An earthquake occurred on November 27, 2005, at 13:52 IRST on the sparsely populated Qeshm Island off Southern Iran, killing 13 people and devastating 13 villages. It was Iran's second major earthquake of 2005, following the one at Zarand in February. The epicenter was about 1,500 kilometers (930 mi) south of Tehran, close to Iran's southern borders. Initial measurements showed that the earthquake registered about 6.0 on the moment magnitude scale, although that was reduced to 5.8 after further analysis. More than 400 minor aftershocks followed the main quake, 36 of which were greater than magnitude 2.5. The earthquake occurred in a remote area during the middle of the day, limiting the number of fatalities. Iranian relief efforts were effective and largely adequate, leading the country to decline offers of support from other nations and UNICEF.
The 2000 Baku earthquake occurred on November 25 at 22:09 local time with an epicenter just offshore Baku, Azerbaijan. It measured 6.8 on the moment magnitude scale and the maximum felt intensity was VI on the Mercalli intensity scale. It was followed three minutes later by a quake measuring 5.9. It was the strongest for almost 160 years, since 1842 in the Baku suburbs and in addition to the capital affected Sumgayit, Shamakhi and neighboring cities. According to the United States Geological Survey, the epicentre was in the Caspian Sea, 25 km to the south-southeast of Baku. The earthquake was felt as far away as e.g. Tbilisi, 600 km northwest of the epicentre, Makhachkala and the Karabudakh and Isberbas settlements in Dagestan.
The Newport–Inglewood Fault is a right-lateral strike-slip fault in Southern California. The fault extends for 47 mi (76 km) from Culver City southeast through Inglewood and other coastal communities to Newport Beach at which point the fault extends east-southeast into the Pacific Ocean where it is known as the Rose Canyon Fault. The fault can be inferred on the Earth's surface as passing along and through a line of hills extending from Signal Hill to Culver City. The fault has a slip rate of approximately 0.6 mm (0.024 in)/year and is predicted to be capable of a 6.0–7.4 magnitude earthquake on the moment magnitude scale. A 2017 study concluded that, together, the Newport–Inglewood Fault and Rose Canyon Fault could produce an earthquake of 7.3 or 7.4 magnitude.
Two earthquakes hit the Italian regions of Molise and Apulia on 31 October at 10:32:58 (UTC) and 1 November at 15:09:00 (UTC). The shocks had magnitudes of 5.9 and 5.8 respectively. Most of the victims were killed and injured when a school collapsed in the town of San Giuliano di Puglia: 26 of the 51 schoolchildren died, together with one of their teachers. In particular, none of the nine children in the school's 4th Year survived.
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 1976 Çaldıran–Muradiye earthquake occurred at 14:22 local time on 24 November. The epicenter was located near Çaldıran, 20 km northeast of Muradiye, in the Van Province of eastern Turkey. The earthquake had a magnitude of 7.3 with a maximum intensity of X (Extreme) on the Mercalli intensity scale. The area of severe damage, where over 80% of the buildings were destroyed, covered an area of 2,000 square kilometres. There were between 4,000 and 5,000 casualties.
The 1895 Quchan earthquake occurred at about 11:30 local time on 17 January. It had an estimated magnitude of 6.8 on the surface wave magnitude scale and a maximum perceived intensity of VIII (Severe) on the Mercalli intensity scale. It caused severe damage in Quchan County, particularly to the town of Quchan itself and there were an estimated 1,000–11,000 casualties. It was the last in a sequence of major damaging earthquakes that struck the area between 1851 and 1895.
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.
The first and most destructive of the 2020 Iran–Turkey earthquakes occurred on 23 February, near Khoy in north-west Iran, close to the border with Turkey, killing 9 people in Başkale, Van. It hit at 9:23 a.m. local time with a magnitude of 5.8 at a depth of 6 kilometres and the epicenter was Qotur district, according to the Iranian Seismological Center (IRSC). About 10 hours later the same area was hit by another major earthquake of 6.0 Mw .
On January 1, 1996, at 4:05 p.m. Central Indonesia Time, an earthquake with an epicenter in the Makassar Strait struck north of Minahasa on the island of Sulawesi, Indonesia. The earthquake measured 7.9 on the moment magnitude scale and was centered off Tolitoli Regency in Central Sulawesi, or 25 km from the Tonggolobibi village. A tsunami of 2–4 m (6.6–13.1 ft) was triggered by this earthquake as a result. At least 350 buildings were badly damaged, nine people died and 63 people were injured.
The western coast of West Sulawesi was struck by a major earthquake on 23 February 1969 at 00:36 UTC. It had a magnitude of 7.0 and a maximum felt intensity of VIII on the Modified Mercalli intensity scale. It triggered a major tsunami that caused significant damage along the coast of the Makassar Strait. At least 64 people were killed, with possibly a further 600 deaths caused by the tsunami.
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.
The Fars region of Iran was struck by a major earthquake on either 22 April or 5 May 1853. The city of Shiraz and the surrounding area were severely affected, with almost all buildings destroyed. At least 9,000 people were killed, with some estimates reaching 13,000.
The city of Blida in Algeria was struck by a major earthquake on 2 March 1825. It had an estimated magnitude of 7.0 and a maximum felt intensity of X (Extreme) on the Modified Mercalli scale. It caused almost the complete destruction of Blida and led to the deaths of at least 6,000 of the inhabitants.
The 1997 Bojnurd earthquake occurred on 4 February at 14:07 IRST in Iran. The epicenter of the 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 region of Ningxia was struck by a major earthquake on the morning of 14 October 1709. It had an estimated magnitude of 7.5 and a maximum felt intensity of X (extreme) on the Modified Mercalli intensity scale. The city of Zhongwei was badly damaged, including a section of the Great Wall. A total of 2,032 people were killed.
The 1641 Tabriz earthquake occurred on the night of February 5 in present-day East Azerbaijan province, Iran. The earthquake had an estimated surface-wave magnitude of 6.8 and an epicenter between Lake Urmia and the city of Tabriz. It was one of the most destructive earthquakes in the region, resulting in the loss of up to 30,000 lives.
The 1977 Bob–Tangol earthquake struck Kerman province of Iran on December 20, 1977 at 03:04 Iran Standard Time. The earthquake measured 5.9 and struck at a depth of 22.7 km (14.1 mi). A maximum Modified Mercalli intensity of VII was evaluated based on damage. It had a strike-slip focal mechanism, which was unusual as the source structure was a thrust fault. It was part of a sequence of strong earthquakes along the 400 km (250 mi) Kuh Banan Fault. Between 584 and 665 people perished while a further 500–1,000 were injured; thousands were also made homeless. Casualties from the earthquake was considered moderate due to the sparsely populated area it affected. Preceded by foreshocks the month before, many residents became wary of a larger earthquake and took refuge outside their homes, contributing to the moderate death toll. However, there were none immediately before the mainshock so many were still in their homes when it struck. Aftershocks were felt for several months, some causing additional damage.
The 1957 Sangchal earthquake struck northern Iran's Mazandaran province on 2 July 1957. It had a moment magnitude of 6.6 or 7.1 (Mw ), focal depth of 15 km (9.3 mi), and maximum Modified Mercalli intensity of IX (Violent). It devastated many communities in the Alborz Mountains and caused an estimated 1,500 fatalities. Damage was estimated at US$25 million.
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.
