The 1972 Ruisui earthquake (also known as the 1972 Juisui earthquake) occurred on April 24 at 17:57 local time. The magnitude of this earthquake was given as Ms 7.2 [1] by the United States Geological Survey and ML 6.9 by the Central Weather Bureau of Taiwan. [2] The epicenter was located near Ruisui Township, Hualien County, Taiwan. The intensity was shindo 4 in Taipei and Hualien. [3] Five people were reported dead. The Ruisui Bridge (Chinese:瑞穗大橋) was destroyed. [4] The water treatment plant in Ruisui was damaged.
This earthquake was caused by the Juisui Fault with a vertical movement of 70 centimeters (28 in). [5] [6] The Juisui Fault is a segment of the 150 kilometers (93 mi) long Longitudinal Valley Fault, which is a left-lateral fault with a reverse component. [7] The boundary between the Eurasian plate and the Philippine Plate lies along the Longitudinal Valley Fault. [8]
The 1556 Shaanxi earthquake, known in Chinese colloquially by its regnal year as the Jiajing Great Earthquake "嘉靖大地震" or officially by its epicenter as the Hua County Earthquake "华县地震", occurred in the early morning of 2 February 1556 in Huaxian, Shaanxi during the Ming dynasty.
The Huadong Valley or Hualien–Taitung Valley, also known as East Rift Valley, the Longitudinal Valley or as the Nakasendō Plain during the era of Japanese rule, is a long and narrow valley located between the Central Mountain Range and the Coastal Mountain Range of eastern Taiwan, stretching about 180 km (110 mi) from Hualien City at the north to Taitung City at the south..
The 1920 Haiyuan earthquake occurred on December 16 in Haiyuan County, Ningxia Province, Republic of China at 19:05:53. It was also called the 1920 Gansu earthquake because Ningxia was a part of Gansu Province when the earthquake occurred. It caused destruction in the Lijunbu-Haiyuan-Ganyanchi area and was assigned the maximum intensity on the Mercalli intensity scale. About 258,707-273,407 died, making it one of the deadliest earthquakes in China and disasters in China by death toll.
The 1964 Baihe earthquake, also known as the Great Baihe earthquake, measured 6.3 local magnitude, and occurred at 20:04 CST (UTC+8) on 18 January in Baihe Township of Tainan County, Taiwan. The hypocenter of the earthquake was 20 kilometers deep. The earthquake killed 106 people, destroyed 10,924 buildings, and caused a great fire in Chiayi City. It was the sixth deadliest earthquake in 20th century Taiwan, and the third deadliest post-World War II, after the 1999 Jiji earthquake and the 2016 Taiwan earthquake.
The 1951 East Rift Valley earthquakes were a series of earthquakes which struck eastern Taiwan from 22 October 1951 to 5 December 1951, four of which registered at 7 or greater on the moment magnitude scale, the largest of those being magnitude 7.3 and 7.8 quakes on November 24. Altogether the quakes killed 85 people.
The 1946 Hsinhua earthquake, also referred to as the 1946 Tainan earthquake was a magnitude 6.1 earthquake which hit Tainan County, Taiwan, on 5 December 1946, at 06:47. The quake claimed 74 lives and was the eighth deadliest earthquake in twentieth century Taiwan.
The 2010 Yushu earthquake struck on April 14 and registered a magnitude of 6.9 Mw or 7.1 Ms. It originated in Yushu, Qinghai, China, at 7:49 am local time.

The 1932 Changma earthquake occurred at 10:04:27 local time on 25 December. With an estimated magnitude of 7.6 on the surface-wave magnitude scale, and a maximum felt intensity of X (Extreme) on the Mercalli intensity scale, the quake destroyed 1,167 houses and caused 275 to 70,000 deaths and 320 injuries.
The island of Taiwan was formed approximately 4 to 5 million years ago at a convergent boundary between the Philippine Sea Plate and the Eurasian Plate. In a boundary running the length of the island and continuing southwards, the Eurasian Plate is sliding under the Philippine Sea Plate. In the northeast of the island, the Philippine Sea Plate slides under the Eurasian Plate. Most of the island comprises a huge fault block tilted to the west.
