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 1999 Chamoli earthquake occurred on 29 March in the Chamoli district in the Indian state of Uttar Pradesh. Approximately 103 people died in the earthquake.
This list of 20th-century earthquakes is a list of earthquakes of magnitude 6 and above that occurred in the 20th century. Sone smaller events which nevertheless had a significant impact are also included. After 1900 most earthquakes have some degree of instrumental records and this means that the locations and magnitudes are more reliable than for earlier events.
The Sagaing Fault is a major fault in Myanmar, a mainly continental right-lateral transform fault between the Indian Plate and Sunda Plate. It links the divergent boundary in the Andaman Sea with the zone of active continental collision along the Himalayan front. It passes through the populated cities of Mandalay, Yamethin, Pyinmana, the capital Naypyidaw, Toungoo and Pegu before dropping off into the Gulf of Martaban, running for a total length of over 1200 kilometers.

The 1968 Tokachi earthquake occurred on May 16 at 0:49 UTC in the area offshore of Aomori and Hokkaido. The magnitude of this earthquake was put at 8.3. The intensity of the earthquake reached shindo 5 in Aomori, Aomori and Hakodate, Hokkaido.
The 1931 Myitkyina earthquake, or also known as the 1931 Kamaing earthquake, occurred on January 28 at 02:35 local time. It was located in northern Burma, then part of British India. The magnitude of this earthquake was put at 7.6. According to some sources the depth was 35 km, and according to a study of Phyo M. M. the depth was 5 to 30 km.
The 1966 Toro earthquake, or the 1966 Ruwenzori earthquake, occurred on March 20 at 01:42 UTC. The earthquake was located near the border between Uganda and the Democratic Republic of the Congo (DRC), to the south of Lake Albert. Some sources put the epicenter in Uganda while some put it in the Democratic Republic of the Congo. The earthquake had a magnitude of 6.8 and a maximum perceived intensity of VIII (Severe) on the Mercalli intensity scale.
The 1948 Litang earthquake (1948年理塘地震) occurred on May 28, 1948, at 07:11 UTC. It was located near Litang, China. Now situated in the Sichuan Province, Litang County was then called Lihua (理化) County and belonged to the defunct Xikang Province. The earthquake had a magnitude of 7.2, or 7.3.
The 1975 North Atlantic earthquake occurred on May 26 at 09:11 UTC. The epicenter was located in the North Atlantic, in an area between the Azores, Iberian Peninsula, and Morocco. It had a magnitude of Mw 7.9, or Ms 8.1.
The 1930 Pyu earthquake occurred on . The epicenter was located north to Bago, Burma, then part of British India. The magnitude of the earthquake was estimated at 7.3, or 7.3.
The 1976 Sabah earthquake occurred at 10:56 am on 26 July near Lahad Datu in the eastern portion of Sabah, Malaysia. The moment magnitude 6.3 earthquake is one of the strongest in Malaysia to be recorded by seismic instruments. It had a focal mechanism corresponding to strike-slip faulting. While slightly larger than the 2015 Sabah earthquake, the 1976 event caused less extensive damage, in the form of cracks on several buildings and ground cracks.
The Afyon Province of western Turkey was struck by an earthquake measuring 6.5 on 3 February 2002 at 10:11 local time. It had a maximum felt intensity of VIII (Severe) on the Modified Mercalli intensity scale. It damaged hundreds of buildings and caused the deaths of 44 people and a further 318 injuries.
The 1912 Maymyo earthquake or Burma earthquake struck Burma on the morning of May 23, with an epicentre near Taunggyi and Pyin Oo Lwin in Shan State. The earthquake was initially calculated at 8.0 on the surface wave magnitude scale (Ms ) by Beno Gutenberg and Charles Francis Richter, and described by them as being one of the most remarkable seismic events in the early 1900s. Recent re-evaluation of the earthquake, however, have revised the magnitude to 7.6–7.9. It was preceded by two foreshocks on May 18 and 21 with respective intensities V and VII on the Rossi–Forel scale, while the mainshock was assigned IX. Shaking was felt throughout most of Burma, parts of Siam and Yunnan; an area covering approximately 375,000 square miles. It was one of the largest earthquakes in the country.
The 1930 Bago (Pegu) earthquake, also known as the Swa earthquake struck Myanmar on 5 May. The moment magnitude (Mw ) 7.4 earthquake had a focal depth of 35 km (22 mi) and maximum Rossi–Forel intensity of IX. The earthquake was the result of rupture along a 131 km (81 mi) segment of the Sagaing Fault—a major strike-slip fault that runs through the country. Extensive damage was reported in the southern part of the country, particularly in Bago and Yangon, where buildings collapsed and fires erupted. At least 550, and possibly up to 7,000 people were killed. A moderate tsunami was generated along the Burmese coast which caused minor damage to ships and a port. It was felt for over 570,000 km2 (220,000 sq mi) and as far as Shan State and Thailand. The mainshock was followed by many aftershocks; several were damaging; additional earthquakes occurred in July and December, killing dozens. The December earthquake was similarly sized which also occurred along the Sagaing Fault.
The 1839 Ava earthquake, also known as the Amarapura earthquake or Inwa earthquake, was a disastrous seismic event that struck present-day central Myanmar on March 23. This earthquake with an estimated moment magnitude as high as 8.3, was one of the largest in the country, since 1762. It was assigned a maximum of XI (Extreme) on the Modified Mercalli intensity scale, and was felt in Rangoon and Bhamo. Damage was enormous in Ava, resulting in the death of hundreds.
The 1988 Lancang–Gengma earthquakes, also known as the 11.6 earthquakes by the Chinese media were a pair of devastating seismic events that struck Lancang and Gengma counties, Yunnan, near the border with Shan State, Burma. The earthquake measured moment magnitude (Mw ) 7.0 and was followed 13 minutes later by a 6.9 Mw shock. These earthquakes were assigned a maximum China seismic intensity of IX and X, respectively. Between 748 and 939 people were killed; more than 7,700 were injured. Both earthquakes resulted in US$270 million in damage and economic losses. Moderately large aftershocks continued to rock the region, causing additional casualties and damage.
The 1988 Myanmar–India earthquake, also known as the Indo–Burma earthquake struck the Sagaing Region of Myanmar, about 30 kilometres (19 mi) from the border with India on 6 August at 7:06 am MMT with a moment magnitude (Mw ) of 7.3 or Richter magnitude (ML ) of 7.5. At least five people were killed, more than 30 were injured, and another 30 were missing as a result. Serious damage was reported in India and Bangladesh, while some minor damage occurred in Myanmar. The earthquake was reportedly felt in the Soviet Union.
The 1858 Prome earthquake occurred on August 24 at 15:38 local time in British Burma. The earthquake occurred with a magnitude of 7.6–8.3 on the moment magnitude scale. It had an epicenter in near the city of Pyay (Prome), Bago. The shock was felt with a maximum Modified Mercalli intensity of XI (Extreme) for about one minute. Severe damage was reported in Bago, and off the coast of Rakhine, an island sunk.
