The 1951 East Rift Valley earthquakes were a series of 735 earthquakes which struck eastern Taiwan from October 22, 1951 to December 5, 1951, four of which registered over 7 on the Richter Scale, the largest of those being two magnitude 7.3 quakes on October 22 and November 25. Altogether the quakes killed 85 people.

Technical data
The East Rift Valley is an area of rugged terrain formed by the interaction of the Philippine Sea and Eurasian tectonic plates in eastern Taiwan. Most of the area is sparsely populated by Taiwanese aborigines, but there are larger populations in the cities of Hualian and Taidong. The deadliest earthquake in the series struck at 05:34 on October 22 1951, with an epicentre at 23.9°N 121.7°E, a few kilometres southwest of Hualian City, with a magnitude of 7.3, and was felt throughout Taiwan as well as on Penghu and Jinmen. 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, Hualian.

Names
The earthquake series is sometimes known by different names, including the 1951 Hualian earthquakes and the 1951 Hualian-Taidong earthquakes  - both of these refer to the same series of quakes in eastern Taiwan from October to December 1951.

Damage
The total figures for casualties and damage from Taiwan's Central Weather Bureau are as follows:
 * 85 deaths
 * 200 seriously injured
 * 1,000 lightly injured
 * Around 3,000 dwellings completely destroyed
