The 1946 Xinhua earthquake (Chinese: 1946年新化大地震; pinyin: 1946 nián Xīnhuà dà dìzhèn), also referred to as the 1946 Tainan earthquake (Chinese: 1946年台南大地震; pinyin: 1946 nián Táinán dà dìzhèn) was a magnitude 6.1 earthquake which hit Tainan County, Taiwan, on December 5, 1946 at 06:47. The quake claimed 74 lives and was the eighth deadliest earthquake in twentieth century Taiwan.

Technical details[edit]

The 6.1 ML earthquake struck at 06:47 CST on Thursday December 5 1946, as people in the area were waking up and preparing breakfast. The epicentre was in Xinhua in the centre of Tainan County at a relatively shallow depth of 5 kilometres (3 mi); the rupture responsible was the Xinhua fault (Chinese: 新化斷層; pinyin: Xīnhuà duàncéng). Government geologists in Taiwan believe this fault may have been active a number of times during the (current) Holocene era.[1] There was one major aftershock, on December 17, which measured 5.7 on the Richter scale but caused no additional casualties.[2]

Damage[edit]

According to Taiwan's Central Weather Bureau, the casualties and damage were as follows:[2]

  • 74 dead
  • 200 seriously injured
  • 274 lightly injured
  • 1,971 dwellings completely destroyed
  • 2,084 dwellings partially destroyed

Soil liquefaction and sand boils were observed in central Tainan County, and there was widespread damage to railways, roads, farmland, water pipes and bridges.[2] As the disaster came just a year into the new Kuomintang rule in Taiwan, it served as a test for the new government. It was the most serious earthquake in Tainan County in 84 years.[3][4]
