed. 117 people died in İzmir Province while an additional 1,034 were injured. In Greece, there were two fatalities and 19 injured. The earthquake is the deadliest in the year 2020, and the third major earthquake to strike Turkey that year. The event is called the Samos earthquake by the International Seismological Centre.
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. This extremely catastrophic earthquake had an estimated magnitude of 7.7 to 8.3 at a depth of approximately 61 to 100 km. The earthquake was felt over a very wide area extending from Sicily, Italy to the Levant and North Africa. On the Greek island of Crete, the effects of the earthquake were cataclysmic, over 500 bodies were recovered in the city of Heraklion. Shockwaves from the earthquake were felt intensely, covering all of the Ottoman Empire; present-day Turkey, Cyprus and the Middle East where damage and human losses were reported. In Malta, the earthquake collapsed the Għajn Ħadid Tower—a coastal watchtower built around the year 1638. In Cairo, Egypt, the earthquake destroyed buildings, created seiches in canals, and killed several people. Off the Egyptian and Italian coasts, sailors reported feeling a seaquake.
The Nemuro-Oki earthquake in scientific literature, occurred on June 17 at 12:55 local time. It struck with an epicenter just off the Nemuro Peninsula in northern Hokkaidō, Japan. It measured 7.8–7.9 on the moment magnitude scale (Mw ), 8.1 on the tsunami magnitude scale (Mt ) and 7.4 on the Japan Meteorological Agency magnitude scale (MJMA ).
The 1986 Kalamata earthquake struck the southern Peloponnese Region of Greece on September 13 at 20:24 local time. The 12.5 km (7.8 mi) deep moment magnitude (Mw ) 5.9 earthquake had an epicenter near the coastal city of Kalamata and was assigned X (Extreme) on the Mercalli intensity scale. The earthquake was the result of normal faulting along a northwest-dipping fault and produced surface ruptures. Extensive damage was reported in Kalamata and Elaiochori. At least 20 people died and 330 were injured. Survivors sought refuge at campsites and reconstruction work lasted five years.

A tsunami warning was issued by the National Oceanic and Atmospheric Administration (NOAA) but later cancelled. The mainshock was followed by a number of aftershocks, including three that were of magnitude 5.9, 6.1 and 6.9 respectively.

The 1843 Nias earthquake off the northern coast of Sumatra, Indonesia caused severe damage when it triggered a tsunami along the coastline. The earthquake with a moment magnitude (Mw ) of 7.8 lasted nine minutes, collapsing many homes in Sumatra and Nias. It was assigned a maximum modified Mercalli intensity of XI (Extreme).
The 1968 Aegean Sea earthquake was a 7.0 earthquake that occurred in the early morning hours of February 20th, 1968 local time about 57.1 km (35.5 mi) away from Myrina, Greece. This earthquake occurred between mainland Greece and Turkey, meaning both countries were impacted. 20 people died, and 39 people were injured to various degrees.

The southern margin of the Gulf of Corinth was struck by a major earthquake on 26 December 1861 at 08:28 a.m. local time. It had an estimated magnitude in the range 6.6–6.7 and a maximum felt intensity of IX (destructive) on the European macroseismic scale (EMS). It caused widespread damage on both sides of the Gulf and led to up to 20 deaths and a further 126 people being injured, 18 of them seriously. A series of tsunami waves were reported, with a maximum run-up of 2.1 m.
The 1940 Shakotan earthquake occurred on August 2 at 00:08:22 JST with a moment magnitude (Mw ) of 7.5 and maximum JMA seismic intensity of Shindo 4. The shock had an epicenter off the coast of Hokkaido, Japan. Damage from the shock was comparatively light, but the accomanying tsunami was destructive. The tsunami caused 10 deaths and 24 injuries on Hokkaido, and destroyed homes and boats across the Sea of Japan. The highest tsunami waves were recorded at the coast of Russia while along the coast of Hokkaido, waves were about 2 m.
The 1933 Kos earthquake struck the Aegean Sea region on 23 April. It measured Mw 6.4 and had an epicenter offshore, near Kos, Greece. The earthquake collapsed many buildings on Kos, Nisyros and other islands. At least 181 people were killed with a possible death toll reaching several hundreds.
