Earthquake
editThe 6.1 ML earthquake struck at 06:47 CST on Thursday 5 December 1946, as people in the area were waking up and preparing breakfast. The epicentre was in Hsinhua in the centre of Tainan County at a relatively shallow depth of 5 kilometres (3 mi); the rupture responsible was the Hsinhua 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.[2] There was one major aftershock, on December 17, which measured 5.7 on the Richter scale but caused no additional casualties.[3]
Damage
editAccording to Taiwan's Central Weather Bureau, there were 74 people killed by the quake, with 200 people seriously injured and 274 lightly injured. 1,971 dwellings were completely destroyed, while a further 2,084 dwellings were partially destroyed.[3] Soil liquefaction and sand boils were observed in central Tainan County, and there was widespread damage to railways, roads, farmland, water pipes and bridges.[3] 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.[4][5]
