The 2008 Qeshm earthquake occurred on 10 September in the Hormozgān Province of southern Iran, 850 kilometres (528 mi) south of Tehran. Its epicenter was near the port city of Bandar Abbas, where an earthquake two years prior had caused damage. The earthquake measured 5.9 on the moment magnitude scale and 6 on the surface wave scale, killing seven people and injuring up to 45. Causing both catastrophic and minor damage, the earthquake devastated up to 200 villages throughout southern Iran, but left the port city of Bandar Abbas almost unscathed. Citizens reportedly panicked when the earthquake hit, emptying into the parks of the city and other open areas.

The 856 Damghan earthquake or the 856 Qumis earthquake occurred on 22 December 856. The earthquake had an estimated magnitude of 7.9, and a maximum intensity of X (Extreme) on the Mercalli intensity scale. The meizoseismal area extended for about 350 kilometres (220 mi) along the southern edge of the eastern Alborz mountains of present-day Iran including parts of Tabaristan and Gorgan. The earthquake's epicenter is estimated to be close to the city of Damghan, which was then the capital of the Persian province of Qumis. It caused approximately 200,000 deaths and is listed by the USGS as the sixth deadliest earthquake in recorded history. This death toll has been debated.

The 2013 Saravan earthquake occurred with a moment magnitude of 7.7 at 15:14 pm IRDT (UTC+4:30) on 16 April. The shock struck a mountainous area between the cities of Saravan and Khash in Sistan and Baluchestan Province, Iran, close to the border with Pakistan, with a duration of about 25 seconds. The earthquake occurred at an intermediate depth in the Arabian Plate lithosphere, near the boundary between the subducting Arabian Plate and the overriding Eurasian Plate at a depth of about 80 km.

On August 17, 1983, at 20:17 PST (UTC+08:00), an earthquake struck the island of Luzon in the Philippines. The shock had a surface wave magnitude of 6.5 and a maximum Mercalli intensity of VIII (Severe), killing 16 people and injuring 47. Seven towns were damaged, several buildings collapsed, and electricity was cut off in Laoag. Features like sand volcanoes and cracks formed during the quake.

Events from the year 1977 in Iran.

The 1994 Mascara earthquake occurred on August 18 at 02:13 local time with an epicenter in a rural part of Algeria. The earthquake measured 5.8 on the moment magnitude scale (Mw ) and had a depth of 10 km (6.2 mi). It caused the deaths of 171 people, left up to 12,500 homeless, and destroyed thousands of homes in Mascara Province. Many homes were damaged or destroyed due to poor building quality which collapsed on the inhabitants and resulted in a majority of the casualties. The national government launched a rapid response effort in its aftermath.

The 1979 Ghaenat earthquakes were a series of large earthquakes in Qaen County, Khorasan Province, northeast Iran, near the Afghanistan border. The first mainshock, known as the Korizan earthquake with a surface wave magnitude (Ms ) of 6.6 and moment magnitude (Mw ) of 6.8, struck on November 14, while the Ms  7.1 or Mw  7.2 Koli-Boniabad earthquake struck on November 27. The two mainshocks were assigned a maximum Modified Mercalli intensity of VIII (Severe) and X (Extreme), respectively. The earthquakes caused extensive damage throughout northeastern Iran, killing an estimated 297 to 440 people and left at least 279 injured.

<span class="mw-page-title-main">2021 Hormozgan earthquakes</span> Earthquakes in Iran

The 2021 Hormozgan earthquakes was a doublet earthquake event in Iran that occurred on November 14, 2021 with magnitudes of 6.0 and 6.4 on the moment magnitude scale. The two quakes occurred just a minute and a half apart, killing 2 people and injuring a further 100.

The 1997 Bojnurd earthquake occurred on 4 February at 14:07 IRST in Iran. 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.

The 1977 Naghan earthquake struck Chaharmahal and Bakhtiari province in Iran on April 6 at 13:36 UTC. The earthquake measuring 6.0 Mw  occurred at a depth of 15 km (9.3 mi) and had a maximum Modified Mercalli intensity of VIII (Severe). More than 2,100 homes were destroyed and at least 348 people were killed.

The 1957 Farsinaj earthquake struck Hamadan province, Iran on 13 December at 05:15 local time. The moment magnitude 6.5 earthquake struck at a depth of 15 km (9.3 mi). The epicenter of the earthquake was located in the seismically active Zagros Mountains. The mountain range was also the location for several historic earthquakes. The earthquake occurred near two segments of the active strike-slip Main Recent Fault. At least 1,130 people died, including over 700 in the village of Farsinaj. Additional deaths also occurred in Dehasiyab, Sarab, and other villages. The earthquake left an estimated 15,000 homeless; poor weather conditions including a winter storm on 21 December killed another 20 people. Several deadly and damaging aftershocks in that month killed a total of 38 people.

The 1958 Firuzabad earthquake was the second destructive earthquake to strike Hamadan province, Iran, in nine months. The Mw 6.7 earthquake occurred at a depth of 15 km (9.3 mi) on 16 August at 22:43 local time. It caused severe damage to over 170 villages in the province. Due to several strong foreshocks, most of the population fled their homes and the death toll only stood at 132 and another 948 were injured. A destructive aftershock on 21 September killed another 16 people.
