The 1916–17 Nantou earthquakes (Chinese: 1916年南投地震系列; pinyin: 1916 nián Nántóu dìzhèn xìliè) were a series of earthquakes which affected central Taiwan in 1916 and 1917, causing heavy damage in sparsely populated Nantou County and claiming 71 lives. The strongest quake registered at 6.8 ML and besides the loss of life caused widespread damage to agricultural and forestry industries in central Taiwan.
Technical data
editThe series consisted of four main damaging quakes and dozens of smaller quakes which were not so damaging. The first major quake, on August 28, 1916, was the strongest at magnitude 6.8, but the hypocentre was relatively deep in the earth's crust. The most deadly quake in the series came on January 5 of the following year, registering at 6.2 on the Richter scale with a shallow hypocentre, killing 54 people.[1]
Seismometers were installed in the area in 1898 shortly after the Japanese took control of Taiwan, but there was relatively little seismic activity in Nantou between then and 1916.[1]

- 70 or 71 dead
- 98 seriously injured
- 208 lightly injured
- 1,212 dwellings completely destroyed
- 1,821 dwellings partially destroyed

At the time the camphor industry was a major contributor to the Taiwanese economy, and the forested mountains of Nantou were where the majority of camphor trees were felled and processed. The earthquake destroyed 98 camphor extraction facilities, seriously affecting the local economy.[2]
