The 1905 Kangra earthquake occurred in the Kangra Valley and the Kangra district of the Himachal Pradesh, in India on 4 April 1905. The earthquake measured 7.8 on the surface-wave magnitude scale and killed more than 20,000 people. Apart from this, most buildings in the towns of Kangra, Mcleodganj and Dharamshala were destroyed. The earthquake also had a widespread impact in Jammu and Kashmir particularly in the densely populated Kashmir valley. A total of 7,000 to 8,000 people were killed in Jammu and Kashmir with 4,000 to 5,000 deaths occurring in the Kashmir valley. Widespread structural damage was reported across Himachal Pradesh, Jammu and Kashmir and Uttrakhand. [7] [8] [9]
The calculated epicenter of the earthquake lies within the zone of thrusts along the front of the Himalayas formed by the continuing collision of the Indian plate into the Eurasian plate. [10] Underthrusting of the Indian subcontinent beneath Tibet along a 2,500 km long convergent boundary known as the Main Himalayan Thrust has resulted in the uplifting of the overriding Eurasian plate thus, creating the long mountain range parallel to the convergent zone. [11]
The magnitude 7.8–7.9 earthquake struck the western Himalaya in the state of Himachal Pradesh at an estimated depth of 6 km along a very shallow dipping thrust fault, likely on the Main Himalayan Thrust detachment. The rupture area is calculated at 280 km × 80 km. [12] The rupture did not reach the surface, therefore, is considered a blind thrust earthquake. [12] A more recent study in 2005 estimated the rupture zone at 110 km × 55 km while still not breaking the surface. [13]
The earthquake reached its peak Rossi–Forel intensity of X in Kangra. About 150 km away from this zone to the southeast, an area of increased intensity reaching VIII was recorded. This unusually high intensity away from the earthquake in the Indo-Gangetic Plain included the cities Dehradun and Saharanpur. It was felt VII in towns like Kasauli, Bilaspur, Chamba, and Lahore. [14]
As many as 100,000 buildings were reported to have been demolished by the earthquake. At least 20,000 people are estimated to have been killed and 53,000 domestic animals were also lost. There was also major damage to the network of hillside aqueducts that fed water to the affected area. The total cost of recovering from the effects of the earthquake was calculated at 2.9 million (1905) rupees. [1]
The Assam earthquake of 1897 occurred on 12 June, in Assam, British India at 11:06 UTC, and had an estimated moment magnitude of 8.2–8.3. It resulted in approximately 1,542 human casualties and caused catastrophic damage to infrastructures. Damage from the earthquake extended into Calcutta, where dozens of buildings were severely damaged, with some buildings partially collapsing. Trembles were felt across India, reaching as far as Ahmedabad and Peshawar. Seiches were also observed in Burma.
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. Three weeks later, at least 1,200 were killed during a moderate but shallow event that had a maximum Mercalli intensity of VII. The M7.4 and M6.1 reverse events were focused in the Hindu Kush mountain range area.
The Dasht-e Bayaz and Ferdows earthquakes occurred in Dashte Bayaz, Kakhk and Ferdows, Iran in late August and early September 1968. The mainshock measured 7.1 on the moment magnitude scale and had a maximum perceived intensity of X (Extreme) on the Mercalli intensity scale. Damage was heavy in the affected areas with thousands of lives lost in the first event and many hundreds more in the second strong event.
The 1991 Uttarkashi earthquake occurred at 02:53:16 Indian Standard Time (UTC+05:30) on 20 October with a moment magnitude of 6.8 and a maximum Mercalli intensity of IX (Violent). This thrust event was instrumentally recorded and occurred along the Main Central Thrust in the Uttarkashi and Gharwal regions of the Indian state of Uttarakhand. High intensity shaking resulted in the deaths of at least 768 people and the destruction of thousands of homes.
The 1975 Kinnaur earthquake occurred in the early afternoon of 19 January. It had a magnitude of 6.8 on the surface-wave magnitude scale and a maximum perceived intensity of IX (Violent) on the Mercalli intensity scale, causing extensive damage in Himachal Pradesh, in northern India. Its epicentre was in Kinnaur district in the southeastern part of Himachal Pradesh and caused 47 casualties. Landslides, rock falls and avalanches caused major damage to the Hindustan-Tibet Road. The earthquake affected many monasteries and buildings in the state and led to an extensive restoration work in the late 1970s and early 1980s in Himachal Pradesh. The Spiti and Parachu valleys in particular suffered the greatest damage being on the north–south Kaurik-Chango fault, causing damage to landmarks such as Key Monastery and Tabo Monastery.
The 1881 Nicobar Islands earthquake occurred at about 07:49 local time on 31 December, with an epicentre beneath Car Nicobar. It occurred as two separate ruptures, the largest of which had an estimated magnitude of 7.9 on the moment magnitude scale and triggered a tsunami that was observed around the Bay of Bengal. It is probably the earliest earthquake for which rupture parameters have been estimated instrumentally.
