The 1951 East Rift Valley earthquakes (1951年縱谷地震系列 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.
Technical data
The East Rift Valley (花東縱谷 Huā-Dōng Zònggǔ) is an area of rugged terrain formed by the interaction of the Philippine Sea and Eurasian tectonic plates in eastern Taiwan.http://www.erv-nsa.gov.tw/user/Article.aspx?Lang=2&SNo=02000026 East Rift Valley National Scenic Area Administration Geology and Topography 2009-08-08 https://web.archive.org/web/20110523084217/http://www.erv-nsa.gov.tw/user/Article.aspx?Lang=2&SNo=02000026 2011-05-23 dead 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.http://scman.cwb.gov.tw/eqv5/research/21vol/MOTC-CWB-87-E-11.pdf 台灣地區十大災害地震圖集 (A Collection of Images of Ten Great Earthquake Disasters in the Taiwan Region) Chinese Preface Central Weather Bureau 中央氣象局 https://web.archive.org/web/20110826205454/http://scman.cwb.gov.tw/eqv5/research/21vol/MOTC-CWB-87-E-11.pdf 2011-08-26 dead 2009-08-08
