The 1951 East Rift Valley earthquakes (Chinese: 1951年縱谷地震系列; pinyin: 1951 nián Zònggǔ dìzhèn xìliè) 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 East Rift Valley (Chinese: 花東縱谷; pinyin: Huā-Dōng Zònggǔ) is an area of rugged terrain formed by the interaction of the Philippine Sea and Eurasian tectonic plates in eastern Taiwan.[5] Most of the area is sparsely populated by Taiwanese aborigines, but there are larger populations in the cities of Hualien and Taitung. The deadliest earthquake in the series struck at 05:34 on 22 October 1951, with an epicentre at 23.9°N 121.7°E, a few kilometres southwest of Hualien City, with a magnitude of 7.3, and was felt throughout Taiwan as well as on Penghu and Kinmen (Quemoy). The second quake to cause significant casualties hit at 02:50 on November 25 of the same year, again with a magnitude of 7.3, this time centred under the town of Yuli, Hualien.[6]

Namesedit
The earthquake series is sometimes known by different names, including the 1951 Hualien earthquakes (Chinese: 1951年花蓮大地震系列; pinyin: 1951 nián Huālián dà dìzhèn xìliè) and the 1951 Hualien-Taitung earthquakes (Chinese: 1951年花蓮–台東地震系列; pinyin: 1951 nián Huālián-Táidōng dìzhèn xìliè) – both of these refer to the same series of quakes in eastern Taiwan from October to December 1951.