The 1819 Rann of Kutch earthquake occurred at about 18:45 to 18:50 local time on 16 June 1819. It had an estimated magnitude ranging from 7.7 to 8.2 on the moment magnitude scale and a maximum perceived intensity of XI (Extreme) on the Mercalli intensity scale. It triggered a tsunami and caused at least 1,543 deaths. The earthquake caused an area of subsidence that formed the Sindri Lake and a local zone of uplift to the north about 80 km (50 mi) long, 6 km (3.7 mi) wide and 6 m (20 ft) high that dammed the Koree / Kori / Puran / Nara river. This natural dam was known as the Allah Bund.
The 1941 Andaman Islands earthquake struck the Andaman Islands on June 26 with a magnitude of 7.7 to 8.1. Details of this event are poorly known as much of Southeast Asia was in the turmoil of World War II. The quake caused severe damage in the Andaman Islands. The tsunami it triggered was reported along the Andaman and Nicobar Islands, India and British Ceylon. There may have been damage and deaths in Bangladesh, Myanmar, and Thailand due to the tsunami.
The 2019 Kashmir earthquake struck regions of Pakistan with an epicentre in Azad Kashmir on 24 September at 16:02 local time. It had a magnitude of 5.4 Mww and a maximum felt intensity of VII on the Modified Mercalli intensity scale or VIII on the European macroseismic scale. There was severe damage in Mirpur District, causing the deaths of 40 people and injuring a further 850. The epicentre of the shallow quake was near the city of Mirpur, Pakistan. The tremors were felt in the Kashmir region, Punjab (Pakistan), Punjab (India), Uttarakhand and northern parts of India including New Delhi.
The Main Himalayan Thrust (MHT) is a décollement under the Himalaya Range. This thrust fault follows a NW-SE strike, reminiscent of an arc, and gently dips about 10 degrees towards the north, beneath the region. It is the largest active continental megathrust fault in the world.
The Main Frontal Thrust (MFT), also known as the Himalayan Frontal Thrust (HFT), is a geological fault in the Himalayas that defines the boundary between the Himalayan foothills and Indo-Gangetic Plain. The fault is well expressed on the surface thus could be seen via satellite imagery. It is the youngest and southernmost thrust structure in the Himalaya deformation front. It is a splay branch of the Main Himalayan Thrust (MHT) as the root décollement.
The 1833 Nepal–India earthquake occurred on August 26 at 22:58 local time (NPT). This earthquake had an estimated moment magnitude of 7.6–7.9 and struck with an epicenter somewhere in or near the Kathmandu Valley. The earthquake caused major destruction in numerous towns and villages in Nepal, northern India, and Tibet. The earthquake was also felt in Chittagong, Bangladesh. Despite the extent of the damage, the number of fatalities resulting from the earthquake was surprisingly low, at approximately 500. This was because the mainshock was preceded by two smaller but intense foreshocks earlier that day, causing many residents to take refuge outside their homes.
The 1906 Manasi earthquake (玛纳斯地震), also known as the Manas earthquake occurred in the morning of December 23, 1906, at 02:21 UTC+8:00 local time or December 22, 18:21 UTC. It measured 8.0–8.3 on the moment magnitude scale and 8.3 on the surface-wave magnitude scale. The epicenter of this earthquake is located in Manas County, Xinjiang, China. An estimated 280–300 people died and another 1,000 more were injured by the earthquake.
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 1555 Kashmir earthquake occurred at around midnight in the month of Ashvin in the Hindu calendar, or September in the Gregorian calendar, although the exact day of occurrence is not known. The earthquake seriously impacted the Kashmir Valley in present-day Pakistan and northwestern India. A moment magnitude (Mw ) of 7.6 to 8.0 and Modified Mercalli intensity of XII (Extreme) has been estimated for the earthquake. Thought to be one of the most destructive in the Kashmir Valley, the earthquake caused serious widespread damage and ground effects, killing an estimated 600–60,000 individuals.

Striking 214.5 km beneath the Hindu Kush mountains, the moment magnitude 7.4 quake affected three countries, killing at least 26 people and injuring several hundred.
The 1885 Kashmir earthquake, also known as the Baramulla earthquake occurred on 30 May in Srinagar. It had an estimated moment magnitude of Mw 6.3–6.8 and maximum Medvedev–Sponheuer–Karnik scale intensity of VIII (Damaging). At least 3,081 people died and severe damage resulted.
The 1803 Garhwal earthquake occurred in the early morning of September 1 at 01:30 local time. The estimated 7.8-magnitude-earthquake had an epicenter in the Garhwal Himalaya near Uttarkashi, British India. Major damage occurred in the Himalaya and Indo-Gangetic Plain, with the loss of between 200 and 300 lives. It is among the largest Himalaya earthquakes of the 19th-century, caused by thrust faulting.
Bhutan was struck by a major earthquake on 4 May 1714. It had an estimated magnitude of about 8.1 Mw and caused shaking that reached IX (Violent) on the Modified Mercalli intensity scale. It is thought to have been caused by rupture of the Bhutan part of the Main Frontal Thrust. Damage was reported from west central Bhutan and northeast India. The earthquake resulted in "many fatalities".
