The 2011 Dalbandin earthquake occurred on 19 January at 01:23 a.m. local time with a moment magnitude of Mw 7.2 and a maximum Mercalli intensity of VII (Very strong). The shock occurred in a sparsely populated area of Balochistan, caused moderate damage, three deaths, and some injuries.
The tectonic environment of this region is dominated by the motions of the Arabian plate, the Indian plate, and the Eurasian plate. This earthquake occurred as a result of normal faulting within the lithosphere of the subducted Arabian plate. [2]
About 200 mud houses, including some government offices were reported damaged in the Dalbandin area of Pakistan. [4] [5] [6] Two women died of heart attacks in Quetta after the earthquake, about 330 km northeast of the epicenter, where the Mercalli intensity was IV (Light). [7] [8]
Tremors after the earthquake reached neighboring countries [4] including Bahrain, UAE, Oman, Iran, Afghanistan, and India. It was felt with a Mercali intensity of IV (Light) in Islamabad, Karachi, Muscat, Delhi, and III (Weak) in Kabul, Dubai, and Abu Dhabi. [2]
The 1938 Banda Sea earthquake occurred on February 2 at 04:04 local time with an estimated magnitude of 8.5-8.6 on the moment magnitude scale. Shaking was intense with an assigned Rossi–Forel intensity of VII and intensity of VI (Strong) on the Modified Mercalli intensity scale. This oblique-slip event generated a destructive tsunami of up to 1.5 metres in the Banda Sea region, but there were no deaths.
The 2002 Hindu Kush earthquakes struck in northern Afghanistan during the month of March. At least 166 people were killed with a very large and intermediate-depth mainshock on March 3.

The earthquake could be felt in Mexico City and in high-rise buildings in Dallas and Houston. In Mexico, the Cihuatlan-Manzanillo was the most severely affected area. At least 49 people died and 100 were injured.
The 2013 Balochistan earthquakes were the deadliest to affect Pakistan since 2005. The mainshock, occurring on 24 September, had a moment magnitude of 7.8 and maximum Mercalli intensity of IX (Violent). It had an epicenter located in Awaran District, 113 km (70 mi) northwest of Bela. The mainshock killed over 820 people, injured hundreds of others, and left 100,000 people homeless. The Awaran District was among the worst affected with 80 percent of its housing stock damaged or destroyed. On 28 September, the region was affected by a Mw 6.8 aftershock, killing an additional 15 people. Rescue and recovery efforts were severely hampered by insurgents who attacked military troops sent to distribute aid. These attacks also prompted the Pakistan government to close its doors to international aid.
The 1969 Sharm El Sheikh earthquake occurred on March 31 off the southern Sinai Peninsula in northeastern Egypt. The epicenter was located near Shadwan island, southwest of the city of Sharm El Sheikh, at the confluence of the Red Sea and the Gulf of Suez. This normal-slip shock measured 6.6 on the moment magnitude scale, had a maximum reported intensity of VII on the Mercalli intensity scale, and was responsible for several deaths and injuries.
The 2014 Murmuri earthquake occurred on August 18 in the Zagros Mountains of Iran with a moment magnitude of 6.2 and a maximum Mercalli intensity of VIII (Severe). The thrust earthquake injured 60–330 people and was followed by a number of high intensity aftershocks.
The 1999 Aïn Témouchent earthquake occurred on December 22 at 18:36:56 local time in northern Algeria. The dip-slip event had a moment magnitude of 5.6 and a maximum Mercalli intensity of VII. At least 22 were killed, 175 were injured, and 15,000–25,000 were made homeless.

The earthquakes caused extensive damage throughout northeastern Iran, killing an estimated 297 to 440 people and left at least 279 injured.
The 1991 Hindu Kush earthquake severely affected Afghanistan, Pakistan and the USSR on 1 February. It was an intermediate-depth earthquake with a hypocenter 143.2 km (89.0 mi) beneath the Hindu Kush mountains in Afghanistan. The shock measured 6.8 on the moment magnitude scale and had a maximum Mercalli intensity of X (Extreme). The reverse-faulting earthquake occurred in a seismically active region associated with faulting within a deforming oceanic plate at depth.
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 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 1957 Alborz earthquake struck northern Iran's Mazandaran province at 04:12 local time on 2 July. It had a moment magnitude (Mw ) of 7.1 and occurred at a focal depth of 15 km (9.3 mi). The thrust-faulting shock was assigned a maximum Modified Mercalli intensity of IX (Violent). It devastated 120 villages in the Alborz Mountains and caused an estimated 1,500 fatalities. The earthquake also triggered landslides including one that dammed the Haraz River. Some damage was also reported in Tehran, Qaem Shahr and Sari. The total damage was estimated at US$25 million.
The 1947 Dustabad earthquake, also known as the Charmeh earthquake, occurred in South Khorasan Province of northeastern Iran on 23 September. The mainshock had a magnitude of Mw 6.9 and maximum Modified Mercalli intensity of VIII (Severe). It was accompanied by a Mw 6.1 aftershock on 26 September. These earthquakes killed an estimated 500 people.
