Azerbaijan lies at the northern boundary of the broad zone of collision between the Arabian plate and the Eurasian plate. The Greater Caucasus mountain range marks this boundary and has been formed in the last 5 million years. The current deformation front is formed by the Kula fold and thrust belt, which has been active for the last 1.5 million years.Long term convergence rates across this belt have been estimated to be in the range 7–14 mm per year, while GPS data give a current convergence rate of 10 mm per year near the Caspian Sea, decreasing westwards to 4 mm per year near Tbilisi. [3]
The earthquake had an estimated magnitude of 6.9 Ms , although estimates as high as M8.0 have been suggested. [4] Paleoseismological investigations near Agsu, across the trace of the frontal thrust fault have found evidence for two earthquakes that may represent the events in 1668 and 1902. [3]
The area of shaking that reached XI on the Medvedev–Sponheuer–Karnik scale (MSK) has been estimated to be in the range 100–120 km, while the zone that reached X MSK was at least 150 km long. [4] Mishlesh in Dagestan was affected by an earthquake at about the same period as the one that struck Shamakhi and if this was the same event, a rupture of 150 km could be indicated. [3]
Aftershocks continued through 1668, until early 1671. [3]
The date of the earthquake varies between sources. The year of this event ranges from 1667 to 1669 in historical sources. From an analysis of all available historical material, Nikonov in 1982 preferred 14 January 1668. [3] Other cited dates are November 1667 (unspecified day) and 17 December 1667. [1]
The city of Shamakhi is reported to have been completely destroyed. The city walls were said to have collapsed, as were the fortress and the congregational mosque. Baku was also affected with the wall of a palace reported collapsed. [3] Landslides were mentioned in historical sources and some of the roads were so badly damaged that caravans had to find alternative routes. [4]
A death toll of 80,000 people is widely reported in sources [1] [4] but a lower value of 6,000–8,000 deaths has also been mentioned. [3]
The 2000 Baku earthquake occurred on November 25 at 22:09 local time with an epicenter just offshore Baku, Azerbaijan.

The epicenter of the Mw 6.5 earthquake was in the Kopet Dag mountains of North Khorasan, near the Iran–Turkmenistan border, about 579 km (360 mi) northeast of Tehran. The earthquake is characterized by shallow strike-slip faulting in a zone of active faults. Seismic activity is present as the Kopet Dag is actively accommodating tectonics through faulting. The earthquake left 88 dead, 1,948 injured, and affected 173 villages, including four which were destroyed. Damage also occurred in Shirvan and Bojnord counties. The total cost of damage was estimated to be over US$ 30 million.

It was one of the most destructive earthquakes in the region, resulting in the loss of up to 30,000 lives.
The 1979 Saint Elias earthquake affected Alaska at 12:27 AKST on 28 February. The thrust-faulting Mw 7.5 earthquake had an epicenter in the Granite Mountains. Though the maximum recorded Modified Mercalli intensity was VII, damage was minimal and there were no casualties due to the remoteness of the faulting. Damage also extended across the border in parts of Yukon, Canada.
The 1902 Shamakhi earthquake occurred on 13 February with a moment magnitude of 7.4 and maximum Modified Mercalli intensity of IX (Violent). Up to 2,000 people died and thousands more were injured in the Shemakha uezd within the Baku Governorate of the Russian Empire. About 7,439 buildings were damaged or destroyed in the city and surrounding villages. Shamakhi had been devastated by earlier earthquakes in 1806, 1859 and 1872. It is one of the most destructive earthquakes in Azerbaijan.
The 1755 Meknes earthquake affected Morocco on 27 November 1755. The earthquake had a moment magnitude (Mw ) estimated at between 6.5 and 7.0. It devastated the cities of Fes and Meknes—killing at least 15,000 people in both cities. The earthquake struck less than a month after another earthquake that devastated Morocco and Lisbon on 1 November. Previously regarded as an aftershock, this earthquake likely represented rupture of a separate fault due to changes in tectonic stress following their first event.
In 1624 the city of Fez in northern Morocco was devastated by a major earthquake between three and four in the morning of 11 May. It had an estimated magnitude of 6.0 Mw and a maximum felt intensity of VIII–IX on the MSK scale. The earthquake caused severe damage in Fez and the surrounding area.
